Color managment issues after exporting layers in photoshop.

Hello everyone! I have some problems with color managment in photoshop after exporting layers from Substance Painter. The trouble is the pluggin export layers in custom color space, but I need sRGB color space in my prjects, and I can't convert space without changing any colors. Save original colors is important for me. Is there any ways to export layers in sRGB or convert space in Photoshop without color changing?
