Blender Shadow Caustics | Beta Build 3.2.0

[@richard29sher]

I appreciate having this feature explained and demoed. It takes time and a clear mind to do these, so you should know that your efforts are so very helpful.

[@djtutorialscgi]

Of course!

[@jcsekinger]

thanks ! (and thanks to Cycles and Blender dev)

[@djtutorialscgi]

You’re welcome!

[@maxmaxed2887]

Blender Dev just told me that there are limitations to that technique i.e. no caustics from liquid inside of glass and I have to deal with it lol. Screw them. I wish I could go with LuxCore all the way, if only LuxCore had Material Converter.

[@xaviervicens5217]

Excellent, thank you so much.

[@djtutorialscgi]

Of course!

[@Slickstaff_Stainpants]

i honestly thought they would go the LUXCORE route and have the CPU do caustics and the GPU do everything else. I would make sense.

[@djtutorialscgi]

I agree!!!

[@anaszx90agn84]

amazing thank you very much

[@djtutorialscgi]

Of course!

[@hamidmohamadzade1920]

thanks i think this is very grate

[@phralma1000BC]

They improved in the caustics game significantly but yet to develop to the level of luxcore. Also u can notice that there are no reflection caustics, only refraction.

[@djtutorialscgi]

This is true- it’s only shadow caustics.

[@vishakvs6657]

Does luxcore support reflection caustics.

[@phralma1000BC]

@@vishakvs6657 yes easily

[@djtutorialscgi]

@@vishakvs6657 yes. LuxCore has more true caustics and reflected light since it does multi light path calculation.

[@maxmaxed2887]

@@vishakvs6657 Luxcore blows Cycles out of the water. The only drawback of Luxcore is absence of Material Converter so you have to manually rebuild nodes for each single material and object including node groups brought from Cycles. The only dev who could build a converter refused to do that and quit. That makes it huge pain in the ass to use. If you build something from scratch though - it's a blast.

Hi, it seems that in the final 3.2 the pointed issues are fixed...

[@Ragmon1]

Doesn't work with HDRIs either.

[@djtutorialscgi]

This is true

[@MarCuseus]

What about adding "Receive Shadow Caustics" to the actual glass itself as well??

[@djtutorialscgi]

Didn’t work when I tried before

[@MarCuseus]

@@djtutorialscgi Alrighty :)

[@nisimjoseph]

this feature was removed from Blender 3.2 Beta

[@nisimjoseph]

Just saw the release notes, it is not supported in Metal (Mac) disabling the Metal will reveal this feature.

[@djtutorialscgi]

Oh that’s some good news :)

[@Leukick]

Doesn't Cycles X render projects faster than Luxcore?

[@djtutorialscgi]

Fast doesn’t always mean better.

[@Leukick]

@@djtutorialscgi Yeah it doesn't mean better image quality. As an animator who needs hundreds or thousands of frames to deliver clients videos, I guess Luxcore ain't it.

[@djtutorialscgi]

@@Leukick different strokes as they say. For animation, speed is definitely something that’s needed but I know quite a few architectural designers and product renderers who prefer LuxCore.

[@Leukick]

@@djtutorialscgi I believe that. I was just wondering if Cycles X rendered faster, thanks for your confirmation

[@djtutorialscgi]

@@Leukick My apologies- the answer is that yes, Cycles X is faster.

[@bqconnect7]

Its only in cycles?

[@djtutorialscgi]

Shadow caustics are in other render engines. This video is only about Cycles.

[@bqconnect7]

@@djtutorialscgi how about in eevee please?

[@0liver_549]

@@bqconnect7 Eevee isn't path tracing engine, therefore it can't calculate caustics like cycles and other path-tracing engines
