In the middle render window you see a Chesterfield armchair in DARK brown leather. To it’s left and further back are two armchairs with the same material and texture that appear as LIGHTER brown leather. All chairs consist of parent objects with children being their parts. Each part is assigned a material and texture. (so it’s actually parts of the chair that are the same leather)
See the outline window to the right. The upholstery in both chair types is identical: material and texture.
I had at some point attempted to lighten the leather using the color menu under the texture, but in the end I only have this one texture applied to both.
Q1 — Any ideas what maybe happening?
Q2 — In addition the upholstery in the armchairs in the background has a cloudy patch “on” the material… There are no double vertices, no mapping (intentionally), no other texture slots than the one leather. What can be happening?
Q3 — I see people in the forum checking the data structure in such cases using an “oops” window. Where is that?
