Emission through glass.

Support Lighting and Rendering

Hi folks.

I’m a bit confused with emission and glass, not lamps.

I have an object set to emit, between that and the camera is a glass object. All properties are correct with the glass object. A lamp’s light will shine through correctly, but emissions don’t. The only way I’ve got around this is by adding a lamp near the emitting object, but this isn’t correct surely?

What am I missing?

Thanks.

Don’t see much of a difference…
Left (red) = point lamp / right (green) = mesh emitter / default glass shader:

Could you post an example scene with your issue?
Is Multiple Importance Sampling enabled on the mesh emitter?

My stupidity, I went though everything from scratch, somehow I’d managed to enter a clamp setting. Thanks Ikari.
