This in an Introduction into the procedural rain generator, what means it shows how to use the assets and the geometry node settings. Please make sure to work with the mentioned high resolution for the simulation (it can require more than 800). If there are any issues please send a support request including your blend file so we can help with your scene :)
Sorry to read this. It does also not make any sense to try to help without taking a look into your file. Would you please send your blend and some information using the support form on our webpage? That way we can help you :)
Hello! I am new to blender and I just recently brought this add on, by any chance you could do more a in depth tutorial for simulating the rain. Sorry I recently transition to using blender not long ago as I was used to using more the Autodesk maya.
@@FLIPFluids Hi Thank you for replying back to me, I was wondering how you made the monkey interact with the rain pouring down? so you showed loading the object but it wasn't clear how you finished the whole simulation.
The monkey needs do be watertight- always check for mommanifold data. Then use it as obstacle. Maybe increase friction. Make sure to use a higher resolution and some surface tension.
Hey there! Thanks for the awesome plugin. I'm having trouble getting started though. When I drag the rain get domain into the scene blender immediately crashes. On a i1900k cup with 120gigs of ram. RTX 4090.Thanks in advance!
For those who can't (don't understand) why nothing works (including RTX 4090+). 0) Use small cube like Suzanne 1) First of all, check the Resolution! By default, it is 950 (this is too much even for powerful hardware, set it to 200, or even better, 100 for testing). 2) In the min/max droplet settings - set the scale to 0.05 and 0.08 (for example, i.e. a value closer to 1 (big particles), because the default settings are very high). 3) droplet rate set it to 20, not 5000 (small amount). 4) And now you can click Bake. Try with these parameters, then you will understand which way to turn to get the best result.
For some reason, when I hit bake, the result still looks like the "noise" of droplets popping in and out of existence just like at 2:41. I followed the tutorial exactly as seen. just to test and still could not get it to work. There doesnt sseem to be any persistence to the drops, or gravity to pull them down. What am I doing wrong?
Hi! I'm using blender 3.6.2 and even tried with 4.0, when I bake it I got the same result as "noise" like, the rain is not dropping down...@@FLIPFluids
Hello! Thank you for this tutorial. :) I have a question... I'm trying to use the Rain Gen to simulate rain dropping onto a rock wall and trickling down in a large rain scene. Is there a tutorial that I can follow that would best guide me to this result?
I don’t know any tutorial. I think surface tension could be helpful. Dynamic Paint and wetmaps is also a thing to take a look into. For some solo drops i would not go with a simulation. Depends on your requirements. You could send a prepared blend file to us and we take a look into your settings ;)
@@FLIPFluids Thank you for the reply! I will see if I can fine tune my scene with the instructions you have given. However, if i'm unable to achieve the result that I want, would love to see if you have a solution. What is the best way to send over a blend file for your team to look at?
Would you know a way for blender to stop crashing every time I try and add something from the asset browser. I'm running blender 3.1, do you think that could be the problem?
Yap maybe! Using the latest version of blender and the Addon could help. If not feel free to send a support request using our online form and we will be glad to help
We recommend to try this with our free demo version. Highres should work without any issues. But it also depends on your system configuration. Let us know id you need support in creating a scene.
Hi there. I got the Flip Fluids package primarily for this awesome rain generator in Blender. I have a good machine for 3D with a Ryzen Threadripper 3960X CPU 24 Core. However, bake times for the suggested Suzanne scene shown (at a high res - 950) are extremely long: days! Can anyone tell me what a normalish bake time for this scene should be or better, what their experiences are with this simulator. Thank you. 😎😎😎🌧🌧🌧🌧☔
Hello Tomurow! The rain generator can only run in a high resolution as each generated drop is very small compared to domain-size. Unfortunately this results in long simulation times. We recommend to use this generator only for small scaled scenes (as example close-ups where rain drops are moving over a surface). For bigger scaled scenes a regular particle system or rain generator addon would be the better choice. Of course - you could combine both ;).
@@FLIPFluids Thank you or the quick reply FF Team! That’s good to know. Yes, that’s exactly what I’m doing, so that’s cool (I also have the Baga Rain Sim for large scenes - works great!!!👍). I suppose I was looking for a benchmark but I guess it’s gonna be a demanding simulation as you have described! The results look great though. I will commit to a bake when I know my machine will be in limited use! Thanks again! 🤓
No - the small drops need a very high simulation resolution what decreases the speed. You should use a very small domain and use the raingen only in areas where a real rain behavior is required. For all around we recommend to use a regular particle system.
hello dear Flip fluids did you correct that issue on your addon in Blender ! when using keyframe of slowmotion and simulation itr missedUp !!! for example : im doing simulation , its oky i like it now i want to freeze some frame when i want to see water or milk splash the bottle when i use thos keyframe in your addon , the simulation gonna be differente can you correect this issue please !! im waiting for your update of this issue thnx .
You would need to Keyframe the simulator‘s speed as well - otherwise it keeps simulating with the real time. A speed field is available in the domain settings. Let me know if this is helpful.
I am new to this flip fluid add-on, I tried the rain generator preset, but I am receiving some warning message. Crash warning: "Whitewater attributes:-Velocity." and I do not see the output.
Thank you very much. I am trying to use Flip Fluid for real-word application. can you provide a email address so I can send my trial file. Thank you. I truly appreciate it.@@FLIPFluids
It sounds like to need a higher Resolution for simulating the small drops. If nothing helps please share your blend file with us. We can then check what’s going wrong.
@@FLIPFluids seems rendering my animation out with CPU instead of my gpu has fixed all of my issues…. From random frames where all of the geometry and particles vanish, to the motion blur going whack, to crashes after crash… this plugin does not work well with GPU rendering at all. But seems just fine with the CPU
Just checked this. It´s there. Please make sure you have downloaded the latest version (1.3.0) and unpacked all files in your assets-directory. Check also, that you set the right path in the addon´s preferences.
@@FLIPFluids Where? I logged into my Blender Market account where I bought FLIP fluids. I don't see anything about a rain generator. There is nothing to download except the initial Addon.
I was struggling to find it as well. So the Rain Generator is located within this file "FLIP_Fluids_Addon_Presets_v1.2.5_(25_sep_2023).zip" that is 1 of 6 downloads where you downloaded the Flip Fluids add on. @@tgs1766 Hope that helps
