I wished this worked for me. Watched it 4 times, connected all the nodes, 2 issues, so it never works completely. First is, if I have both math nodes set to subtract, I get nothing but black. If the bottom one is add, I can see the texture. Beyond those, everything else works as it should, until you say to plug it into the transparent node. When I do, it goes back to having no texture at all. If I put it in the glass node, color, it shows the pattern, but you can never get the black out, so it never changes the water to be clear with caustics. Not sure where I am going wrong, but I am using the latest blender version....but really enjoyed your video and approach to this tutorial. Thanks.
This is amazing! Super clear, easy to follow, and so much inspirations!
This is great! Thanks for sharing! You really explain how everything affects one another and I've learned to use a lot of keyboard shortcuts in my workflow, but I didn't even realize there were keyboard shortcuts for nodes. Looks like I've gotta brush up on my node workflow too!
Thank you very much. Your tutorial is easy to understand. Love it💗
Thank you so much! Very efficient shader, congrats!
Great step-by-step guide of the process.
This looks great, thanks!
Friend whenever you feel sad remember that you make others day feel better, those tutorial are really great, fast , solid and very good,
Really useful and very well explained. Thank you!
Awesome technique, awesome tutorial
Great tutorial, but I had the same problem like some of you guys! There was nothing showing on my render results. It seems that the problem is the Light Path in shadow Ray.
You can either remove the Light path in shadow ray,
Replace it with Fresnel (ior 1.333) OR
Leave the Light path in shadow ray and add one more MIX SHADER right after the one where glass,light path and transparency are plugged in. Unplugg the transparent Shader from the old Mix Shader and plugg it into the new one. ( Basically....dont have the ligh path and the transparent shader plugged into the same MIx shader)
I hope it helps....
Simple and too the point. Thank you!
You’re the best person of this earth Thank you sooo mush for this great tutorial 🙏🙏🙏❤️
Thanks for this fantastic video Dude! Thanks for your efforts explaining how to do this! 🙌🙌🙌
thank you. you are a star - just what I was after
Thanks, this helped me to start of but if you want rounder shapes and animation, I suggest WARPING / DISPLACING the textures. In blender, there isn't a node for this effect like in substance, but what you can do is plug the "color" of a noise texture into the location of the mapping node before the voronoi one. For the animation you can the add (with vector math) a combined xyz and animate one axis the axis.
Hope this helps.
Thank you, I had no clue how to do it
explain more simply please. "add a combined xyz..." what does this mean exactly

I have been waiting for this !!
Awesome ! Thank you for your help.
Sensacional seu tutorial, mano!!
you are a good and tutorial is easy to understand 🖤
Wowwwwwwwww...my god.....finally found this tutorial thank youuuu

Such an impressive technique! *Thank you so much Augusto* for kindly sharing your knowledge with others and helping to elevate the potential of other creatives. Have a great day!
Thanks for the great content.
Impressive work 😨 !
you ar genius. blessings to you!
Thanks bro. This really helped👍👍
you saved my life, thank you
Man you are live saver
Thanks for this tip.
Cool shader!
Great Tutorial, but 2 questions.
1: Where do you plug your last shader in?
2: How is your water blue, mine is just... Not there? That means I can't see anything that we did, it's just, transparent white?
Ans.
1.Surface of Material Output Node
2. The base of the pool is blue.
This question is 2 years old and therefore you must be good at blender by now
Is there a part one to this video? That'd be super helpful
Great tutorial sir 👍
Beautiful, I'll try this asap 😉
Show me your result :)
I'd love to see it.
@@blenderforarchviz3428 where to post? and how to tag you? so you can see our results?
This is so good
Instant SUB
Thank youuu < 3
OMG. ✨✨✨ t h e r e s u l t ✨✨✨ you just saved my life and LOOK AT THAT WATER looks so real! thank you!
Nice way working with voronoi. The think I was missing for mine caustics shader
Nice bro! Could you post your result in our facebook community? I would love to see it.
The link is in the description.
good tutorial.
Muito massa o canal, o vídeo em sí, e o inglês tbm! jump of the cat! :) Parabéns!
Not a bad node group for fake caustics but i would note that shorter wavelengths of light are more influenced by IOR (at least if i remember right) so your blue should get IOR added and your red should have it subtracted
Yes, you remember correctly, blue gets more IOR, and red less.
Everyone, the bottom of the pool shouldn't touch the water's bottom, move the pool down a few mm and the problem will be solved.
When that is done. great result! thank you!
The water doesn't have a "bottom"? It is a single thin plane. I think you mean the two geometry's shouldn't be touching? Either way, didn't work.
@@dynamic5109 The water shoud be some sort of a prism (deformed cube) and don't make the inside of the pool tiles touch the water. Hope it helps!
@@hierandos4741 Thank you very much for your kind advice, I do appreciate it. I started the tutorial again from scratch and missed the early comments about good topology and to have a decent amount of quads and even a displacement. Very important, since I have added some subdivisions, everything seems to be working now. Thanks again!
@@dynamic5109 I'm glad to hear that! :)
good afternoon. very beautiful and believable . is it possible to animate caustics? teach me how to make animation . thanks.
Very nice tutorial, but, I can´t see the voronoy effect in the water after apply the nodes. GPU model can affect? I have a Nvidia GeForce 750 (I know, is older GPU but...) with 2GB of memory. I follow the instruccions step by step and nothing. Maybe for ilumination setting? I using an area light under the swimming pool in portal mode and HDRI for global illumination.
Thanks for helping me.
In spanish: Vamos, que no veo la simulación de las cáusticas en el agua ni por accidente. ¿Tiene algo que ver la gráfica? Porque no lo entiendo, sigo las instrucciones paso a paso y nada. ¿Es por algún efecto de iluminación también? Estoy usando u HDRI junto con una luz de área en modo portal en el fondo de la piscina.
Gracias por la ayuda.
How do I change the environment that the glass shader reflects?
Are the ripples animated though? how would this work? Ocean modifier? Thanks! very cool
Dynamic paint ;D
Its good result.. I just dont like those node system, prefer parameter.. more easy and faster.
Donyou know if the caustics option added in blender 3.2 actually works with water with volumetric scatter?. I used it on a single surface and get very dark water, no caustics any. Ore. Perhaps I should try an actually closed volume. Issue is the waves choppy surface i created. Not sure how to keep that only on the surface, perhaps a vertex group
You are really clear and this must be a great tutorial.
BUT, I did everything loyally, yet all the things starting from the voronoi textures that I plug to the transparent shader does absolutely nothing...
Same result. I'm wondering if they have since patched this in 2.92?
Since it's a shadow based texture, try to reduce the light in your scene or even complete remove the lights in your scene adding just the HDRI, than gradually add the lights in your scene until have the expected result.
the is shadow ray isn't affecting my caustics like it does in the video. Any held?
maybe you didn't unwrap the mesh
Can you make a tutorial, or maybe someone else can please explain, how you create the plane with the water details and what you used as a displacement map? Thanks a lot! Kinda new to this so this would help a lot. I've tried it by sculpting the plane, but this didn't properly work for me.
there is a video on my other channel showing that:
th-cam.com/video/k6IDjdwpFgI/w-d-xo.html
It's Brasilian Portuguese, but I think will be easy for you to follow along the lesson.
@@blenderforarchviz3428 Thanks a lot, will check it out and see if I can follow along :)
hello sir, where is the file ?
I have a problem. I tried to do this and it worked well. But when I tried to render it, it did not show the same result. The water just looked like any transparent object.
Edit: Nvm I found the problem. I used a plane instead of a cube.
Nice attempt. But I’m afraid the caustics don’t respect the geometry of the pool. Actual caustics are stretched at the walls of the pool dependent on the direction of the incoming light.
Cycles don't produce caustics, this is a method that allow you to have close and fast results. If you want real caustics, render witouth them, copy the scene for luxcore, render objects with bleck except the pool and render light paths at 100 %
Then mix both in the compositor
@@hugoantunesartwithblender wow nice tips dude, thanks
@@hugoantunesartwithblender cycles can render caustics fine it just needs a few samples like 4k to 20million
@@Bestman8 that's not a few xD the way I do now is mixing the pass between cycles and luxcore
can you give us source file?
...No
