How to setup caustics in V-Ray - Pool Tutorial | Cg Blog

V-Ray Caustics in the Pool

Share with your friends!

Today I show you how to setup caustics in V-Ray and getting this result:

In these years I worked a lot with live trainings (see here) and from the 2012 I will work online with you: 1 easy lesson per week we’ll learn a lot of things togheter.

This is our goal:
Give you easy, fast and comfortable knowledges about 3ds max + V-Ray + photoshop, every week.

Last year I wrote a post about Caustics here. It’s time to update those contents with an effective video and a couple of files to let you test and play with parameters. This is CG Blog Premium and for this time it’s free. Another gift for you… happy new year ^^

Watch, try, learn.



  • Important: disable Affect Shadows, to get caustics (this is not in the video!)
  • Enable caustics
  • Set Photon emit radius (V-Ray Sun)
  • Increase Caustics Subvids (Vray Properties > V-Ray Sun)



/ Also Learn Corona Renderer

        Thank you so much!

        I work in Rhino v5 64bits and Vray 2.0 just came out for Rhino 5 and the only files I can open is 3ds..

        Your tutorials are great and they work just the same with Rhino 5 🙂
