Hello, forum members! I’m new to Blender. I have version 4.2. But the problem doesn’t depend on the version, because the same rendering result was in version 3.0.
I exported the model from DAZ 3D Studio via an obj file without the materials library.
2.
I created a Principled BSDF material for all meshes and connected the textures.
3.
In the render preview mode in the viewport, everything is fine and there are no problems.
4.
But when I run the render itself, I end up with an incomprehensible square grid on the nose and lips of the model.
5.
I tried applying Triangulate faces to the mesh, but it ruins the UV maps and her face becomes a disaster.
6.
I tried doing Merge verticles by distance - not a single duplicate vertex was removed. The mesh is initially “clean and well-groomed”.
7.
Tried to apply the “Smooth” modifier - does not help. The result is the same - a whitish mesh on the lips and nose.
8.
Tried to apply “Clear seams” - did not help.
Please tell me what the problem is and how to fix it?
Thanks in advance!
You could try… but you’re a new user here, and there’re some limits to what you can do atm.
And thought the scene would be great, a simple screenshot of the material editor can be usefull as well.
The Texture “g9feminine04_head_nm_###.jpg” should be set to ‘Non-Color’ and not to ‘sRGB’.
Also, the NormalMap node should be set to “Tangent Space” and not to “World Space”.
And there’s also a CustomNormal layer in the mesh… you might want to remove it (Properties >Mesh > Geometry Data > Clear Custom Split Normal Data)…
It makes the mesh looks strange
Thanks for your explaining! Now “net” disappear. But in “Tangent” mode here is seam between vertex groups. Line with changing shading on shoulder. How to fix it?
Also I have one SSS (Sub Surface Scattering) texture, but I can’t find the way, how I can plug in it to shader. Where is input for SSS color map? And I’m not sure if I connected “Specular” texture correctly?
Yes. I did it with all materials. When I plug all SSS colored textures to “Radius” port, my PC is stuck, when I press F12. I have weak “1030” Nvidia card. Render even not started. I was forced to kill “Blender” process in Task Manager. Now I rendering without SSS maps.
I don’t know if the sss texture is done specifically to Cycles, but as it’s a color, you should plug it in the ‘Radius’ socket, and change the ‘Scale’ and ‘Weight’ until it looks correct.
About the seam, i cannot see it from here… Your scene didn’t had the Textures in it, so I can only see the geometry and the material setup… not really a rendered image.

I was forced to kill “Blender” process in Task Manager. Now I rendering without SSS maps. And with seam now all alright. I’m just forget to swap Normal map on “non-color” in one material. Thanks you all for helping!
P.S. Here is final render:
But barely-visible square-polygonal net on neck and shoulder still exist.
