Help with toon shaders rendering

[MechNuggets]

Hey guys,

I have been playing with toon shaders recently and I have some trouble rendering it to look like in the sculpt or paint room

This is how I would like it to look (Flat shading, hard shadows)

 

This is the closest I can make it in the render room but there is still a lot of soft form shadows and a lot less contour lines than in the sculpt or paint room.

Iv included my shader and rendering settings.

 

I know I could just screenshot from the sculpt room but I would like to render it at a bigger resolution with an alpha channel.

Does this have anything to do with the HDRI im using or is it because of the shader settings?

Thanks a lot for any help you can provide

 

Cheers
