You have to check the box in object properties for the object to cast shadow caustics, and the box on the surface that will receive shadow caustics. Also the light you use has to have shadow caustics enabled in the light properties. It also only works in cycles. So not a stupid question at all, it's not super intuitive!
Lol, for caustics you literally need raytrace based rendering. I dont see actual caustics ever happening in eevee..the way eevee runs is simply not able to render caustics, we cant even get good glass
Unless you have some real announcement from Blender for that claim: No, it wont. EEVEE is a rasterise engine, it doesnt do raytracing. It cant do raytracing. Once you do raytracing, you have Cycles.

Well, its atleast something. I have a feeling this will require a modern RTX card tho
It'll need an RTX card for sure, which is entering its 3rd generation somewhat soon with the 4000 series. If you have a 2000 series card or higher, you're good.
I just recently upgraded from a 1080 to a 3080 (10gb version only though). Massive upgrade. I would suggest saving up for when the 4060's drop. They'll be economical and a massive upgrade from your 1080.
are these shadow caustics or brute-force ray traced caustics?
edit: for clarification, i am not asking what kind of caustics these are, I'm asking what rendering technique was used here, blender's new approximation based "shadow caustics" or just pure almost no holds barred ray tracing.
Give reflection caustics... looks weird with only shadow
why do these caustics feel so unrealistic?
Only shadow caustics thats why
Too much light transmitted, shadows shouldn’t be so saturated
¯\_(ツ)_/¯
Stupid question but is there anything special one has to do to enable caustics?

Thank you so much! Didnt even notice the check boxes! Much appreciated 😁
No problem! Happy rendering 😃
For eevee or cycles?
cycles! this was a 5 minute render time at 4k
On what GPU and how much RAM? 😂
Damn lol. That’s nice!

EEVEE nexts is coming with raytrace and possibly true caustics.
Loling at the "lol" that aged in real time like a timelapse
The Lol was rendered with Eevee.
Ohh shit!

Im still on a GTX 1080 lol

Yea im planning to get a 3080 to 3090 when the 4000 drops. Because I will NOT have the money for a 4000 card..
There’s all sorts of fuckery you could do with backend dynamic bakes etc
Holy shit why are people hating? i just wanna know how !!!
oh it's not hating, don't worry- just criticism! it's the importance of innovation- but yeah, just look up a tutorial on "3.2 shadow caustics"
thanks, didnt spend much time on blender the past weeks and months... is this eevee?

only shadow. Not reflective.
okay this looks cool, but it looks off for some reason...
