How to create Rain and Splashes Simulation in Blender

[@Ibbys_space]

I'm so glad that these shader + geometry node-based stuff is becoming so much more accessible!! you, celestialmaze, erindale, and CGmatter are all so good at opening this knowledge up for people to make what they love and I respect it so much

[@tawansunflower]

Thank you so much for your kind words! 😊❤️ I agree. Those people are absolute masters when it comes to geometry nodes, but I'm simply just playing with geometry nodes tho 😂 For example, the rain tutorial is a result of just randomly guessing and trying a bunch of methods until one works.

[@Ibbys_space]

@@tawansunflower seeing people experiment and see what they get out of it and learn is really cool, it's like proof that messing around and doing stuff for fun still gets you somewhere haha

[@fadepanther6224]

This was a great tutorial. I felt a little upset, at first, about the node groups, but after having some experience in those weird things, I can understand why Tawan packed them into some groups. At very least he gave those groups with the tutorial file so, if you have the time and understanding, you can pick apart what he did in them. I had to alter a little bit here and there, but after that I have turned this into something I can test against other rain tutorial things. (Which were often a lot harder to follow or their end result only worked in that singular type of setting). Also, Tawan, you got me hard with that ending with the Default cube. That was honestly touching as heck. ^^

[@tawansunflower]

Yeah 😂 Took me some time to think of how to end the video about rain. I'm glad you like it 😊❤️ I try to make geometry nodes easy to learn for everyone, so that they can achieve great results faster 👍 But yes, eventually those nodes inside the node groups will become very important in the long run.

[@casuffacommeci]

Hi, thanks a lot for the tutorial. I have spherical particules falling with the rain. Same shape as the basic node setup. How can I get rid of them?

The solution is very simple. You just need to place a [Set Material] with a transparent material, between the [Set Position] and the [Join Geometry]

They will still appear in the Layout, but when rendering they will be invisible. Hope this helps.

For Raycast+ the rain goes through the floor, so I added "Position" in source position like you replied in comments but now no splash animation

Hmm can you send me the file on twitter? I can take a look at it

[@cydu]

@@tawansunflower I got it to work, thank you. also was wondering how to increase speed of rain fall etc thanks

[@tawansunflower]

@@cydu You can adjust that by changing the Combine XYZ node that makes the rain falls in the negative Z direction in the video. 👍

[@cydu]

@@tawansunflower thank you, also I was wondering in your $10 pack, if the ripples etc were models (If I can remesh the ripples into blocks) thank you again

[@tawansunflower]

@@cydu No. In the advanced version, every ripple is a simple circle generated with geometry nodes. If you want to use a custom shape, you'll have to modify the geometry nodes 👍 I labled very part of the geo node, so it should be very easy to modify. You can always contact me if you have any question. ❤️

[@arrowpace]

hi, I recently downloaded your painterly cloud setup...it's awesome! it's just that whenever I make clouds using your geometery nodes setup...those cloud plains cover up the entire space infront of the camera...lets say I wanna make a scene where a jet is flying over a layer of clouds...so I make the clouds using the cloud shader and geometry nodes...but when I place a jet over it, it just falls behind those cloud plains...unlike your 'painterly brush' setup where the plains are actually on the object rather than stacking up infront of the camera...and again...your cloud shader's really stunning...it's just that every object I place infront of it gets hid cuz of the stacking of all those plains...is there any solution to this...or a workflow I can use to manage this situation..I would love to hear back from you as soon as possible 😃and thanks again for creating such awesome stuff for artists like us 🙂

[@tawansunflower]

In the Geometry node, there should be a Set Position or a Translate Instances node (I'm outside so I cannot remember. Sorry 😭) which is responsible for translating the cloud towards the camera removing the z-fighting artifacts. You can disable that node and it should work. However, it must be noted that you may see some z-fighting artifacts while moving the camera.

[@arrowpace]

@@tawansunflower wow I just disabled the Set Position node and it actually works now even though there's a slight decrease in density & that fluffiness around the edges...but it's still looking good & I can adjust the density using geometry nodes modifier anyways...thanks a lot bro ^_^

can someone help me why after i change from normal Raycast to Raycast+ it breaks the collision????

[@erro-rh6yd]

This problem usually occurs because the required version to use the Do It with Me file is 4.1+. If you use an older version of Blender to open the file, the Raycast+ node will be broken.

[@VisualistAyush07]

Thanks bro

[@kapheroph]

Thanks for the detail you put into this, great work. I hate to be "that guy" but as soon as I hook the raycast+ node up as per the video I lose collision on the plane. I've been through this video a bunch of times from scratch but always get the same result. Has anyone got any ideas on what I am overlooking? I know it's going to be stupidly simple...

[@tawansunflower]

Happy to help! 😊❤️ Are you using Blender 4.1+?

[@kapheroph]

Oh wow, thank you! Yes, 4.1 and 4.1 Goo Engine.

[@elzibiel]

When I replace the Raycast node with the Raycast+ node, the collisions stop working. Any ideas? I make sure to make all the connections I see in the video here. I just replace the Raycast node with the Raycast+ node as shown and the rain no longer hits the ground target plane, the rain just goes right through the ground even though right before replacing it, i was getting the non-animated splat as seen at 6:09.

[@tawansunflower]

Yea it's the new EEVEE NEXT that just came out. All my tutorials are now outdated. Sorry about that! 🙏

[@tawansunflower]

Did you use Blender that is older than 4.1 to open the file? If so, the Raycast+ will be broken. You will need to move to 4.1, redownload the file, and append the new Raycast+ node. 👍

[@elzibiel]

@@tawansunflower Thanks for the quick reply! Yeah, I was in fact using 4.0. I love that Blender is so well supported but sometimes it advances quicker than I can learn it (just don't have the time) so I stick with a version that I *think* I am getting the hang of. Now your tutorial works as intended. I have a few projects that I might like to have cool drop effects in. Thanks again for the quick support.

[@ubelgameer]

thanks so much for this video tried looking into the racast+ group node and just close it i didnt understand a single line in there wanted to ask if there is anyone who understands the raycast+ or can explain it plssss

[@InfernalInferno6666]

did the raycast + modifier work for you ? cause whenever i try to use it the collision stop working and the splashes dont appear anymore only the rain

[@tawansunflower]

The raycast + node is basically a raycast node with a custom attribute. It shoots a ray according to the "Ray Direction" input and outputs the position what the ray hits the Target Geometry 👍 Now, the Raycast + node also store a custom attribute (data) on each rain point, so when rain hits the ground it carries a custom data which helps the node to calculate the "Hit Age". The Hit Age outputs 0 when the rain have not hit the ground yet. When it hits Hit Age will count up every frame. For example, a rain particle hits the ground on frame 10. On frame 11, Hit Age will be 1. Frame 12, it will be 2 and so on. 👍

[@tawansunflower]

Most problems of Raycast + node not working is caused by Blender version. If you use Blender 4.0 or older it will not work. If you accidentally open the tutorial file using 4.0 and saved over the file, it's too late. You will have to manually edit the nodes inside Raycast +. If you have any trouble on it you can reach out to me via Twitter or Email. It would be better if we talk there. Or maybe I should start a Discord 🤔

Amazing tutorial! I love your presentation. I do have one issue I can't figure out, though... Even after applying your material node setup to each rain and splash object, my meshes look different from the emitted rain. The meshes have the crisp, white outline seen in your video, but the rain coming from my emitter has no outline at all. I've tried adjusting the point and world lighting, and editing the material node of the meshes DOES change the emitted rain, but they still look different... The only difference I could find is that I'm using EEVEE instead of Goo Engine, but my meshes (in the same viewport) look good while the emitted rain doesn't. I'm at a loss!

Hmm I can help you! Can you dm me your shader node setup on Twitter? I'll take a look at it. 👍

Tawan helped fix my issue! I ended up having to disconnect the "age" attribute section by muting the first multiply node it was connected to in the material shader. We currently have no idea why this worked... but if he figures it out, he can elaborate if he wants. I'm just a beginner. 😅
