hi everyone. i'm lighting a scene with some area lights on the walls corresponding to the position of some wall-hanging lights. i've connected one mental ray light to the light shader of these 4 area lights, providing both illumination and shadows for my scene. my question is: how do i create a shadow pass for the shadows coming from this mental ray light? cause i have 4 distinct shadows overlapping and i need to composite them and trying to merge them together to have a continued shadow rather than 4 visible distinct overlapping shadows. thanks.

I don't know if you've come up with a solution to this yet. Here is a solution that works ok: http://www.rethinkfx.com/tutorials/compsoft.htm - under "Shadow Pass". Yes, it is for Softimage but the Mental Ray workflow is the same...

Unless you're using MR lights (such as physical etc)... sorry. Anyone else?
