Release is uploaded here:
New shader GUI.
fixed various physx things.
Added note in physx modifier about importance of pivot.
added basic spotlight support. with shadows.
more error handling.
new sample scene.
Diffuse texture works (just make sure you use mapping channel 1).
Today has been a great day for the exporter!
I have fixed many bugs, and Konstantinos Mourelas has been working on the shader.
We also sorted out a important "bug" that had to do with the physics objects.
The pivot NEEDS to be centered on export for it to behave properly.
I've added a note about this in the modifier itself.
I added spotlights too, they have shadow support.
The exporter is stable and works great, very fast too.
It's a blast to create something in 3dsmax, then 2 seconds later it's inside maratis.
I will release a new version tomorrow after we've fixed some more stuff.
