Vue F.A.Q (Last Updated: 2024 Dec 13 6:58 am)
Actually the very BEST trick I have ever seen for creating FAST caustics is to actually blend them into the texture map- I wish I had the image to show you- of three dolphins- because it really worked great... However, for caustics otherwise- go load the Undersea scenes from the Vue 5, V5I CD's by Michael Jannsen called, amazingly-- "Caustics"... Caustics can be applied through your lights as a Light Gel. You should find at least TWO of them (Caustics)in your Vue Mat Library installation...

using a spot light with a caustics light gel is the best and easiest way to cast caustics on your scenes. But the Vue ready made caustics light gels are not very nice. I suggest you use this freeware called "Caustics generator" to make your caustics yourself, and apply it to your light.Good tip on the Caustics software. Your main problem in the scene, I think, is that because you are using a photo background, the caustics spot gel won't work on it... -so you might want to use the caustics software that Bruno suggested to ALSO make a subtle caustic effect on the background image- but ONLY in the FOREGROUND area- using Photoshop (or whatever you use). That way it will match with the 3D part...
Thanks All for your help, I have downloaded the caustic maker which is excellent and I have saved the Michael Jannsen light as an object and used it in my Dive babe image with some success but I think I will have to work more on this to get those crisp white caustics like you see in swimming pools and shallow tropical waters without volumetric light beams Regards Keith
