Vray rendering with noise and splotches in shadows

[Anonymous]

I'm having a problem with a very simple render. I imported some FBX objects and applied a white v-ray texture to them but the shadows are rendering with blotches and noise. Image below. This only happens on certain objects and not on others. The ones that are affected in this case were downloaded from Sketchups 3d warehouse.

I'm using:

• V-Ray Next, update 2.1
• 3ds Max 2020

What am I doing wrong? Thanks!

Check the normals in your geometry and also coplanar polygons.

If you are getting 3DModels from 3dWarehouse, this will be very common those 3D Models.
