It saves any color as black. I went back to Blender 4.1 to prevent this. But its better to go to blender 4.0 as a bug with the compositing will give you trouble in the future. (during the bubble exporting segment)
that is SOOOOO not intuitive! I only just saw this, because it's been bugging me.
(was also looking for the inverted option that I remembered was in there... helps if I'm on the right drawing tool :D )
Update: this has since been fixed, and colors can be added as before.
Re: inverted option - can you clarify? Do you mean flipping foreground/background colors like here:
In which case there *is* a shortcut, but it doesn't really work well, so the best thing to do is assign your own. Right-click on the two arrows in a circle, and assing/change chortcut to something that makes sense, but isn't obviously something that Blender would use for another operation (eg: X)
Or did you mean like, switching from draw to erase? In which case, this is actually easier - hold down CTRL while in draw, and it will switch to erase.
No.. I'd found it... I was talking about the inverted fill :D Once I switched to the fill bucket, I found it :D
