Matte / Shadow material for animation

[yulianalazovskaya]

Hello, I am a new here. Great community. Excited to become a part of it. Learning everyday smth new. A silly question (please don't be harsh). It is a very blond question.

So, I am rendering an animation. V-Ray. I had to re-render only one moving object in the scene. Applied the matte / shadow material for all other object besides the ferry (so I will overlay it in the post-production software in the final scene.)

 

What should I leave in the Environment Map: the VRay material or Leave it Black?

 

Thank you very much

I am kind of confused with the question, you meant MtlWrapper with Matte surface on right?

and your questions was about if the environment will show in your alpha?

 

If so, while using VRay sky, your alpha will fine, now if you are using a dome light with HDRI, the you need to make it invisible.

yes, Francisco, that was the problem. But it is all good now. Thank you it was my first post, was too nervous i guess smh lol
