I remember seeing this post on instagram the other day and was thinking gosh I wish there was a good tutorial on making water look like that, my man max served us right away. Ty :)

[@josephhennessy2978]

facts!!!

[@GortTeam]

bruh same

[@DigiCube4]

Bro........these tutorials. You really got me in blender learnin. Thank you!

[@spydergs07]

This is a great work around to not only make it look very realistic, but cuts down on render time big time, and you don't get noise from normal caustics. Very well done.

[@HarryPotterFan1307]

Bro, your skills are nasty. Keep the content coming man. Tier one for sure.

[@iamCoIony]

i just started learning blender a few months ago and this is exactly what i needed and everything more wtf. thank you!

[@pandoraslove840]

THIS IS GENIUS!!!!!! I went through so many video on how to make water causics, Geometry nodes, procedials and other thing that didn't work. BUT THIS was quick, simple, easy to understand AND IT WORKS EFFECTIVLY OMG THX SO MUCH!!!!!

[@itsjuliao]

I was literally searching and experimenting with water caustics last week! This video is perfect timing

[@craigernstzen2372]

Max, 5 minutes in and I am amazed. I was battling with caustics in Blender. I tried LuxCore which is fantastic with light, but it's not fantastic with my PC lol. This is great, it's a gobo.

[@FeatheryWonders]

Really love your work man! ❤

[@maxhayart]

Thank you

[@pc-ninja]

Great tutorial one of the best on water effects

[@Raiin0311]

holy this is SO much esiaer then what Ive done before haha. Thanks Max!

[@Tachastasiia]

I am completely blown away by the fact that you can see your cycles render view so easily... I have no idea how my animation of caustics looks like.. it's all blurred and denoised..

Always learn new things from your videos, thanks so much, bro !

[@FilmSpook]

Pure Genius, Thanks Max!! Your work is Top Notch. 😎

[@simonzhang3D]

Instead of inserting keyframes you can just type in the property : #frame. This way you have it animated the moment you press play. If you want to make it slower just divide it like #frame/500. This saves some time :)

If you search up ray types in blender docs you can see a diagram of a traced example. So the Camera Ray is the first ray from the camera before it turns into something else (when hitting a surface). So by masking if it is a Camera Ray or not, you can mask for only the surface in effect. From testing I believe it is the Shadow Ray which is screwing you over. I am certain that filtering by Camera Ray is the not the most accurate since it does lose out on the surface to send diffuse reflections and the other types (ex. the consequence is that if you see the water in the reflection of another object, the water is invisible). So if you want to have that you can filter by Shadow Ray (you have to invert it since you _dont_ want shadow casting, which can be done via color ramp). You dont have to do this in shader either, you can do this to the whole object by going to object properties > visibility > uncheck shadow (though using these properties is not always desirable if the object has more than one material or like you want more control). You could turn off Diffuse as well if you dont want bounce lighting. Of course you dont have to turn it off any of these rays completely by multiplying (or use like a color ramp) if you want that control. The benefit of turning off all the rays besides directly Camera is that it is cheap (as it there is less compute), just choose your best fit poison! The power of tweaking Light Paths! Lovely tutorial of controlled caustics, great examples and looks great

I like that video you say on how you started blender No school No direction 😂😂😂

[@richardconway6425]

This is really clever Max! Very resourceful, a bit like using animated gobos with your light source, but a different approach. I thought the end result looked really good, and the colour pallette was very appealing too. Lots of lovely green shades on my juiced up amoled Samsung tablet. I didn't realise that you could project an image with an area light, that's not entirely intuitive, but very useful to know. One thing I would find very interesting, is if you rendered the same scene in cycles, but with caustics enabled instead. So 'real' caustics instead of the faked ones. I would be very curious to see what it looks like, and also what it does to the render time. Your machine must be very fast, because the viewport performance for rendering (it was rendering in cycles, right?) was so quick. You must have at least one 4090, if not two. Did you colour grade the final output in 3rd party software? Colours looked so good.

[@cyrilbergeon9906]

thanks. I was trying a procedural method with voronoî texture. Works well but not realistic enough. So, thanks again for this one.

[@patnor7354]

Great stuff

[@landel_]

I took some time from Blender and I was kinda 'meh' to come back. What a nice tutorial to push me back! Amazing work! And thanks for the valuable tips! Also: How much post-production do you use in movie editing softwares?

[@sanskii2347]

Nice tutorial, I wonder if making the spread of the caustic area light to be a very low value (like 1° instead of exactly 0°)would probably solve the problem of caustics not appearing on those 90° faces, so we wouldn't need extra area lights. Also how did you make the caustics appear on surfaces out of the water, like in those pillars in the initial rendered scene of the video? Did you make the caustics area light bidirectional somehow or was it something else?

[@richardconway6425]

He added additional spotlights around the scene, like ones pointing directly at the pillars, and used the same node setup he used for the area light, with the fake caustic effect.

[@AUSCIPHER]

Nice!

[@Rawrlz]

Awesome thank you! Odd request but can you make any tutorials n64 style graphic effects?

[@montydog990]

i would say the caustics look a bit unnatural as they dont really tend to scroll like that and is more of a dancing in place motion. but looks amazing none the less, especially on freeze frame

[@Brucelam1511]

can you do a tutorial on how you use geo nodes for lily pads?

[@yofpassion]

awsome job!! but... can i also use this way in blender 4.2??

[@senatoraz]

genius

[@MoonoTheActivist]

Hey would you please make a video on your shader viewport on how you have it while working

[@Corza]

Smart!

[@aurafireheart]

How the fluff do you have an option to add a node setup to a light source. Mine doesn't have that option. I even downloaded the latest version (4.1 at time of writing this) from the official Blender site and it doesn't have that option either.

[@maxhayart]

In the shader editor you have to press the Use Nodes checkbox with the light selected

[@aurafireheart]

@@maxhayart That's what I'm saying. The 'Use Nodes' checkbox doesn't show up at all, whether the light is selected or not.

[@richardconway6425]

@@aurafireheart is your rendering mode set to cycles? I don't think this option would be available in eevee.

[@aurafireheart]

@@richardconway6425 oh its in cycles. Now see that makes a little more sense and would have been really helpful to know what mode it was meant to be in at the start of the video. Thanks for the help, friend.

[@richardconway6425]

@@aurafireheart yeah, we've all been caught out by this kind of thing in blender. I remember getting really frustrated in the compositor, because I couldn't see the options I wanted for denoise. Problem? I hadn't enabled cycles as the render option. 😭

How did you manage to get such crisp render in viewport without mad flickering between the frames with Cycles?

light materials don't work in Evee, is there a way to get something similar with Evee? I'm not a fan of Cycles since my GPU is just a 1650.

[@TECHDAWN]

[@mastermill79]

Would there be a caustic effect to that extent on the very shallow parts as well?

[@jahluu6825]

when I put the spread to zero, it goes invisible entirely. luckily, the water in my scene isn't exactly super visible so i can forgo it for now but i would like to know if there's a workaround

[@jahluu6825]

i figured out the solution BTW. if anyone was planning to say "recalculate normals" you would have been right. The shape of my body of water was pretty complex, had it going down a canal. so I guess all those extrusions sorta messed with it.

[@eitantal726]

you would think you'd get caustics anyway, given they're natural phenomena. Why do we need to introduce them via a gobo? do they only occur subtly? or only occur at certain water depth?

[@maxhayart]

I guess I should have explained this in the video - it’s extremely hard to render real caustics in 3D. Yes you can get them but rendering them in animations especially is something that doesn’t ever make sense to do because of how long it would take. I think Corridor Crew made a video on this if you want to know more about why it’s super hard to render them for real.

[@eitantal726]

@@maxhayart Never trust a video with more than a million views. Caustics are not hard to simulate. See video: Kaizen NEW shadow caustics in Blender 3.2

[@thecodinguru]

Can't we use #frame for the w values?

[@IsraelSocial]

I'm new on this of making scenarios on Ue 5, can you import it to ue 5?

[@richardconway6425]

Not directly, no. I mean, you can't just take the whole animated scene and just drop it into unreal. You can import all the models, the hard surface environment stuff, but unreal uses its own shaders, so you have to set up all your materials in UE with unreal's shaders. That's my understanding. Look into 'bridge' addons that help you do the blender>unreal thing, like blender2unreal. I don't use unreal, but I am interested in it. Perhaps something like USD export may help with this in the future, but I don't think that is possible yet.

@@maxhayart i have the same problem, yes its an area light and when you set the beam to 0 it only shows the primary colour of the picture without the beam spreading. Couldnt figure it out yet

okay, so the picture kind of appears divided in 4 pcitures when you put a texture coordinate with mapping in front and set the texture coordinate to object and you scale it down with mapping. But I dont know what that means or how to fix it.
