v8 RC4 - Override UVW

Corona Corona for Cinema 4D Issues
1

Hi,

Thank you for the UVW channel selection support in the Corona Bitmap, I’m glad the feature finally made it in C4D.

One thing though, it doesn’t seems to work :confused:

The Override UVW bool works, as when it’s true it breaks the UV Tag assigned by the position of the Material Tag. But the UVW channel selection doesn’t work and whatever channel is selected, it gets back to the first one. Even when I’ve renamed the channel 0 and 1. By the way, wouldn’t a slot to drag and drop UVW Tag be more a C4D-ish workflow ? Like the ones used in Material Tag for material linking and Selection Tag use.

I hope it can be fixed for the release, which is impressive feature wise, good job !

Attached is my test scene ( C4D R25.117 / Corona 8 RC4 )

Hi,

It still doesn’t work in 14.1, so we still can’t use more than 1 UV map per material in Corona in 2026.
