I have some questions about nanite:
1. Nanite level detail in quixel
I downloaded one of the quixel bridge rock assets, once as a “nanite” level detail and once as a “low” level detail.
The texture sizes are 5mb for low and 284mb for nanite.
The texture difference is very noticeable, however on larger distances, would it even matter if it was nanite level detail?
2. Nanite on lower detail meshes
Is it useful to use nanite on a lower level mesh? From what I understand nanite is sort of an automatic LOD system that allows me to skip creating LOD meshes altogether? So if I would create a 30k poly mesh, can I just use that without ever worrying about lod? Can I just check the box for enabling nanite and will unreal use it with nanite?
3. Would it be a good idea to use a high detail polygon mesh with a lower res texture with nanite?
In the quixel example, is there a benefit of using the “low” texture with a “nanite” mesh? Because that would reduce the texture memory used by 56 times.
4. Selfshadowing
This is related to question 3. If I use a very high poly mesh with a very low res texture, what happens to the selfshadowing? is the way shadows are displayed on a mesh dependant on the texture resolution of the mesh?
