Roughness different depending of C4D color management setup

[yannverbeke]

Hi,

I use ACES with OCIO for color management. Depending if C4D color management is setup as Legacy (Linear sRGB) or ACES2065-1 I get a different result in my roughness (my texture is set to non-color data and goes via a gradient).

See pictures.
Any clue why that is?

I hear two stories : for Octane always leave C4D color management to Linear sRGB (legacy), and other say use ACES. The Octane Documentation shows how to setup up ACES (complex version) and suggests to setup C4D color management to ACES.

Thanks

Yann
