I'm trying to add a little darker shading to Thomas Ruth's A306 vc panel, but it shows up as a black texture. I'm saving it as a DDS DXT5, same as the original, and no alpha. My process is modification in Photoshop. Save as 24-bit BMP. Convert to DXT5 with DXTBmp. I'm an experienced painter but this has me stumped.Thanks for any help.

Whoops, I think my DXTBmp needed updating after all these years.
