Hello everybody,

to rerender some channels I need only the faces towards the camera to be visible and "switch off" everything else in the rendering. I guess this is pretty easy, however I haven't found yet any option for that in the material or mantra nodes.

Can you give me a hint here?

on the Object there is Render/Geometry/Backface Removal property

or in the shader you can use Is Front Face node to control opacity by it

great, thank you very much!
