Assign Material is off by one row

[dan_grill]

When an object has more than one material, we go into edit mode, select some faces, then, in the Material panel, we select the material to assign to those faces only. In my project, I'm seeing the material ABOVE the selected material be the one to get applied.

For example, I have Materials A and B in my material list. If I select some faces on an object, then highlight Material B and click "assign", the one that gets assigned is Material A. To use the final material (B), I created an dummy slot below B, with no material in it. Click "assign", and Material B gets applied. My guess is that this is an array indexing error, like base 0 vs. base 1 arrays or something..

Hi,
We couldn't reproduce the issue on our end. Could you upload a simplified scene that demonstrates the problem so we can take a closer look?

The error was on an existing, very large project. When I tried to replicate it on a new, smaller project, everything worked fine. Blender version 4.2.4. Probably not a real bug, but something to do with the existing project when trying to use V-Ray. Thanks for the reply.
