RENDER A MESH STEP-BY-STEP:
1. copy "template_lazy.py" to your preferred local folder
2. In "template_lazy.py":
- change "mesh_path" to your desired mesh path
- change to sys.path.append('path/to/BlenderToolBox/cycles/')
3. run "blender --background --python template_lazy.py" in terminal, then terminate the code when it starts rendering. This step outputs a "test.blend"
4. open "test.blend" with your blender software
5. in blender UI, adjust:
- "mesh_location", "mesh_rotation", "mesh_scale" of the mesh
6. type in the adjusted mesh parameters from UI to "template_lazy.py"
7. run "blender --background --python template_lazy.py" again (wait a couple minutes) to output your final image
