I did a search but didn't find anything on this. My problem is that when I export a scene from Blender (2.59) to Octane (2.49b) with exporter (1.0.9 or 1.1.0), almost all materials turn into glossy materials. In my current project all but one material turned glossy. Most of them then need to be changed back to diffuse one by one in Octane. This is a problem when there are tens of materials.
I just tried exporting the same scene from Blender 2.49 to Octane 2.46b, and maybe half of the materials turned glossy.
In the Blender exporter all materials are glossy as default, and I tried changing them to diffuse in the exporter but this didn't make any difference.
Any ideas what to do? Thanks.
