i have a scene where i use Arch & Design materials, a free directional light as a sun, and as environment map mr Physical Sun.

with all that i want to render only the shadows from the scene.

i tried to add ass a shadow map as a render element but it's renders black.

i also set up the Shadow Map on the light to Absolute Map Bias --> still doesn't work

the third thing i did was to chose mental ray Shadow Map but it looks that the scene is rendered entirely with the objects.

please help.

Maybe the black you rendered out has a channel? Just a thought.
