... only shadow to render

[megaflaizer]

you ahve to apply the matte material to the object casting the shadow

but it will still occlude the shadow

[Jed]

You can do as megaflaizer said, or you can uncheck visible to camera in your object properties. This way you will have the shadow but no object and no occlusion.

!! d00d where were you two years ago when i had this madd compositing pipeline to do this instead

please just say it wasnt a max feature back then [v 2.0]

[Jed]

Indeed I think it is a max 4 feature;) so you definitely had to go with the matte shadow stuff with v. 2. I guess people starting with max 4 will never know their luck.

how can i render out only the shadows without the objects?

maybe u need a B/W image of the shadows?...& no obj even the
ground plane?....then use RENDER ELEMENTS in the renderer dialoge box.
