Hello!
We’re facing a problem here of transparant cars when rendering.

In the model everything looks okay, but when rendering it goes wrong (see attached images).
Does anybody know hat it can be?
Thanks!

Rob, try this:

1) Select all the vehicles in the scene

2) Choose the “Object Properties” option from the 3ds Max Design “Edit” menu. 

3) Check that the “Visible To Reflection/Refraction” property is set to TRUE.

It looks like this might be set to FALSE at the moment.

Let me know if this works.

Thanks!
This seemed to work!
Is there some standard configuration for this?
