Imported Substance Designer material has only Red channel in the baseColor texture.

Hello,

When I import a substance material (.sbar), my basecolor texture only has the red and alpha channels.

However, in the content browser, the texture appears as if all the channels are there.

I’m using Substance 5.5.1 and UE 4.15.1

Did you solve it?

Yes and No. I upgraded my Substance, then resaved with the new version and it fixed the problem. Maybe it was a bug that caused the problem, maybe my file got corrupted somewhere along the line.
I think I went from Substance Designer 5 to 6, but not sure.

Hi all,

This is still a problem currently but there’s a simple workaround in Substance Designer.

Just convert your grayscale information to sRGB before feeding it into the base colour output and this will fix this issue.
