I've been getting quite a few questions on problems people are running into. So here's a little troubleshooting list if you're running into issues; 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) available here; www.blender.org/download/ Hope this helps with some of the more common issues! Feel free to expand with your own troubleshooting points so people can see your solution. They may be facing the same issues!

Nice tutorial! 2:28 One thing i would suggest is to enable "harden normals" in the bevel modifier options, and then enable auto smooth. That way you get a bit more accurate shading on the glass.

Finally please make sure you have no conflicting addons like the 'photographer' addon enabled! Hope this helps.

@WingedWolf-pq7ng

Hi, @njdotson is probably speaking about Light Paths > Caustics > Reflective & Refractive. You see, Cycles has always *supported* some level of caustics, they just didn't work very well. In version 3.2, Blender got an extra Caustic feature based on "Manifold Next Event Estimation" (whatever that is). This feature enables a better handling of caustics for the render engine, the only catch is that you have to tell Cycles *what* light can produce these new caustics, what can cast them, and what receive them. This is what @Kaizen explain in 8:41, chapter: Enabling Caustics in Blender 3.2. Keep in mind that this new caustics depend on the previous caustics, so *you still need* to have Light Paths > Caustics > Refractive enabled. Edit: I forgot to mention, the new caustics *do* take a performance hit, so... try to just use when needed?

Hello sir, I have a question if I may; You've said that one must shade the object smooth, not flat, now, what if I have a diamond, which is virtually perfectly sharp? Would this work?

Thank you by the way for your great tutorials, looking forward for your reply. :)

@KaizenTutorials

Thanks! That’s a good question; but yeah it would require smooth shading. You could fix it though by adding a subdivison surface set to simple and then give it a high resolution. This should make it still look good. But even easier. You can hit shade smooth and enable auto normals in the object data properties. Set the angle to an angle that works for the diamond and everything will still look flat, even though it is shaded ‘smooth’! 💪🏻

Hey ! It drive me crazy rn, I meticulously follow your tutorial to get those beautiful ✨caustics✨ but nothing happens, neither with the glass nor the ocean.

Hello there, Im really new in Blender and Im trying to follow the tutorial, I know that its difficult to explain something specially when you have some expertise on the matter, there are some things that u should explain before, like, I was trying to create the Mix shader with the shortcut, but it didnt work, because i didnt have Node Wrengler activated from the Add-ons, and now im having difficulties to see exactly the same result in your viewport I cannot see my model at all, I can see it in material preview mode but in render preview i can only see the background, looking in your viewport I can see that everytime that you tweak something there is something going on, so i figured out that I needed to change the Render Engine to Cycles in the Render Properties.

Thank you for this tutorial, I came here because I had a problem but alas, didn't find the solution in the video. The problem is that if you place liquid inside the glass (wine, water, whatever) and enable caustics for that liquid, it doesn't work. Even if I set multiple bounces for transmition and transparency, the caustics work only on one level, if I have 2 levels (glass and liquid) shadows become opaque again where 2 materials meet. Which makes blender caustics useless for product rendering like wine beer and so on. a real shame. unless i am missing something?

Well... yeah in Alpha it has been for sure. But... not a big fan of doing stuff with Alpha and/or Experimental builds. So I usually wait for a stable version to start telling people about these kinds of things!

Make sure you're using the latest stable build (3.4.1) and more importantly make sure you're using Cycles! Caustics don't work in EEVEE.

Please use "win" and "+" to zoom in on the screen. All viewers don't have 24" monitor. Zooming in will also help if someone is watching from a tablet or mobile. I understand you want viewers to practice with you, but it may not be possible every time. It is a request.

You videos are great, your "smile" @0:01 freaked me out, bruh. Imagine your audience naked (ok, that never helped me either, but I got jokes as a salve for the constructive criticism). Not like I don't smile like that too most of the time...

@@KaizenTutorials ha HA! Look at the stress around your eyes. I can't give the complete breakdown of the microexpressions of your face (part of body language analysis), but given you don't always look that stressed, compare your smiles and facial expressions across videos. Also as you get older you get at least 3 more OS upgrades. I had one at about 26, then 33 and 43. It's possible, like teenagers can't read ppl's faces at all for the most part, and think they know everything (I don't assert you are a teenager), as your brain matures you will see more and more of what's going on... This face I noticed right away, because it's so common with me too. Only you know exactly what was going on when you recorded the video, so I offer this only as a means of self discovery. Damn, never thought I'd write that phrase, "means of self discovery!" [update: Now that I think about it, I could never tell when my ex-wife, a former child actress was lying to me... my memory was better so I knew she lied weeks later when she forgot, because she would say mutually exclusive things, but I never knew which one was false... so even watching microexpressions is no guarantee on making only great life choices...] Thanks for your videos.

That's more like a fake caustics, some sort of masking shadows IMO. Way far to realism. When you take a look at other render engines it is a bit disappointing.

@KaizenTutorials

It is isn’t true caustics no. Just shadow caustics. It’s a big step up, but nonetheless engines such as luxcore have a serious advantage over it with true caustics

этот метод не работает в новом блендере он устарел
