Thanks a lot for this video!

[@Dina_tankar_mina_ord]

very good video. thanks.

[@krissosful]

Nice simulation, keep going👋👋

[@SourceAwareness]

Many Thanks!! 😊

[@jostv.2726]

I always thought that Cycles would really struggle with caustics and that only the latest versions of Blender would have solved this problem with an option that only workes on CPUs. But that makes it look so much easier to render^^ Thank you for your video") I have never seen this option in Blender and I am definitely going to try this out ")

[@B1G_D0G]

Could you teach us to do an animated version with a water simulation?

[@ahammedfarhan]

Nice video man. Maybe you can lower the saturation of the colour of water surface.

Nice walk through the set up. Something is missing though. Perhaps Blender doesn't care in its caustic calculations and the effect will be the same but water is not an infinitely thin layer ( like an X-Y plane with some subdivisions but no z-axis thickness). The refractive index of the entire volume/column of water from where it hits the water surface all the way to the surface upon which the caustic patterns are cast is ALL water and, like a lens, the light is more affected the more of the material volume (the water) that the light passes through. So perhaps the caustics solver just assumes that IOR all the way from the water surface all the way to the caustics receiver but I submit that the look of an underwater item should also have the volume that surrounds it be calculated ,i.e. some light diffusion (unless the water is EXTREMELY unnaturally crystal clear) and some light rays in the water ought to be visible too.

Hi! Nice Tut. Do u Have any idea why I don't have the shadow caustics box in my light sets Blender 3.4 silicon Thnx

[@bry_3darchive]

Shadow Caustics Simulations is currently only available in Cycles. Perhaps you are currently using eevee for your Render Engine that's why the Shadow Caustic option is not showing in your light object properties

[@benveasey7474]

Can you show us how the water looks from above when animated and with caustics? Thanks

@@bry_3darchive Thank you!

[@zlaio7082]

Can you tell me wich Voice Programm you used for the AI Voice that would be awsome ( I subbed :D )

[@bry_3darchive]

It's not an AI voice though 😅 But thanks a lot I guess?

[@zlaio7082]

Oh wow sorry 🤣😅 Some moments just sounded like Ai voice idk

[@simonw.1223]

7:52 somehow the light doesnt reach the monkey.

[@sebbosebbo9794]

no caustics in the shadows of Susanne back head....I thought thats shadow caustics are for that ...looks strange....

[@bry_3darchive]

well of course caustics wouldn't reach the shadow of the head since it's blocking the light, as it does in real life as well :)
