i am quite new here.
I understood, that it is not possible to export texture of my .obj object exported by micro exporter, ok.
So i can somehow export just .obj without texture and with camera maping, so i can put the final render as a texture.
Can i somehow render just "diffuse pass" without any shadows so i can count all the shadows and GI in my 3dsx Max - Vray?
Yes. Plug In 'Render Layer' to your render node.
On the 'Render Elements' tab, tick 'Surface Diffuse Colour'
Set a path for 'Extra output images' in 'Sequence/Output' of your render node. Hit 'Render All To Disk'.
This requires the Professional version of Terragen, just so you know.
