Thanks guys, that's the one.
I'm used to being able to set the colour space afterwards with the VRay Bitmap node, so I didn't even think about changing it at the import stage.

[Max] I need help! / Roughness from Substance 3D Painter [solved]

« on: 2024-02-23, 09:52:57 »

Hi,
I've recently started using Corona, having come from VRay.
When I attach my Roughness map exported from Painter (PBR Metallic Roughness) with a Corona Bitmap node to the roughness slot of my CoronaPhysicalMtl, my object renders far glossier than it looks in Painter, or than I'm expecting. I can get round this by using an OSL Bitmap Lookup node, or by pushing it through a Color Correction node, but I feel that that shouldn't be necessary.

What gives?

Additional info:
I set the Corona Bitmap node to Raw (this doesn't make any difference in the render and appears not to in the Slate preview image).
I know the difference between Roughness and Glossiness, and which of the two I'm using.
