Hi everyone,

I have some questions about rendering with PBR in H13.

On this image you can see black dots, they are displayed as NaN pixel in Nuke, and I have no idea why they are here… I found a subject on odForce, http://forums.odforce.net/topic/18115-reflection-with-spot-mantra-render/, [forums.odforce.net] I did what Green-Man said, but it didn't solve the problem. There were no GI on the scene. Does someone know how I can solve this ?

Another question :
Does we still need to power the color by 2.2 for the gamma correction to be effective in a texture ?

Thanks a lot,

Tom.

try dropping the Color Limit from 10 to 3.

Mantra/Properties/Shading

Edit: there is also Nan profiling in Statistics/Vex Profiling.

You mean Diffuse Limit ? Because it was set to 0 for this scene.

Thanks for the “Vex profiling”, maybe it will helps !

Color Limit in Mantra.

Woups I'm sorry I was looking in H12.5 (it was in the PBR tab)

Thanks a lot !
