  uv_mapping not working? (Message 1 to 3 of 3)

Am I correct in assuming that uv_mapping is not working correctly? I may 
have overlooked something, but I did not find a reference about the 
subjetct.

I ask this because I have a scene with uv_mapped image_maps which render 
correctly in v3.6, but are totally invisible in v3.7. If I switch off the 
uv_mapping parameter, they become visible again.

something is evidently amiss here, though in my tests I don't get totally
invisible maps (nevertheless it's not working as expected, either).

please post minimal example scene.

Here is an example.
In fact, the image appears to be visible, but it needs scaling up to cover 
the object again, which it doesn't need with v3.6.
My initial scene was seen from much farther away, so it looked like the 
image_map had disappeared.

Hope this helps.
