Gloss map offset

joebount · Feb 2015

Hi guys,

When we try to export a gloss map at work (pbr parameters or our own (gloss as gray) we suffer from the map being offset by roughly 30% to the right).
The map export fine as RGB though...

Is anybody else having the same issue ?

EDIT : apparently, it only happens when we use TGA, tiff is fine. Any idea ?

Might be sRGB color profile?

a physical offset in the texture ?

This is weird. It might have something to do with what we store in the texture header. At some point, Toolbag 2 would flip TGAs coming from Substance Designer for no apparent reason, all other format were fine.

Still have the same issue

I'm afraid the issue is on Toolbag side, not Designer.
A workaround meanwhile is to put a gradient map node just before your output node to be sure your export as RGBA and not Grayscale.

Yeah, the gradient map works but the issue is not in Toolbag : if you open the map in photoshop, there is still an offset... really weird...

Which version of Photoshop and Designer are you using ?
I just opened a grayscale TGA in Photoshop CS5 (12.1) and it appears fine (exported from Designer 5.0.1).

We are using the latest versions of Painter and designer and Photoshop 12.0.5. The issue is with Painter. If you want more info, I can PM the email of the person having issues with it right now if you want.

Yeah, send me a PM and we will enter in contact for additional details.
