I love the way you explain things, you are very good at it. I have a question: I bought the addon and play around for learning. I have a domain and an inflow object (UV Sphere). I parented the inflow-object (UV Sphere) to a bone. The inflow object correctly moves with the bone, but it's emitting static. It looks like the liquid is not even emitted from the UV Sphere anymore, it doesn't move with it. So I searched a bit and found the option "export animated mesh" within the inflow object. But when I activate this option and bake again there's nothing to bake. Nothing happens, there's no liquid emitting anymore. So do you know how I could approach this to get it working? I love the addon so far.
Export animated mesh on your inflow should work. Would it be possible to send us you blend file to our support mail adress? Thank you for your kind words- really appreciate it.
@@FLIPFluids Thanks for your reply ;-) I will play around a bit more and will mail you if I don't find a solution myself. Have a nice weekend! EDIT: Last question just to clarify: If i use the option "export animated mesh" I don't have to do anything else, right? It will do this itself?
Quick tip for repeating the sequence continuously: "Shit+E" in the Timeline -> "Make Cyclic". You will have it with one click instead of doing the useless graph editor stuff. Great video tho !
We cannot guarantee that our addon will work in the way you are talking about in the future. However, we are doing our best to make it better and more feature rich!
I guess the main issue I've been running into is that fluids don't stick to an object very well. I have a mug full of fluid and when the mug moves, the fluid just flies out. I tried adjusting the viscosity (set it to 2.5) to see if that might help and the issue still occured
The only things you can try is to increase the obstacle‘s friction- and for some scenes using sheeting can help for some effects. You could take a look to our slime assets.
I was wondering about using changing displacement modifier on a volume force, I did as such, but the mesh of the volume force did not have any changing field lines and the changes in the fluid did not reflect the changing mesh of the volume force.
Thank you for this video. I would like to ask you about the falling cube from the stairs, when I bake the rigid body cube falling simulation, then bake the fluid simulation inside the cube, the fluid will stay at its position, not falling with the cube. How can I fix this issue? It seems that you did it successfully in this video.
Hi! Make sure, that the rigid body simulation is baked. And also enable the „export animated mesh“ checkbox in the object‘s settings. If this does not help, please send your blend to our email address ;)
everything is working, except when i go to render i get a lot of flickering. this only happens with the whitewater foam visible in the render. any ideas? im using the default FF materials for everything
@@FLIPFluids so i tried the cmd rendering, which is a nice feature, but i noticed the issue coming from the whitewater_foam particles. if i turn them off, no flickering, or if i enable particle instancing, the flickering goes away, but the renders are way slower
Hi I bought your addon but I can't understand what the problem is. From the object inflow after it is switched off water does not flow as I need, BUT afterwards the amount of liquid increases from itself. HELP me please, I can not solve the problem
I am facing a problem. I'm parenting the Inflow with a moving Obstacle, but the fluid come out of the Inflow Object doesn't follow the Obstacle. How can I fix this?
my fluid is still passing though my obstacle, ive enabled the debug and also increased my resolution, although i am a beginner, what i am doing is very simple. ive spent hours on trying to fix this problem. i just want my obstacle to contain the liquid and add simple rotation animations. ive searched everywhere for a fix but nothing works and i cannot increase the thickness of my object or it will no longer look how it needs to.,
Hey there could be different reasons: 1. did you check for non-manifold data? your obstacle needs to be watertight. 2. is your object patented or using complex animation data? In this case you would need to use „export animated mesh“. 3. Is the resolution high enaugh to work with thin objects? You can also use our support form or discord to send your blend file and we check it for you.
Hey, I came accross an issue when obstacle which is parented to an animated empty is totally ignored by fluid. Problem disappears when I animate object itself - but in the scene I am making this is not an option because of attached constraints. How to workaround this. Thanks!
There could be different reasons for this. Is the cup "watertight"? Try a lower CPL number (advanced settings). And use sheeting (world settings). Let me know if that helps.
After adjusting CFL I’m still losing a ton of fluid volume. I’m trying to create a bottle with fluid in it. It works for a second and then starts to drain out. There’s got to be a fix for this!
@@FLIPFluids I‘be tried both a thin bottle and solid bottle. They’re both draining out. I added a volume force field using an icosphere and that has helped a little. But it’s still not perfect. Unfortunately, the bottle has to be moving with liquid sloshing around.
I've experienced objects with ample size, and high res domain settings, not emitting fluid nor colliding. Much smaller non imported geometry do emitt fluid and collide in the same domain.. Normal appear to be ok. remeshing doesn't change a thing. Any ideas on fixing this?
Hi, I'm using Blender 2.92 and 2.93 and Flip Fluids version 1.0.9 and I get the following error message when I hit the bake button- AttributeError: type object 'array.array' has no attribute 'tostring' I am clueless as to what's wrong and how to fix it. Please help.
Hello! The best way for us to help you is if you would send your blend-file to us. Also a screenshot of your user preferences with the addon selected would be great. Send it to support(AT)flipfluids(.)com
Hey I have a problem, I would want to doanload experimental built but I don't know how to do it, because on your website it says that it's on blender market, but I can't find in here either... So can you help me plz😅?
Just checked this. When you are logged in into your market account the experimental build can be downloaded (as long as you purchased the addon). There is no other way to get an experimental build.
It the same issue as with non emitting fluid - you need a thicker obstacle or finer simulation grid. Debugging helps you in finding out. Please watch the 10 Tips video - it explains exact this.
can someone please tell me how you would change the settings to how much liquid comes out ? aswell as the boundary box in vanilla, where it just goes out instaeed of filling the domain? Im trying to make a river but i cant figure it out, all videos seems to be about the same thing :( i tried using a box for outflow, but it didnt seemt o work to avoid it fillin the box, since i onl want it to stay in the river)
it says there is baked frames (nearly 18,000) but when i go to try to render it the fucking frames are not there there is NO fluid simulation i am PISSED .. if it is simulating I EXPECT TO SEE THE RESULTS
Hi Ponlets we are sorry to read you having issues with using our addon. Would you please send your blend file and Some system information to us? Read the guidelines for customer support on our homepage.
@@FLIPFluids well i mostly managed to figure it out but ended up not using FLIP Fluids in my recent animation because it took too long to do 17,300 frames (roughly 24 hours)

Will it ever be possible for this addon to not generate poles? Poles make fine fluid look almost spiky when trying to make it smooth.

Would be helpful if you please do a tutorial on water jet spray using flip fluids/Mantaflow.
they do that in this video
@@michaelwaxter9622 no they don't... they use Flip. Manta flow is a diff. solver

Yep that’s right. Export Animated Mesh is required.

can you help me ? fluids ignoring my obstacle when it has no thickness. How can I fix it without using solidify?
It is not possible to simulate an obstacle without thickness.
But you can add solidify for the simulation and after this you disable it for rendering.
Why am i not seeing any particles at all. I upped resolution and baked. Nada. Using Blender 2.93. What am I missing?
Maybe they are disabled for your viewport? Or did you forget to enable whiewater before baking? You could also send your blend-file to us.

This sounds more like a problem with thin obstacles than the volume loss issue.
Try to use thicker bottle for simulation and render with thin bottle 😉
