    It took me like 3 days to figure out most of the stuff that was mentioned in this video.
    While there's no official documentation on the manual about how to troubleshoot the issues, this video will save you a lot of time.
    Great stuff, thanks for this!

    At 1:00 Select "Is Planar" option for planes ( I believe this option is for planes cuz when i selected this option, it worked well) It works for cylinder or cube which has no thickness

    My Fluid simulations never work, I add a uv sphere then then select fluid, then change the settings to liquid and inflow and domain resolution to 64. pretty much the same setting you use and see no particles when i bake data. this happens everytime

    • @mumkichux
      @mumkichux 3 года назад +1

      you also need to change setting in domain and flow. Otherwise just select the uv sphere and then in object tab or search quick fluid that will work

    Thank you! 👍🏼 It did not fix my problem but at least now I know where it comes from. Another thing to mention for fluid sims with mantaflow: I never got a proper result when I tried to use real life sizes. I had to make a 60 cm wide cup to be able to 'splash' the fluid in a realistic looking way.

    @flipnap2112 4 года назад +2

    experimenting with blender. been using Maya since V1 (for my job) and Fusion for fun. also an old after effects guy. Problem with blender and learning is that they change so much with every iteration people get confused by watching tutorials online. example, it looks like they already changed 9:23 for the "bake all" part, from "type:final" to "type "all".. not sure why they would change something like this, when "final" made perfect sense. not entirely blenders fault, its just that people are following older (and by older I mean maybe months ago) tuts that are outdated and not working. this program is SERIOUSLY trial by fire. I've spent so much time doing tutorials over and over and over just trying to get a result. its a bit overwhelming. When I first started using fusion it was predictable and results were the same every time. they barely changed up the important things (UI and UX stuff) and it gave some continuity to learning.

  • @dinoschachten
    @dinoschachten 4 года назад +4

    Very nicely laid out! I would argue that bringing up the surface thickness is not always a nice way to go as it makes the fluid not touch your collision object anymore, but your explanation is very helpful to understand glitchy behaviour. :)
    More often than not I think it comes down to creating realistic objects (nothing in our world is 2D after all) and bringing up timesteps as you mentioned.

      @TheDJkarsy 3 года назад

      @@razz6539 Hmmm, that was a long time ago but if I remember correctly pumping up the resolution size helps create smaller fluid particles. But of course that increases bake times. I would suggest getting Flip Fluids if you can afford it, I have been using it since and it is much better but it is pricey.
