rendering rpc people
show user profile  julieann992
I have already rendered a large concert hall scence, and I have been told that now people need to be in all the seats. I have placed all the rpc people in the seats (they don't need to cast shadows or anything as it will be semi dark in the audience). Now I need to figure out the best way to render the people and composite them into the image...obviously the chairs need to be somehow turned on but masked out so that I can delete them in photoshop. I am using 3ds max and mental ray. Thanks and sorry if this sounds like a noob question...I have done some searching but only gotten results on rendering in passes (highlights, ambient occlusion etc) not rendering overlapping objects.

render the things that need to overlap in a pass on their own but render them with a black material and use that pass as a mask

I can't do that with the rpc people because you can't give them another material....they will render as boxes and not show their actual shapes...when I render the people with all other objects/layers another color and select color in photoshop and delete it, I end up with edging around the people of that color....I don't know if I am making any sense here...or maybe I am not understanding you correctly.

Thanks for the response!

Select everything you don't want to render, right click, choose 'properties', uncheck 'renderable'. Or, if you still want them to cast shadows, just uncheck 'visible to camera'. Or you could just hide them. Your question is kind of hard to figure out.

Basically, I want the people to render only. I don't want the chairs to show as solid, but I do want cut outs where the chair would be (i.e. the part of the person's back covered by the chair would not show and there would be empty space/background color where the chair would be). If I hide the chairs what I end up with is a bunch of overlapping rpcs.

Sorry for the confusion.

select all of the objects you do not want rendered apply matte/shadow to them. this will make them not render and obscure the people and yet still give you a cutout so you can composite them.

what are you going to use to composite thiem?
