Using Fusion (formerly Fusion 360) python scripting, I am trying to generate some orthographic and isometric views as .pngs given a .step file.

This is what I have so far (these are 2 of the 4 images generated):

I am having trouble with two things:

• Programmatically changing the RGB color and the roughness setting of this CAD object
• Programmatically turning off the shadows on the ground and near the edges and bends of the object

I have attempted to solve both of these by consulting the docs, as you will see in my script, to no avail. Any help or guidance would be much appreciated. Code is commented by AI for readability.
