Hi there! Our current version natively supports 4.2, however unfortunately EEVEE Next still does not support the necessary shader features required for the caustics to work. They are strictly EEVEE limitations that we can't do anything about. However, our Dispersion and Thin-Film solution still work perfectly in EEVEE Next! :) As for an update, we aren't prioritizing any as of right now, but we do have many plans listed out for some nice quality of life improvements, when we are able to finally get around to them! :)

It currently works on every version, and you do not need to rebuy this addon for any version of blender. :)

​@@SMOUSEYou've created a Banger thanks you 👍, have a good day 🤩

ok, the principled shader plus work but how do you use the others like, glass plus shader and the caustics module?

alright, I've learned that for some reason, I can't use them on "flat" beveled cubes. I added a ball and cylinder, both show the caustics just fine.

Hi! The caustics are not supported in EEVEE natively due to EEVEE's limitations, but they "can" work a bit under very very specific conditions. For that reason, the caustics are only really advertised as being supported only with Cycles. That being said, the Thin-Film and Dispersion do work natively in EEVEE. However all of my promotional material was done with cycles to squeeze every last bit of quality out of the renders. That may change with the coming improvements to EEVEE Next. To reassure you though, I've recorded a quick demo in EEVEE for you, quickly showing off the Thin Film and Dispersion effects. You can see it here! :) streamable.com/7u825f

Thank you, Micah! :)

Hi there! For Eevee, you'll want to make sure Ray Traced Refraction is annealed in the shaders settings, and that Reflection is enabled in the Eevee settings for glass to work properly. This makes Dispersion look better, however Caustics are only limited to cycles at the moment. Thin Film and Dispersion should work natively with Eevee

@@SMOUSE Thanks for your reply. I'll try again as you suggested.

Hahah thank you so much! That is actually exactly what it was inspired off of! 🥰

Hi nebula! There should be several scene files included in your download library that show how the underwater caustics were done. Those scene are easier to explain it than words, as you can see and tweak them in real time to see how they work. :)

It does indeed! :)

@@SMOUSE Excellent!

It is pretty awesome!

Sun lamps don't support texture projection, so just Spot Lights and Area Lights (with a spread of 0) are your best bet :)

Make sure that the setting "Plane / Light Gobo" is set to Plane in EEVEE mode, and that you're using a plane. I totally forgot to cover that step in this video, but that setting is necessary for the gobos to work with EEVEE. Let me know if that works!

@@SMOUSE Didn't fix it for me!

@@mattdodds3908 What preset are you trying? Every one should be compatible with EEVEE

@@SMOUSE Every video one

@@mattdodds3908 Go ahead and message me on discord so we can troubleshoot this better 🙏🙏

Thank you xDaShaanx! I am so happy to hear it!

It sure does! :D

Thanks@@SMOUSE

🤫😏

@@SMOUSE haha I will be waiting this friday eagerly then 😏

Is it still not working?

So the Shaders Plus v3 are just replacement shaders of the defaults, so it takes the default shaders and adds the Shaders Plus features to them. The modules are individual node groups of the Shaders Plus Features, that can be injected into any existing shader setup, even those that are not Shaders Plus based. So if you're revisiting an old project, with the V3 shaders, you'll have to replace the main shader node and rewire and set everything if you want it to have the features. Whereas the modules can simply be slotted in without breaking anything. The shaders are great for normal workflows, especially starting from scratch, and the modules are great for existing mode setups to have those features non-destructively :)

@@SMOUSE haha, hey I spoke to you on discourse the other day, cheers!

Hahah, I had a feeling it might have been you! No worries! :)

​@@SMOUSE So, to imagine it in my head, the modules are like applying with a single click the effect of this plugin on a mesh stack of a wall building? The modules have the manual sliding panel available that has shader plus v3 or will I have to enter the group and modify the look I want there?

This addon only works on custom node groups now, instead of all nodes, as of Blender 3.4 and above 🥲

@@SMOUSE okey thx

Mostly time, these shaders and making products had unexpectedly become my full time job, and the customer support, development, personal business side, and making additional products has been the main focus, and unfortunately that's been taking time away from being able to make videos. I do plan on making more videos describing the features as soon as I am able to, but to answer your question, I didn't feel like describing all of the shaders in this video was necessary, because they all share the exact same features that comes with the principled, and there's no core changes to the shaders themselves. So making glass with causitcs will look the relatively the same with Principled vs Glass BSDF, minus the extra shader settings that come built in to those respective shaders.

Thank you very much! Let me know if you ever need any help using the shaders! 😺

@@SMOUSE I’ve been enjoying the caustic glass presets a lot and had one slightly odd question in a very different direction. Do you have any advice on using your shaders in conjunction with video textures or with transmission? I have a music video I’m working on that needs some bloom/glare on one shader and video texture on a different one for a fluid simulation, but I was trying to find a way to work in some caustics. So far my approach hasn’t been the best and I end up having to go with one or the other. :)

The caustics are driven by shadows, not by refraction. I forgot to mention but the caustics do simulate that and reacted to the shaders IOR changes, but not physically accurately. I am working on getting some tutorials done though for achieving realistic results with them, like for the examples I have in this video :)

@@SMOUSE I thought so, so it's utilising the shadow raycasting and then creating an effect around that rather than actually calculating caustics that quickly.

@@jpjapers correct, yeah currently it's not possible to simulate physically accurate caustics in Cycles in real time. A branch of Unreal Engine 4 managed to do it a few years ago with some amazing results, but not sure what ever happened to it. I havent seen anything else like it since. LuxCore is up there, but it's got too many workflow limitations currently to stand up to the mainstream renderers
