OK, thank you for the explanation sir.

PS for textures: 8000-8000 is not efficient

Use :
512x512
1024x1024
2048x2048
4096x4096
8192x8192

With Posers texture caching (selectable in General preferences, Render tab) and with the texture set to quality or crips, Ram consumption stays pretty low as Poser only loads what is required to render the buckets is working on.

I worked a lot with 8192x8192 single map textures.
And at render time, Poser only has to load and read one map.

FYI; the texture layout for the PoserPro figures is a very good example.
