Nanite Tessellation + Vertex Painting with Height Lerp | Unreal Engine

[@HojDee]

Update: in Unreal Engine 5.5 support for per instance vertex painting on nanite meshes has been added!

[@suraj.1889]

Someone in LinkedIn pointed that it's a bit different from vertex painting, terming it as mesh painting. I hope you make a video on this to dismiss doubts.

[@HojDee]

@@suraj.1889 I'll check it in the coming days. Thanks for mentioning this

[@tylermadigan7631]

Reminder: If you are not satisfied with the quality of the "Displacement", you can change the compression of the ORDp maps to "Vector Displacement Map (RGBA8)" and then change the sampler type to "Linear Colour" in the material, but don't forget that this will increase the memory overhead.

[@HojDee]

Thank you 👌

[@LoganPinney]

Brilliant response. 👏

[@quadro_11]

THX!!!!

[@ZacDonald]

If you're using a packed 3 channel texture like ORD with the default DXT1 compression in UE, put the displacement in the green channel and use a levels adjustment on the green channel to clip out any unused info at the min/max ends of the range. Can save memory and maximize the quality. The green channel has 1 more bit of data and any unused space in the levels view can be put to better use.

[@UriahGnu]

Finally a video where the result looks as good as the thumbnail! 👏Bravo for that.

[@hardath6455]

This a very cool but per instance vertex painting is still not working on nanite meshes, so it'll work on your unique plane but never on a modular set of walls. In this case vertex paint will repeat itself on every instance of the aforementioned mesh, creating repetition, which is very counterproductive because vertex painting is used to negate repetition. Once again, very cool results, but very not production ready. For similar results on ground just use the landscapes tools and landscape layer blending system (with height selected in your layers' blending modes). vertex painting is kinda useless unless you using it on a unique mesh like a hero asset or to assign specific texture sets to architecture. But still, very cool video :P cheers

[@HojDee]

Thanks for the comment :) Yeah I know. I mentioned it in the video that becaise we're doing it from the modelong mode, it affects the source mesh. But using it and playing around with it is still cool. It's not production ready for games, but for cinematics we can use it. Looks great.

[@quartermaster2809]

this is really awesome. I think its a bummer that vertex painting nanite meshes can't be done per instance, since that way so much variation would be there in a large area and less repetition. Hope it is something that gets added in future

[@HojDee]

Yeahhh. I hope so. It will unlock so many possibilities!

[@picnawodefotomontage]

This looks amazing! Is it costly in any way, though? I didn't really use tesselation nor displacement in the past.

[@ABentPaperclip]

nanite is very cool, but no vertex paint per instance is a total dealbreaker imo

[@HojDee]

I mean nanite doesn't need traditional vertex. But maybe they'll add it in the future veraions. It's still great for cinematics. And the height blending can be used to create different variations with material instances

[@ABentPaperclip]

@@HojDee i see a lot of people saying things like this- of course nanite needs traditional per-instance vertex painting. being able to displace a heightmap doesn't magically make the utility of per-instance vertex painting disappear. If you don't have that feature, all of those amazing highly detailed meshes end up being copy/pasted around the game- you can already see it happening with lower quality UE games that use megascans "hey theres that log again". what good is all of this extra detail if it's so repetitive? say you have a rock you want to put some moss on a very specific location, so you can't rely on RVT or distance fields. With nanite you'd have to make another copy each time. It's not a real solution, you can't ship a game with 90 slightly different copies of the same rock.

[@HojDee]

@@ABentPaperclip you're right. Let's hope they make it work like non-nanite meshes.

@@HojDee I have not been able to get it to work. I think the sampling from the RVT doesn't compensate for the visual mesh displacement. I can't find any documentation. But I'm unsure why they aren't playing nice.

[@JESSJAMES1886]

Hi Hoj, I have a problem. I follow your video step by step in detail, I check every adjustment you make to the millimeter, but when it comes to tessellation, my material looks peaked from close up. It's kind of out of focus. It's a shame I can't send you a photo of how it looks because to you it seems that the tessellation looks perfect, but to me it looks like mini-mountains with spikes everywhere. And it doesn't matter if I lower the magnitude because it doesn't look good either. I'm creating a photorealistic first-person game, and I'm afraid that the environments appear to look good, but that the player sees this error as soon as he gets close to the ground. I don't know how to fix it, really, could you help me? I hope I've explained myself well, thanks for your help.

[@JESSJAMES1886]

Also, when it comes to painting Vertex, it doesn't suit me.

[@JESSJAMES1886]

Ok, My problem was the meshes where I was executing the material. On a created landscape it does let me use the modeling, but on the ground asset of the star content or on the actor creation plane, it doesn't let me because of the vertices, I imagine I'll have to export to Blender and make more subdivisions. My intention was to do this on walls and make the mix of nanite materials and with tessellation on more surfaces apart from those of the landscape. I'll keep watching your videos to see if I can find it. Thanks.

@@JESSJAMES1886 hey Jess. How is ot going? Did you manage to fix the issue?

@@HojDee Hello! I don't want to be annoying. I finally solved everything, but I was very confused when I saw how the tessellation worked well in landscapes, and it didn't work well in meshes like walls and floors, I couldn't solve that. And I have understood about painting vertex that it only works in small spaces and in landscapes thanks to your videos. I'm creating a photorealistic zombie game, and I feel like I'm a very slow learner.

Still I think its affect on displacement map color not nanite displacement Magnitude if I'm not wrong which its mage huge difference in details specially on high values of displacement Hight, am I wrong?

did you use the displacement scaling magnitude? I mean it's under the nanite tessellation section. So it's affecting the tessellation, using the data in the texture. But the texture is not being affected like when we multiply it.

For example I mention that I have a material nodes playlist. I can't explain each node in every video. If anyone is unfamiliar and wants to learn more, they can refer to that playlist. Same goes with enabling nanite displacement. I shouldn't explain the basics of enabling and using it in every video. It's a waste of time for both the viewer and me.
