Hide objects from renderer

[guest86847]

Hi,

Here I've used a cube with flat material and transparency masking. A point light was placed inside the cube to cast some cool shadows on the ground. I only want the shadows but not the object casting them.

So, an option for "hiding" the actual geometry from the renderer would be nice.

Use an Emissive material and disable "Visible to Camera" and "Visible in Reflections".

Cheers,
Eric

Eric, can you please provide the scene file?

just change your flat material to emissive and toggle off the option Eric (besign) described. That's all.

hope that helps

Nope.

Nope.

Then I hope that this file will explain Eric's solution to you.
You can play with the material settings (like the marble texture) in the opacity channel of the light body parts

Now it's clear to me. Thank you guys.
Problem was that I forget to re-enable the point light. I though you used the emissive to mask the light and illuminate the scene at once.
