Cast shadow option in material

[flashstickman]

Hello!

I have a yard scene where everything is attached as one object (I need to render a lightmap for whole scene). And I need sand piles (highlighted in green) to not cast shadows.

Is it possible to make it via material setup? Assign 2nd mat ID to sand piles and turn off shadow casting? What render/material allows that?

Apparently it is possible even with Scanline renderer. Unchecking '2-sided' checkbox have done the job.
