Render Layers - Compositing Problem
 

Hi,

I'm having problems with rendering layers. This is the first time i'm using the option. I want to render the objects in the scene seperately and later want to composite them in maya fusion.

but i'm having problems in compositing. if i put the 'box' on the top layer the output is the second picture. if i put the 'box' in bottom layer the output is the third picture. How can i get output as in the first picture ?

Help me out

The first picture is rendered without 'render layers'

Box on Top Layer

Box IN Bottom Layer

There are 2 ways around this problem.

One easier than the other:

1. You can do an animated alpha by hand in Fusion.

or (easier)

2. You could duplicate your scene, and rename it so you don't overwrite the original.
Then you can apply the "Use Background" shader to everything BUT your box.

That way, you will get object "occlusion", meaning it should comp normally like in your first pic.

Does that help?

thnx race the second one worked ... and easy too. :)

I'm not trying it yet, but how/where is the background shader option.

It's in the Hypershade, with all the other basic shaders like Blinn, Phong, etc.

Just select everything but your chains, and your box, and apply that shader to them by right-clicking over the shader in the Hypershade, and .... well, you know the rest:) hehe..

Good luck!
