I tried this render about a 1 1/2 yrs ago and had to
try it again with the current blender cycles 2.91.0.

File from the internet.


Is this the new render? or the old? What differences have you seen?
Are these your models?

This a new render. The old render is somewhere buried in this
forum. This are not my models. You get the original free scene
from this website that has the Download link and just click
where it says “Download” on this site :
