In Blender 2.8 how do I change the settings for the workbench render properties via python? The settings for the workbench render, not a viewport. For example if I manually change the lighting to FLAT, then the info panel reflects the command
bpy.context.scene.shading.light = 'FLAT'
but when running this myself it says that 'Scene' doesn't contain the attribute 'shading'. Same result if I directly access the scene object through bpy.data.
In the same render settings panel, in the 'Film' dropdown I can successfully change the Alpha Mode with
bpy.context.scene.render.alpha_mode = "TRANSPARENT", but the settings related to the render engine have no such access that I can find.
