Blender 3.2 is here! And with that we are getting caustics in Blender. It's truly amazing! We'll create a drinking glass together and I'll show you how use caustics, because they aren't enabled by default and you need a few things setup for it to work properly. So let's get started and let's get into it!
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.

Looks great in the viewport, but when I render it there's no sign of the caustics on the ground plane? Any idea which setting(s) are wrong/necessary?
Hmm that's weird. These are the most common issues I've run into/heard about. Please check if you tried all of them.
0. Use the Cycles render engine!
1. Make sure you have enabled an object as the 'Cast Caustics' object, with a proper glass, or refraction BSDF Shader material
2. Make sure you have enabled an object as the 'Receive Caustics' object.
3. Make sure you have enabled 'Shadow Caustics' on your light source.
4. Shade Smooth any object that you want to CAST caustics. Flat shading DOES NOT WORK!
5. Check if you have any conflicting addons enabled, such as the 'Photographer' add on.
6. Might be obvious, but please use Blender version 3.2 (stable)
very nice. now i have go back on my last 5 or 6 files and see if it makes them better ,,, lol ,
haha yep, that's always the thing with these new updates! Good luck!
This is amazing! Will there be an option to add shadow caustics for HDRI maps and Sky Texture?
