Author Topic: UV Padding and edge rendering when using Height  (Read 791 times)

Had an issue where I was adding some brushed metal with height detail to a section of my model which looked fine in Substance but the exported textures showed a non-smooth edge in Redshift C4D. The section with the brushed look was on a separate uv island but on the same UDIM tile. I tried both UV Padding options with no luck.

I discovered that the only way to fix it was to move the brushed metal section's UV island to a separate UDIM Tile. Once I did that, the edge looked correct in Redshift.

How much of a margin do you have between those UV shells?
I teach people how to use Substance Painter. :)

The original uv layout was like this.
