painter "auto" normal are always direct X

MmAaXx

Hi people

I made several .sbsar files in substance designer, due to pipeline my normal maps should be OpenGL.

When I import those sbsar in painter I noticed that the normal input is set to "auto".
'auto' is read as DirectX by default in Painter, no matter what.

The only workaroud is:
1- import the sbsar
2- fix the normal from 'auto' to 'GL'
3- save it as new material and export it (as sppr)
4- manually delete the .sbsar from painter shelf folder in documents 

substance player has not this issue.

cheers

Yes... this is a pretty frustrating problem. I wish Allegorithmic would get their eyes on it because it seems pretty nonsensical for Painter to assume my material normal is DX when I saved my Designer material as OpenGL and set my Painter project as OpenGL, I think it would be safe to assume by that point that I work in OpenGL.
Having to save out sppr (?) versions of all materials, and going through that process every time a change to the material takes place, is a major headache. That or having to trust that the individual artists will remember to manually go in and switch the "auto" to "OpenGL Normal".

Blehg.

Since Substance Painter 2.5 you can actually specify the normal format in the user data (via the color space) of your normal channel : https://support.allegorithmic.com/documentation/display/SPDOC/User+data

This way there is no need to change the color space in the interface of Substance Painter.

@Froyok  thanks for the reply,
 it looks like that .sbsar doesn't export userdata

It does export it, but it's possible that SD doesn't actually read/display it when you load in a sbsar. SP does read and use it for sure.

@Froyok Thanks, man! This works great.
@MmAaXx It's working for me in Painter (after a bunch of trial and error...). You need to write out "ColorSpace=NormalXYZRight" on your output normal node (not on the user data of the base substance, like I was doing).

Thanks a bunch, dudes
