Hi,
For a school project I have made a FLIP sim that enters the scene when a door opens. The project has been 3Dcamera tracked, matchmoved and model-built to sit in the shot nicely. I am wondering what the pathway would be to render only the visible sim once the door has opened to let the fluid enter the scene.
Would there be a material I can put on the door which will act as an alpha that I can use the original plate and as the door opens it is only the exposed sim that renders?
I don't know how to set this up, haven't done many complex renders at all.
I hope someone can help or at least point me in the right direction.
Because my working file has a lot of imported objects I have just uploaded a still frame, hope that's okay
