Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
I recommend using ureal engine for you real time renders. It sucks having to setup your shaders again but its the best free real time render. Also you get the added benefit of learning UE and putting it in your tool box. Another option would be Iray renders in Substance painter (but thats not free) -
Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
As far as I remember almost any render , gpu and games one too that uses ray tracing is unable to "round" hard edge/split corners same good as rasterized render . It's always been that way . Have no idea why. Always been seeing those hard edges, especially from a shaded side. -
Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
Hi, thanks for the suggestion about world space map, but I don't consider that to be a great workaround because the world space map doesn't show any of the low poly normals and gives a different look to what game art assets actually render like. I was hoping for a solution where you could use the tangent space map as the… -
Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
I tried it in Marmoset toolbag with ray tracing on a year or two ago and it was same as in Arnold for hard/split edges. But might did something wrong. Its a bit foggy now . Curious to learn if it works now? As of world space to tangent space normal map convertion you don't need handplane, you can do it in SDesigner baker… -
Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
@gnoop I can confirm raytracing works fine in Marmoset 4.06 with UV splits on all hard edges in the normal map, I just tried it to make sure and it's seamless without the Arnold bug. I also tested all soft edges and that works fine too, so you can pretty much set the normals however you like in Marmoset and it comes out… -
Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
I am also curious to know this tutorial to correctly render normal-maps. Arnold is my renderer of choice and i'm frustrated that we can't properly render game assets. -
Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
我想在这里留下我探索这个问题的最终解决方法,我查找了很多教程但是大部分只是指出问题,没有看到解决方案,包括上面提到的"教程",虽然我没看到这个教程,但是我大概理解他的意思.由于保密需求,我只能简单地描述我遇到的问题和解决的方式: 首先,我有一个在SP,Unity中显示正确的Mikk-T切线空间的法线贴图,我发现其在Maya 2020.4 Arnold4 CPU中渲染不正确.出现类似这张图片的黑边 由于模型面数太少且在角度大的地方没有断开UV并添加硬边导致的,你可以加面,重新分UV,重新烘焙一张几乎是平的细节(基本没有彩色部分)的法线贴图,遵循软硬边原则.… -
Baked high to low normal map has seams in Arnold CPU render on all hard edges.
Hi, I'd like to render my baked normal map in Arnold CPU, does anyone know how to get rid of all these seams? Scene file here if you want to take a look https://forums.autodesk.com/t5/maya-shading-lighting-and/arnold-cpu-tangent-space-normal-map-has-seams-on-all-hard-edges/td-p/10840311 -
Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
First thing to mention Arnold is bad rendering lowpoly with normalmap. Its made to render highpoly with detail normalmaps on top. I got the best results if i use the Arnold image node and flipped channels. I assume Arnold does use the same tangent space in all DDCs. It doesnt know how to deal with the tangent weighting in… -
Re: Baked high to low normal map has seams in Arnold CPU render on all hard edges.
I've followed the tutorial on the shader setup, but the issue persists. Could you point me to the tutorial about using object space + tangent space. Last time I met with Autodesk they actually fixed my Arnold bug with tangent space normal maps not rendering correctly unless you freeze transform, at the time he said Solid…
