  • $\begingroup$ Why not use Cycles? It can do caustics just fine. $\endgroup$ – John Dvorak Feb 14 '19 at 14:19
  • $\begingroup$ thank. can you post a good tutorial using cycles in caustics? i can't seem to find one in youtube, tutorials mostly use yafaray. $\endgroup$ – managi Feb 15 '19 at 12:28
  • $\begingroup$ Just set up the scene and materials and hit render. If it's too noisy, increase the number of samples (slower) or enable denoising (reduces accuracy, and may cause glitches in some cases). $\endgroup$ – John Dvorak Feb 15 '19 at 14:25
