After several hours of trying I realized that the problem is more complicated
for commercial models with textures.
Even when using the obj exporter from 3dmax the obj file in Octane is not recognized in matters of texture.
Hundreds of models from several providers are useless in Octane while on other apps are loaded smoothly.
An example is models from CG AXIS
99% are not loaded and I cannot fugure out which property in the mtl file causes the fault.
Even deletng the map_kd to map_d does not work.
For both octane standalone and plugin (archicad in my case) textures are replaced with rgb
A demo file can be downloaded from here
https://bit.ly/volume67_free_modelThis should be consider a bug for octane as just the geometry is half the way for complete, proper importing.
Please take in consideration this factor for the next updates
