material loading in blender_scene_render.py

[shivanimall]

Hello, wondering why is this commented out and not used to load material for the object:

https://github.com/ztzhang/SoundSynth/blob/master/online_synth/render/blender_render_scene.py#L263

and likewise material is read in gen_sound.py via ReadMaterial function but values set are not used.

Thanks.
