I've been trying to follow the tutorials of Lee Grigg's PolyMesh To Volume:
However, I am encountering some problems and I hope some of you could help me with this...
-Whenever i convert my polymesh to volume and I render it, this becomes really noisy and greysh(even though I set the color material to full white), while Lee's one is completely white and doesn't show any noise whatsoever..
-The main problem is, whenever I assign the displacement to the model and I render it, I encounter the problem shown in the image below(The mesh is open on the mouth , but before applying the displacement it renders just fine, I even tried with it's dynamesh version[closed] and still it gives me the same problems, black spots, but just in different areas,I even tried with a really lowpoly mesh, the problem remains...)
-The step just after applying the displacement is the one to apply a texture to the displacement, I tried applying a Noise Shader, but it covers the entire model, while Lee's one affects just the back of the head, how is that possible? Does anyone know what texture he used exactly? Even because he's effect looks really nice with it...
I also attached my Maya scene. Hopefully someone could have a look and help me out.
-The open mesh is the visible one once you'll open the file, if you want to give it a try with the closed one in the outliner is called "Dynamesh_geo"
-There are some shaders in the scene, the one you want to use(which is already applied to the mesh anyway) is the one called "PolyMeshToVolume01"
