Make an AWESOME Wireframe TRANSITION Effect! Blender Tutorial

whoa okay that was that was pretty cool hey everyone it's steve here from CG geek and today we'll be taking a look at how to create some awesome looking wireframe transition effects in blender so after countless requests on how I did the wireframe transition effect in my intro as well as in other videos now that I've posted I've decided it's high time that I did a tutorial covering this effect and not with blood or two-point-eight it's easier than it's ever been before because we can use Evie and do it all in real time so I hope you guys are excited for this video all you have to do is download blender 2.8 to be ready to go and let's jump right in I [Music] also want to quick thanks Gil share for sponsoring this video with skill sure you can get smart quick learning anything you

in blender 2.8 we're gonna be using the low poly character that we created in my previous tutorial and if you haven't created this character yourself I will include a free download link in the description for you guys so you can follow along exactly with this tutorial and if you're interested in any of the other finished tutorial files on the channel you can get all the downloads over on my patreon page for just three dollars a month and get access to everything I've created on the channel so what wouldn't be doing with this model is using a combination of different modifiers and key framing to get the transition while your frame effect coming across our model to reveal it so hope you guys are excited because I'm using some modifier and stuff that they haven't used at all on the channel yet some pretty new stuff so starting off what we don't have to do is first apply a vertex group to the model that we want to transition on so I'm just going to tap into edit mode and select our whole character here and then over in the sidebar you're gonna want to be in the object data tab right there and just go plus on the vertex groups and then assign the model to that group you just made and that's what we have to do for that now what we're gonna be doing is we're gonna have a separate object controlling the vertex group intensity on our model so we'll go ahead and add an object for that now I'm just gonna go shift a and I like to use an eco sphere for this so go ahead and add mesh eco sphere and we'll just scale this up quite a bit as you can see right now this model is affecting these shadows and stuff on our scene we don't want that so we're just gonna go over to our object data right here and then under a viewport display we're just going to change it from textured to wire okay so when a scale add up to be about the same height of our model there so then what we're gonna do is I'm going to grab our mesh here and we're gonna go to the modifiers tab and we're gonna add a new modifier this is going to be the vertex weight proximity modifier so you might have never used this modifier before but lucky for you you're gonna get to try it today and it's a really cool modifier so what you're gonna start off by doing is under the vertex group here we're gonna choose that group we just created and then I'm going to choose the targeted object that we want to be editing the vertex group with so that object is going to be the ICO sphere that we just added in there and with that set I like to change the distance from object to geometry and now we can already see this working if we jump over to weight paints you can see that the area of the mesh that's closer to the anko sphere has no vertex weight applied to it and the area on the opposite side is full so if I was to grab our ecosphere here and move it a bit closer if we went back to weight paint mode on our object you can see that it's editing the amount of weight paint on our object and that's exactly what we want now what I want to do is I want to affect the lowest and highest to kind of pull that value in to be a tighter margarine and as you can see as I edit these values we kind of take away the fading as' and make it a sharper cutoff between the fall-off of the weight paint and no weight so what I want to do actually is I want to get the lowest just a little bit of a higher value this basically inverts it so we have everything that this area is touching with the ecosphere having the weight paint and everything that's not touching no weight paint and what you can do is you can take these values down a bit to bring it a little bit closer to your ecosphere so I'm gonna go ahead and set the highest value to one and the lowest to one point one and that just gives me a good amount of radius around our IQ sphere affecting the mesh so I'm just gonna kind of move our ecosphere now so the line of cutoff is right around the middle of our mesh just so it's kind of easy to work with now and I'm gonna grab our mesh here and go to weight paint and you can see that that's that's pretty good we can move it just a little bit more alright so now it's time for the wireframe effect so with our ecosphere affecting the vertex group what we can do now is if we grab our mesh here and add a new modifier the wireframe modifier let me see where it is right here at the bottom and you can see that makes a very cool wireframe of our character here and I'm just gonna collapse that down for now we can change the thickness a little bit if we want to do and you get just a nice sort of wireframe effect there I'm gonna go with 8.03 and now do I have the vertex group effect where the wireframe is basically visible and where it's not all we have to do is under the thickness we give that the group as well of the same vertex group as being edited by the eye Chris fear and you can see now that when I move the eye Chris fear it kind of appears and disappears with it now the other thing I like to do is I like to cut the ecosphere in half so I'm going to tab into edit mode rotate it in ninety degrees so we have this line straight down the middle and now I can just hit that button right there so I can see the vertices behind the mesh and now I'm just going to tap in edit mode and delete everything on the right side there and then tab back out of that mode so now with this mesh you can see as I move across is making it invisible and then making it appear behind it this is working but it's basically working opposite than what I want so now all you have to do is grab your wireframe and if you hit that little button there it inverts the group and now you can see that everywhere is touching it's visible and as it moves over it's invisible behind it so pretty cool and then this can also be affected the amount that's visible can be a did by our vertex proximity here so if I take this down a little bit on both these values you see the amount of vertices that are visible as it moves over goes down and that's pretty cool another thing you can kind of play around with is if you change it to edge or face you can get some different results you might want to go with face as this will give you a little bit more wireframe visible in your animation so with this setup you can see it's already quite a bit of fun to play around with and if I was to animate the ICO sphere I could have the wireframe moving over this mesh but we also want it to be revealing the object underneath it and not just showing the wireframe so what you gonna do for that is we're gonna grab our mesh that we have the wireframe applied to and we're gonna hit shift D to duplicate it and on the duplicated one you can see up here we have two of them now I'm just gonna turn off visibility on the first one so it's not getting in the way by hitting that eyeball there and not what I can do is I can delete the wireframe off of our second mesh here and instead of using the wireframe we're going to use a new modifier and this one is going to be the mask modifier so go ahead and add the mask amount of fire in and just grab that vertex group as well now the mask modifier there you can see that it's already making portions of our mesh hidden now the thing is this has to be right behind the wireframe so what I like to do is just create a separate ICO sphere for this object as well so I'm just gonna hit shift D and duplicate the ecosphere and for this one I'm gonna go back to our mesh now I'm just gonna change the vertex group from you the first ecosphere to the IQ 0.001 that we just duplicated now you can see as we move it over it is making portions of it hidden but it's not working a hundred percent yet because we want it all to be invisible to start and then visible as it comes over all I have to do is hit that button to invert the mask just like we did on the wireframe and now you can see that if it was moving over it's making it visible but you can see you as it moves over it's also hiding the mesh behind it as well just like the wireframe to fix this what we want to do is grab our mesh here and just increase these values to be something quite a bit larger now so I'm gonna take these both up to be about a 1 and then you have to move this eye crease for your back a bit right around here or so but you can see as it moves over it reveals the mesh and that value is large enough that nothing is being hidden now behind it if I was to move it even more you would see it start to hide again but that is plenty to reveal our whole mesh so that's all we really have to do so now what I'm gonna do is I'm going to turn on the visibility of our wireframe and I'm just going to kind of position this eco sphere to be following behind the wireframe so right around here looks like the good amount of mesh visible behind that wireframe and now you can just grab your eyes feel their shift grab the one with the wireframe and go ctrl P and set parent to object so now all we have to do is animate your wireframe ICO sphere here and the one giving the visibility to it follows behind so to animate this effect now we're just gonna pull it over to the edge so nothing's visible we're gonna go ahead and hit I and hit location and then on our timeline here you can see we have a keyframe right there I'm just gonna jump to about frame 100 will grab this along the x-axis and just move it until everything is visible it's a writer on there looks good and then I'll hit I and a location one more time and now you can see if we were to play this back as the moves over our mesh is visible if you want to happen a little bit slower you can just grab that key frame there and pull it along your timeline I'll give it two hundred frames and you can see that as it moves across we have the wireframe with the mesh appearing behind it I'll go ahead and move this all the way to the end of our timeline there just so it happens even slower and then what I like to do to kind of finish off this effect is grab that wire frame and give it its own material so over on the material tab here I'm gonna go ahead and give it a new material I'm gonna delete the default one there give it a new one and this one I'm gonna choose the surface to be an emission shader so giving it an emission will kind of make it glow and kind of reflect off the mesh behind it give me a really cool look I think so what want to do is when we give it kind of a yellowish color although you can also do a blue as blue is kind of a cool electric sort of color so I think it'll go blue and then just crank the strength up to be something like three or four and if I unselect everything go into my evie settings real quick up here and enable bloom just to make the defect even cooler you can see that as it moves we have the wireframe appearing with the mesh appearing behind it and if you want the message to be a little bit closer all you have to do is grab it and pull it in a little bit more and it will still follow that mesh that is parented to so you can see here is the effect the wireframe is coming over it the mesh is becoming visible and as it comes across the whole object is revealed and the wireframe goes with it and then disappears at the end so pretty cool you can see that the wireframe is still a little bit visible there so we probably have to move this just a little bit further along the x-axis to make that 100% invisible and new keyframe but there it is guys I hope you've enjoyed this wireframe transition effect tutorial is something I've been asked to do a lot like I mentioned earlier and it's really a cool effect so I should have done it a long time ago but not with blended 2.8 and it being able to all be done in real time with evey it makes it even cooler so that wraps up the tutorial guys I hope you enjoyed creating some a wireframe transition effects if you curious how I did it in the beginning with the live footage basically the exact same method only I saved it out as render layers so you would just select the wireframe and turn off the visibility of everything else render this out with just the wireframe and then you could do the same thing with the mesh and not the wireframe render that out and then just overlay those on your video to make it look like you appeared using it as a mask to kind of reveal the live footage underneath pretty simple stuff but I hope you enjoyed this tutorial created some cool transition effects and had some fun along the way if you liked the video leave that thumbs up if you want to download anything you've seen on the channel you can do that over on patreon for just $3 a month and I'd like to give a big thanks to Skillshare for sponsoring this video you can check them out with the link in the description and get those two three months that's gonna do it guys I will see you in a future video bye bye

This was cool, and provides some ideas for other similar effects.
