Why a flat shader behave as an emission shader Arnold c4d

[Simone_Cherchi]

I have created a shader in Arnold using a flat node, already before I give it any colour the preview of the shader seems to enilight the surrounding floor

If you don't want to see any bounced light, reduce diffuse_ray_depth to 0 or use a ray_switch shader.

Thanks for the answers, but if you are referring to the ray depth in the render setting then it would effect the whole rendering in my scene, is there a way to stop the bouncing only on this shader?

PS. in this moment I don't have a scene with this particular problem but it happened before, so I would like to find out how to solve the problem

[lee_griggs]

Yes, ray_switch.

Thanks!
