Chrome, reflection without objects


Recommended Posts

Say I've got a sphere with interesting geometry around it. I've used the default chrome shader (hopefully that'll work) and that seems to work if I render everything all at once. But how can I get just the sphere with its reflection without the objects being rendered too? Now, I can make them phantom, but then they cast shadows and I don't want the shadows in the scene or in the reflection. I can make them phantom and not link them to the light, but I need them lit.

Something tells me there's an easy solution, I just don't know what it is.

Test file attached to save a couple minutes setting up a scene with an objects, camera, light, and ROP.

Ok, answered my own question here.

1 - Set objects to a constant shader, they're not going to receive any lights.

2 - In the lights Shadow tab add the names of your objects to the Shadow Mask channel

3 - In your object's Render tab turn on Phantom

Viola!
