Rendering Matte shading and background issue ...

[Masoud]

Hello;

Please take a look at image bellow. I would like to set an object's shading to Matte shading so that it shows background image and acts as a hole.

When I turn ON matte, it renders background in black color (instead of background).

I tried several presets in "Render Visibility" slot, without success.

 

Thanks for helping.

Have you tried rendering it as phantom (in your mantra node) ?

That is what the matte feature is supposed to do. Matte renders are designed to be used later, not in the same render.

To do what you want, you could project the background image onto the sphere, use that as color in a matte shader.
