check your camera shape does have any image plane? if the image plane is miising or any shader missing then you have this issue.

Can you screengrab the scene in Maya with a render please showing render settings, shaders etc? If you can, post a simplified scene too.

Hi @Raju S Thanks for the answer. I do not have image plane in my scene and I not have missing shaders. Thanks a lot.


Hi @Lee Griggs In my using ai standard shaders from Arnold. Al my texture have been created in Substance painter and I am working with 2k and 4K texture size. I am working in meters and all my objets are real scale. The points i have in my render are in some frames not in all and there is no always in the same positions.

Thanks

Which AOV has this noise? Specular? Diffuse?

Red could be a texture error, but they don't look all red.

Did you check the Arnold log?

What version of MtoA? What shaders? Any custom shaders?

Hi @Stephen Blair It is en the beauty pass. I have not rendered AOV´s. Good point to render and check it.

Yes there are some white points too. How can i check the Arnold log?
I am working with Arnold 3.0.1.1 and all my material are aiStandard surface. The textures i did in substance painter are the base color, roughness and normal maps.

Thanks for the answer.

Are you use emission and transmission or mesh light in headlamp car?

In render settings, clumping palette, set indirect clump value to 1.
