What is the difference between a cone filter and uh the default one. there are 2 settings for this if you are using mental ray for maya 1.5

well I think that they are call filters. you prabably know what I am talking about anyways.

The default filter is a box filter, which would suit in most cases.
The cone filter will give smoother caustics. You may change the filter size as 'larger filters cause softer caustics'

We use box filter the majority of times. Trial and error

Remember to
- use a Physical light shader to ensure physical correctness
- make the object casting caustics not diffuse
- make the object receiving caustics diffuse
- be patient young padawa

Wicked luck (Ali G style)
