Shadow under character

Hi, if I want to render out the shadow under a character seperately, what's the best approach? I have a quad the character is standing on, so I guess I'd make the charcater shadow casting and turn off renderable, but how do I get the shadow to render and not the quad?

I'd like to render a tga image sequence and add the shadow in AFX.

You can set your character to be renderable but not 'visible to camera' in the object properties. this will cast a shadow / gi / reflections etc... but not render the objects primary visibility. Great for splitting up passes

Ok, thanks. If I'm rendering out as image sequences, does this give me the shadow as a seperate set of images? I'd like to just bring the shadow shape in as a layer.

Just use 'Render Elements' in the Render dialog.

If I was to render the scene 'in-camera' so I have the background on a 2d plane and the character is 'floating' in front, I'd still need shadow to plant his feet. How hard is it to have a transparent plane and a shadow effect?

Depending on which rendering application you're using it can be as simple as applying a matte/shadow material to the ground plane.

Ok thanks, I'll give that a go.

I'm having some problems getting this shadow effect to work. I seem to be missing some options in the material browser, and the basic matte/shadow material doesn't seem to work. I've seen tutorials where they select matte/shadow-reflectionwith mental ray and the background image is dropped in, but 'browse from' new option is missing so I can't do that.

Does that look right?

Is mental ray currently set as your active render engine in the scene?

Yes renderer set to mental ray in the render setup.
I am getting a mental ray error, 'not supported by translator, will render black' I just need to apply a matte shadow material to a quad so I get a shadow under the characters feet, but no luck so far.

I'm not sure that error applies to the matte shadow material, but I still can't understand why I'm missing the map/browser option. Looks like a bug.
