Hi.

I think I've run across a post asking the same thing, but can't seem to find it now. Anyway, I have a ground plane with a diffuse material and it is set to "Matte". In PMC, I have Alpha Channel enabled and Environment disabled. A couple of questions:

1. The manual says you need a light source. Makes sense...No light source, no shadows. But can the light source be the HDRI environment? I am not having any luck catching any shadows from the environment image.

2. With Alpha Channel selected, I would assume an alpha channel gets saved out with the render. But the only file formats are png and exr, which do not save out a separate alpha channel. What am I missing?

Thanks!

LOOOOLLLLLL! Would help if the damn ground plane was...UNDER THE SUBJECT??? Ain't gonna be catchin any shadows if the mitt ain't under the ball.

Glad you got it!

You have to love the dumb ones though: in my case I had the normals reversed so no light was coming out and no shadows were being cast.

Doh.

Heheh. The human brain is a dangerous thing. )
