Help!

I have an object which stands on a floor.

I need render pass object only. (no floor)

I need render pass reflection-only from this object on the floor. (no object, no floor)

I need render pass shadow and occlusion only from this object on the floor. (no object, no floor)

Why?

Then I am free to change the floor/ background in photoshop.

Please help me!

Thanks!

Hi,

Probably the best workflow for this kind of scene is use the layers feature, and render one layer with the main object and other layer with floor, each one with the needed passes.

The layers are working but still don't know how to get only the shadow (and other pass the reflection) in the floor layer.

So I don't want to see the floor, just 1) the shadow on it (from the object) and 2) same with reflection of the object.

Freddy

To get the shadows and reflection you can try the layers passes. Enable the shadows and reflection layer passes to see if this is the information that you are looking for.

No still don't get it as I want.

Again, product on floor. On floor shadow and reflection from product. I want to change the floor in photoshop, keeping the shadows and reflections!

Hmm, it should work. Check the attached scene. The sphere is in the layer 2. The beauty pass in this layer has the sphere, the layer shadows has the shadows over the floor and the layer reflections has the reflections also over the floor. Is this what you are looking for?

The scene.

Hi Juanjo, thanks, we are getting closer

It works in the preview window, can see it when selecting the shadow or reflection or beauty layer.

But now, how to render this with F9 or scene rendering? How can I save the layers now?

Thanks!

Freddy

To render the layers you need to enable the layers rendering in the render target root node options panel, and to configure the passes file names and options, you need to check the render passes node options panel.
