Rendering in Layers

[gmask]

>>>Now, in order to render the individual passes I must do a batch render? Rendering using the normal way only renders one pass.

Yes you must batch render.


>>if the layers are rendered separately, then what happens to the shadows if one object lies on top of another with a spot light overhead?

Since layers are exlusive you will have to put copies of objects in the other layers that have the primary visibility turned off. Or turn of render layers and just render on eglobal shadow pass.

>>How about this default render layer; what is it for?

It is just a catchall for any object not assigned to a render layer.

I see the reflections are there so why not the shadows as well?

I don't know why it doesn't work for raytraced shadows but it does for depthMap shadows. So either use Dmap shadows or place shadow casting invisible objects in the other layers or do the one global shadow pass.

Let's just say I have two torus locked like a link chain. Each torus is in a render layer. How would I combine the two rendered images so they look like they were rendered as one?

You'd have to copy on of the objects and give it a blackhole shader. A blackhole shader is a surface shader with a full black out matte opacity.
