Clo3D Displacement maps in Photoshop

so in this tutorial we're going to look at how i used a displacement map to create a raised embossed effect of a graphic on the sleeve of my coat for my icde project in khloe in order to create a displacement map you need a graphic that you're going to raise and then a map of that graphic in this case i want the letters iacde going down the sleeve but i want them going down sideways the first thing i'm going to do is go into image image rotation 90 degrees clockwise so now i have it turned and the next thing i want is to get rid of this white area so that it doesn't cause us problems and because this is a background if i try to just delete the white it's going to give me some issues so if i go over into the layer stack right click on background and hit layer from background and hit ok this is now going to let me get rid of the white and have a transparent area around it so if i go over here and select the magic wand tool and click on the white area i can simply delete and this checkerboard pattern means this area is going to be transparent i'm going to have no pixels of color or information around it which is exactly what we want now i want to go and get rid of these two areas so i hold shift and click on them and hit delete so if i just save this it's going to save it as a jpeg and jpeg is going to give it a background again so in order to not have that we save it as a png file so pngs are the ones that where you can have an image with a transparent background on it we use those a lot so i'll go into save as and icd graphics and this and i'll change this from psd which is a photoshop document to a p n g very important and there have my saved graphic file but now i need the displacement map so now that i've saved as a png file you'll notice that it still maintained the document as the original jpeg file so in order to create my map i can just revert to the original but now it's turned around again i'm going to rotate it okay so with maps you need to think about well with displacement maps think about black as being 0 and white as being 100 whereas 0 is the lowest so black is the lowest and white is the highest and with a graphic on a garment we don't want to go from 0 to 100 in a hurry because that would create very sharp edges and can sometimes create really ugly graphics and club so we want to bevel those edges a little bit and the way to do that is to convert some of the edges to gray so if black is zero white is a hundred a mid-tone gray a fifty percent gray would be half as high so if you can think about that continuum in terms of height you can start to imagine how you could play around with more complex levels of grayscale to create even more interesting levels of height and and graphics and we'll get into that a little bit later when we look at some alphas and substance painter because it's the same concept when when using height channels in substance painter but for now let's just concentrate on closed displacement map so because i want my graphic to be raised and currently it's black and the background is white which would make my background raise up and my graphic sync down i want to revert this so the easiest way to do it would be to just go to image adjustments invert and there i have my black background and my white graphic so in order to get those softer edges we want some grayscale in there so the easiest way to do that would be go into filter blur gaussian blur and you can play around with the radius if i turn it way down then i only get a little bit of that gray in there i turn it way up whoa that's crazy um that would just be way way way too soft so i'm gonna put it around in this case let's say five pixels so that gives us a little bit of blurring a little softness it's going to smooth out that edge so i will now save this as a jpeg as iacde displacement so now we go back into claw so to add my graphic i am going to go into the 2d pattern window bar up here and click on this button which is the graphic and i will say select my iacd graphic and click on my pattern piece now if you know the specific dimensions you want like if you're making a label or something it's easy to enter the dimensions in here but for now because we see that the bounding box fits within my pattern piece i'm not going to play with the scale yet so i'll just hit ok and it's important not to play too much with the scale until you've got your displacement map placed because then they're not going to line up correctly so i've placed my graphic in and then over here so you see how like with the buttons we inserted a texture the graphic is treated the same way it's a texture and in order to get stuff to line up i'm going to go and grab my file as a dip displacement map so here i'm going to click and i'm going to select my displacement file now they're put in together and though you don't see it now because we don't see it in the 3d preview window if we went and looked at the render file we would see that it's given some volume but now if i wanted i could play with a scale and to do that you go up to the other button which is the transform graphic button and then i can click on that graphic and then here if i wanted to scale it or i could rotate it but we're not going to do that we'll leave it there and so when we go into the render window it's still flat because i haven't changed the displacement amount so let's go back to 2d and click on my graphic so under the displacement map you've got some things that you can change the amount in millimeters is how much you're going to move the graphic away so let's set this as something like 5 and then leave shift and clipping we're going to reduce the particle distance a little bit because that'll just make us a smoother effect so let's change this to say two and it's just for this area so it's not going to get crazy slow but with that change let's go back and refresh and see what happens we see that the edges are a little bit jagged maybe too sharp so i need to increase the blur a little bit see that it's not a nice effect so let's just go ahead and delete this now photoshop documents are linked so if i wanted i could just refresh um the file from photoshop but it could be easy to get mixed up and get lost so i prefer to just get rid of it and start over it doesn't take that much longer so we go back into displacement and we're going to put more of that blur on so let's turn it up to say seven seven and a half ish and save it back to chloe place my graphic go grab my displacement map let's turn this up to say five turn the particle distance down to two and a half why not let's see and go back and see what it looks like now that's looking better now if i had some separation that i didn't like if it looked like the letters were floating above the surface that's where you can go and play with the shift amount and put in a negative amount and it'll start bringing it back down toward the code and maybe if you've put some crazy amount like 15 or something see so you want to be a little subtle with the effect and that looks maybe a little too much so let's turn it down to three and a half that looks better and to make this really stand out from the background because right now we've just we've raised this graphic and it's set to fabric matte so let's change it to plastic i see now we get a bit of a shine but that's maybe too much so i can go and play with the roughness roughness and reflection intensity and maybe to make it look more like rubber will turn up this roughness to say around 50. it's looking better and maybe turn down the reflection intensity maybe that's a bit too flat so let's turn down the roughness a little bit then we're getting some nice highlights and things and then if we hit it right with the right light so maybe i'm going to go look at what my lights are doing and grab this one and this is like using rim lights in photography and i just want to hit the sleeve see it creates this highlight along here and along the edge which is great for lifting um and creating some separation between a dark image or a dark garment and a dark background which i like to do a lot it's something i learned about using when i was doing physique photography and i'm finding that's a little bit too much so i'm just going to go back to my graphic and maybe turn this down to two and maybe put a little bit more light onto it you can move a closer you can change the angle you can change the intensity so here i've got set at seven maybe let's turn it up to ten that's maybe too hot but let's rotate this a little bit then we're getting some more of that highlight that i want and then just remove show so that we don't see the box and i know have another light back here but i'm going to leave it because i'm going to play it with it later but so that's how i did that logo the next tutorials we're going to look at how i created the snaps and how i had great difficulty because i still don't really know what i'm doing created these bungee stoppers so i hope you'll join me in the next one
