Questions about glass?

[sburkhead]

I am wondering why my glass is not glowing more? I needed to model this light. It has a 5mm thick glass. The light on the inside is an area light. I have pumped it up a lot, but still get areas of the glass that do not light up. Thoughts?

got it figured out.

You enabled global illumination?

yeah, please post your solution, may help others that are looking for help with this as well.

Adding a tiny amount of roughness will help too... since perfectly clear glass does not glow.

It will be interesting to know how you figured out...

For glass it helps to increase the number of ray bounces in the lighting tab. Global illumination should not be too important. If the model contains diffuse elements then it may help to enable caustics. As Will stated, adding a some roughness to the glass helps as well.
