Hello,

In Rhino 6 I used:  
renderWindow.GetAdjust();  
renderWindow.SetAdjust();  
to change the gamma settings of the material preview

This is obsolete since Rhino7  
Probably I should use Rhino.Render.LinearWorkflow (??) now?  
But how can I use it?

Thanks,  
Márton

Not sure how that works for material previews. Why do you need to change the gamma setting for material previews?

I think we need to ask @andy to figure out how that is supposed to work, though.

As I was thinking about it I realized it is probably better to handle the gamma correction before display.

So I use now a Adjust.gamma free solution…
