Hey i just upgraded to the 2023.11600. I noticed the selection 32 bit float RGB format is gone. Is that normal? Am I suppose to select 32 bit float RGBA and just masked the alpha channel now if i want the 32-bit float RGB?

I have the same issue. When using a velocity feedback in the Nvidia Flex actors, I get an error saying it must be a 32 bit RGB, not RGBA, and there is no option on any TOPs I’ve looked at to use 32 bit RGB. Only 11bit RGB (positive only).

Yes, the GPU never actually allocated 3 channels worth of memory, the alpha was always there, just forced to 1. So I just removed that format since it wasn’t really useful.
The Flex part is a bug though, which will be fixed.

The error in this case is wrong - it’s actually a 32-bit RGBA texture that’s required. I’ll fix that.
