Baking a texture without baked lighting?

[BenediZ]

Hello,
I'm trying to get a simple single Diffuse und Roughness Map from the input used in a VrayMaterial - which has a complex node tree.

Which is the proper way to get a reduced single map? (not with lighting baked! Just in order to replace the long tree with a single map).

When I try "render to texture" it renders with light (although "light" is disabled).

Thanks for help

You can go to the last node before the Material and right click on it then choose 'Render Map...' Specify a size and it will render it all down to one bitmap. It's how I reduce Substances since they bring Slate to a crawl.
