UV Mapping A Milk Jug in Cinema 4D

what's up guys I'm Lee Williamson and today I have an awesome tutorial for you so UV mapping no no no no don't run away when I'm done you'll feel a lot more confident at least that's what I'm hoping so without further ado let's dig in red so I've got this milk jug and before I start you to be method if I tell myself division surface long you can see it's relatively low poly but I want to make sure that I have enough segments on it before I put my UV map on it otherwise the UV map could be quite stretched over this so when I took my subdivision service on I'm going to turn my subdivision rent up to down to 1 and show you what it looks like an editor also and at least it gives just some extra sections over there and then what I can do is I can bake this down and then I can always put this back in another subdivision service to make this even smoother once I've got my UV map on it so let's just call this mug then we're going to go into our UV a bitmap edit mode and now this is your modeling tools and this is your UV editing tool so we go into our UV Poly's that's how you work with your poly islands when UV mapping on the side so first of all it's all selected and all I'm going to do is I'm going to go down my projection just press frontal and right now this is where my camera set is it's at the front so that actually let's just select it all again control press frontal then press e on my keyboard which is your move tool and just move it off the stage and then we're going to slowly but surely go through cutting this up to make your map out of it so first of all if I just go to my standard and I create a new that's just clueless UV you V mr. Scott movie and I'm gonna go and choose my UV good you can just get this anywhere on Google quite easy to pick up and I'm going to drag that UV grid onto my luck jug right now you can't see it so you would go into your editor and you change your texture preview size to no scaling and it should be nice and sharp you can see this is a very terrible UV at the moment now just so you bear in mind this UV is currently all sitting on top of this little tag called a UV tag so when you go into the UV edit mode all that information is being stored for this on that little tag so if you ever not be able to see it appear just click on that tag and I should appear again or if you wanted to start a newbie map you could just delete that it's just going to my user and you can go to chuckling yeah tags UV tags setting you you set from projection and it will give you a new tag so just go back and try UVs and the first thing I want to do is I want to cut this up so I could start off on the outside of the jug so what I'm gonna do is I'm gonna go back to my pulleys and tell you what if I just turn this or for now I can do I just go to Lee user and I create an L just a little trick to make life a lot easier and I'm just gonna drag that UV map on to the null so I could just drag it on and off whenever I'm modeling it so it's not in my way when I'm trying to see my segments so I'm gonna go to the top of the mug and press ul if you leave you my loop selection ul there a loop selection at the top and then down to just where it sneaks underneath a so up there so I've selected the top part of my UV and the bottom part of it and then I'm going to press UF and fill that selection and now I'll fill that full selection now before one reckless I need to have a scene where I can uncut it almost think of it like origami or skinny a pig skin animal skin or whatever it is so I'm gonna go into my edge tool now let's just click offer to edge tool okay they're working perfectly fine and I'm going to work in a seam so we can have the seam either at the front or at the back properly we've go better to have there seem kind of at the back where it's a little bit more hidden so if I press um I can use my new call this um you um is cool to have path selection tool torrid miles will just let you guys know before I go tender and I'm gonna select all the way down and keep going down here until I get down she I don't even have to go that far away I can just go down roughly about there that's fine so I've selected that full the the Polly's and the edges and then I'm going to go into relax UVs and I'm going to select cut cut select edges and now these are the edges that are selected over there so it remembers those so it tells it where to unfold it from so you can choose to choose a less cm or a if a bf either one try out some produce different kinds of results and I press apply and that's gonna unwrap the UVs like so and you can see that I lens over there and I can press e on my keyboard ye here we go I have to press that again press E and bring it down to the end now what I'm gonna do is I'm gonna put that UV mapping back on here again so you can see what's actually happening for I press T on my keyboard and I can scale this UV map map up press R and rotate it you can see what's going on right now is there is where the seam is so almost imagine you cut this up and opal devout like a piece of paper and that's where the seam is and it's seamless on the other side so a kind of that is where the seam is there and the seam is there and then it's perfect there now the one problem you may notice already is that these lines [Music] see if I'm available decide are skewing down and skewing up and screwing down and they just all look really messy now that might work when you're doing UV mapping for character but it doesn't quite work when you've got more hard surface modeling so I found another technique that could work you can go into your projection of the year and if you click on say frontal and up frontal try try cylinder Celinda looks like it wraps up nicely so when I click on cylinder now it's unwrapped it looks a little bit squished so I can go into transform and put the X scale to two and a press supply and that looks like I stretched out the poly is a lot I set a meter and then I can press T on my ski book keyboard and scale it back down and now they are quite nice but you're gonna notice something that's really stranger is it's missed with these poly Islands and remember originally the seam didn't cut at them the milk spout it cut at the back so I'm gonna show you if I clicked on this island it actually shows you where the Islanders of year see you will square there and little square there I like here and yeah so what you could do is you could press you select your islands let's select some of our islands okay let's make our brush a little bit bigger if you press your middle mouse button you can make your brush bigger by pressing the mouse in to the right and we can select some of these islands okay where is it selecting up to you I'm tree there and I'm there let's zoom in there make sure that the island is fully clicked and where does that seem go to you okay so we need if you notice our scene was supposed to go to there so hold down shift and just select the rest of those islands I see man that's cool and then I'm just gonna press E and I'm gonna move it to the other side and almost think of this like a puzzle where those pieces were meant to go inside there if it perfectly so all I need to do is really zoom in nice and close press e on my keyboard and watch what happens on the right-hand side here when I line these up zoom in nice and snug that's it but I used to hate doing this but I'm starting to find it more therapeutic once you get the hang of it and now we have a very nice clean UV so just by the way if you want to select all the islands you just press eww and it does the whole selection and then you just press the key and you can move it to the middle so there we go we've got the seam on the back nice and neat and we can do the same thing for the other side but now with this technique we don't need to use an edge selection tool to cut down the seam because we're going to make the seam ourselves and this new technique I showed you so we can go back to our selection and since it's already selected over here let's just take this UV and just drag off this so I can see my selections and we can go you and it's UI for invert and it inverts your selection so now I've got my mug jug selected on the inside but I don't want the handles licked so I can go impress you and then hold down control and it will unselect that handle so now that we just have the inside whoo and what we can do this is if you can't see anything over here it's because you just have to select back on your UV tag and zoom nice and closely zoom in with the two and pan around with the one by the way and we can do the same thing again we're gonna press cylinder it's gonna unwrap let's try pressing relax work nope frontal and then cylinder mm-hmm it's not so neat when it unwraps what's the reason for that okay what I'm gonna do is let's see if I can actually deselect the circle underneath EF you hell you f okay for whatever reason we'll selecting the Palio Islands underneath there so now it should just be the inside and you know what I want to actually get rid of these this part of the violin because I actually want that to be nice and neat the flat bottom of the the jug so just as the jugs comes to a flat surface from about year I can click on the island press control then you have control now unselected that there knob just selected the inside without the the bottom or the inside and now let's try it back to cylinder perfect now the islands have come out great so once again I'm gonna drag that texture back on you so I can see what it's what it's looking like and see once again it's looking nice day so we're gonna clean that up we're gonna go into transform set a scale on the x value to two and what it's going to do it's going to double the length like that when I press T and I wait sit back on your again surely this better be a fast way to take back and forth but I don't know it so T scale it down he bring it down yeah and let's see I'm just gonna bring this right off the stage IVM just because all this muck at the bottom I'll show you how to clean that up afterwards now which side of the seam do I actually want on this I probably want the seam not to be on there I wanted to be on guess on that side so I'm going to do the same thing as before let's just see how far where's the middle okay probably need to select a few more islands select up to there maybe and that looks at the middle to me cool like a puzzle we're going to do the same thing again press e on a keyboard move it to the other side zoom in with a two key move around pan zoom in again with the two pan with the one key this is even nice and close and slotted in overlay boom and there we go it's nice and neat I'm really happy with that cool so we have these two very neat sizes reason method sizes because ever allows these sizes aren't the same size but you know what don't worry about that for now it's just rektd over there the next thing I want to do is when unwrapping things you don't always get the perfect shapes to to paint on he's always going to be seen so I decided that I would mind that the visit him at the bottom because otherwise there's no way that would unwrap it properly if you have another way but all means show me so if I press ul on the keyboard and then you F hold down shift and select the inside of that tell you what I'm just going to drag that off there again so you can see what I'm doing and then click back on the UV tag and I'm going to go into top view right so top view so you can see the perfect circle and then I'm going to go into projection and I'm going to choose frontal so when you choose frontal chooses where the camera is situated so when I press it it turns it into a perfect circle because the camera is sitting at the top so I can press e he move that around T and scaled it up boom all sorted and then I can do the same thing for the side he'll he you F and fill that selection going to my top view again okay okay I'll talk to you and press fun tool again and then click back on UV Poly's press E and move it down there cool so let's just drag that back onto my monk model so we can see where we are right so I'm happy with that just looking fairly neat and for the next but wouldn't have to open that handle now the handle may be a bit troublesome but I figured it out and it's using a fairly similar technique that I used in the beginning and this circumstance so I I couldn't really go for that flat version so let me show you what I meant so I'm just going to drag it off there again and I'm gonna you f select the whole entire handle then press the edge selection tool I'm gonna go for a seam that's not something hidden which I think it's this corner if i press e and then double click it should select that whole entire side edge and then I press you what was that one I called again um you can't find it just think um um that's one way I remember um so selective to the corner and probably up to about there so imagine when you cutting a piece of paper part you need to find a place where it's going to cut apart and I kind of figured out that you'd have to slice along the side and then slice it down to that corner to then unwrap this handle and the same thing goes for this edge of ear Izu min to that edge it's gonna go right down to that very corner okay I think I think I got it right so cool right so then we're going to go into back on two V's and make sure the cut edge is selected is up is ticked and then press apply and there we go it is unwrapped so essentially that's what it looks like and then you can always go to a bf and press apply maybe it makes more straight version of it much more pleasing for a geometric shape that we have here and we can then press E and move it onto the stage right so we have a sword I'm just going to press save and I'm gonna press ctrl and select all of these and then I can go into my optimal mapping and I'm gonna press equalize island size and realign and press apply and what that does actually if I press apples ed let me just put that you'll be met back on you yes you notice all these islands are different sizes so the numbers on this side compared to the numbers on that side would be a different size so notice one small thing I want to fix if I click on yeah so this inside face you can notice these numbers or backwards numbers should never be backwards because when you're painting your textures everything is gonna come backwards if you have sent our typography that's gonna be running on your models they're gonna look backwards so let's click on your press UW and we're gonna go into UV command and we're gonna choose something called Murray you and boom flips around the UV map there we go that's nice and then on this side well since I can't see that one I'm gonna have to just select all of these let's select all of them on optimum mapping realign and equalize the eyelets what it's going to do is to make all these islands the same at the same size so that all the numbers should all match and as you know it's just on this handle that number is backwards so I'm going to do the same thing again click on their press u W go to UV commands and Marie you and that should flip the other way around and there we go that looks nice and you know if I press E and move it around you can see the numbers seem to be right now I don't if you've ever gone to pond to pinterest you know some people make a real ball out of getting this all nice and leet out of a layout so that you know the more stretch that your UV map polygons are over this whole entire canvas the higher resolution that your image can be so some people try and fit these circles here and year and year I'm not really going to cover that but if you know if you are a keen 80s kid like me and like to play the game Tetris you're welcome to go and cap your islands and move them around and you tell your happy about where it's it's you know it's it's up to you it's all personal cool so the next thing I'm going to show you is how to create a texture so we're going to go to our materials and we can go file new material and we're gonna click this little red button called and that should just a no idea what it does but gets it started and then there's a very transparent little X over here I really wish cinema4d would make that a lot more parent but if you double click it it comes up with the size dimension of the UV map so I've got mine on 4096 by 4096 and then you can choose the color and preferably this will be the color that you would you want your your UV map to start off with and most people like to texture the UV map with a base color that's darker than the darkest shading on your your picture so for example if I'm going to choose metal I'm gonna make sure that that's a slightly bluish metal and it's gonna be nice and and fully dark and then when I here brush on it all my highlights will kind of build up from lighter colors so I'll go OK and then I can call this a mug texture like texture I press ok and then I can drag that mug texture on top of my mug so currently if I had to go back into my normal layout there are two textures on your so you know right now this one is sitting above that in the hierarchy so essentially it's just holding two textures you can always delete this UV grid if you want going back to my UV edit mode press save and I'm gonna go into file at the very top now I don't know why didn't have a file save every year considering this is where your text result but hey that's that's the way it is see there's your materials I'm gonna go to file and we're gonna click on that material file save as and we don't want it if we're gonna visit a PSD because we are gonna be airbrushing different layers on there so PSD okay and then I'm gonna grab my texture the yay whatever that's cool press save boom and you got to texture and then you just save that and what we're gonna do next is we're gonna select all the islands and we're going to go to image or is it layer and outline Poly's now there's a color via this color is white so you can choose a different color if you want just by double clicking it and choosing whatever color you want I'm just gonna keep it white but just to let you know that that's the color it's it's basing what I'm gonna do next off so layer up line police and it's gonna create outlines on your poly Islands and now this is essentially all right to say controls arigon controls that again go down over here whoo Danya and press on new layer and we're gonna call that outlines shouldn't do it on a background layer and we're gonna go back to the layer outline Poly's and now if you can I on and off just like in Photoshop you have your hard lines with your polygons and press save and here we have a texture and hard lands on there and what I usually do is I take the opacity and I'd pull it nice and low I'll do that cool and create a new layer and let's just coulis highlight whatever you're going to call it and then you can start to paint on you say this is say we actually wanted this to be maybe a darker shadow underneath the the inside of the mud so I can they read that and I can paint inside here and paint inside here and create another layer and who knows we want a highlighter via perhaps I will cover a tutorial next on on how to paint a very nice UV but just for this sake I'm just showing you and then we're gonna turn the app lines off and we turned off the outlines because once we do want to see it and cinema4d we don't want to see that lay on it's just a guide layer and then press ctrl s and we save it and then all we need to do is to see it is to double click go into our color this is where the texture is sitting drop down this little texture is a texture and this Larry here and just say this should be a really load image and just say yes and there we go you have started to paint your texture directly on your mug now you are a professional UV mapper so go ahead and make something awesome I hope you guys enjoyed the tutorial if you did please like share and subscribe as I very much it appreciate it and as you know my subscribers are quite low and during this lock down I'm hoping to punch that level up and the only way I can do that is with your guy's help so if you can I'd be very much appreciated if you think this content is worth sharing to do so you know what I appreciate it thanks guys bye
