Transfering UV to Vertex Color doesn't work. #27

It seems that transfering UV to Vertex Color has a bug. I made a simple plane and subdivide it , and transfered uv to vertex color. The result seems broken.

I used Blender 2.80.75

Thanks for spotting this. I was able to reproduce it in Blender 3.3, and it seems to be a rounding error. I think I shall have to clamp values to 0-1, as it looks like the values are wrapping when they are very close to the edge. If you scale the UVs down very slightly, this problem won't occur, but I will try to fix it for the next release.

The purple tone is simply because the blue channel is filled white. You can fix it by selecting only B under active channels and hitting Clear.
