You caught that.. hehe!   Thanks for the info, I will give that a try.  I have all the liquids set to water right now.  Maybe that's the problem......   If I set them to glass I will lose the caustic reflections won't I?

I think the 'water' material is a Lux 'Glass' anyway, so maybe caustics will still happen? worth a try! I might give that a go too... `¬) ...Your caustics rock at the moment!

Thanks!   I might just leave the flask on the right that's producing all the caustics as is and set the others to glass.  Worth a try.....
