Hi, I have been struggling with the obj mtl problem for some months. I have two results:
- Use the obj-mtl-importer in an script that load the files, apply the materials through mapping the color, transparency, etc and create an output image. It has the problem that can not be used in Paraview app directly (Only pvpython and pvbatch) and can not executed in parallel
- Use the steps in Paraview Ospray different results with materials. In theorie it should work in Paraview but right now the color are different. Only applicable to Ospray backend.
