Finally.
The new Substance is here. Works really well.
Algorithmic rewrote the whole plug-in. (Bug fixing, new features, all new code in the background.)
The color management problems are still there if you want to render with mental ray.
I just fix it. 🙂
The new PBR workflow is really great (no color management problems).
You can download the plug-in here:
