Maxwell Render | Official public forum

I have following ever recurring problem with Maxwell (3.0.1.3) . It renders only the render and the alpha channel. The z-buffer and shadow channel are rendered completely black respectively completely white, despite having all sorts of shadows in the rendering.

Thanks for any hint.

Make sure "Shadow" is checked in a materials global properties. For example in the material applied to a plane, and you want this plane to catch shadows, turn this option in the material applied to it. As for zbuffer, check that your scene scale is correct compared to what you are setting in the zbuffer render settings.

For the z-buffer channel you have to specify a range of distances from camera in meters. Anything nearer will be white and anything farther will be black.

For the shadow channel you have to specify at material global properties which material will behave as shadow catcher:

Edit: You were faster Mihai. By the way, I've found that Shadow channel section in Maxwell docs is empty.

Thanks to all. This solved my problem. The z-buffer ought to have been self-evident, but shadows not as much.
