(3DS Max Vray) Ceiling going black in render - Help

[crislouisnarceda]

Hello guys.

 

This is my first post on this website and I'm eager to explore the wonderful creations of this community.

My friend has an issue with his render. The ceiling of her visualization is black and it doesn't reflect light easily. However when I separate the ceiling solid from the main model up to expose the black side to the environment, the texture is visible.

 

To get rid of the black void, I tried creating the material again, increased reflections, and I recreated the ceiling. But it still wouldn't reflect any light.

 

A low quality rendered image of the model is attached. As you can see, the ceiling appears to be made of vantablack. Could anyone help me please?

 

Thanks in advance.

Right Click on the object; select "Vray Options", make sure the object is NOT matted and its alpha contribution is set to 1.0

Check the normal of that mesh or if there is double geometry.

Also, are you using a simple shader or you are adding dirt material to it??

Dirt material create similar effect when you have double geometry.
