A number of questions on the Blender Fluids simulator.

I have been working with blender for a number of years now and have never really experiemented much with the Fluid Simulator. So I have a couple of questions.

  1. How do you get rid of that annoying gap between the surface of an obstacle and the fluid?

  2. Is there any possible way to have 2 fluids in 1 scene. So you can do mixing paint animations or something similar?

  3. How do I find out the max resolution my computer can take?

  4. Are there any other ways to make the fluid look better, other than “set smooth” and increasing the resolution?

Thats it, question #1 is my most important, hope you guys can help me. Thanks!

  1. You can’t completely. Increasing the resolution reduces the gap. This is a symptom of how the fluid simulation is calculated. You can fake it though. The obstacle doesn’t have to be the object that you eventually render. You can include objects that do not interact with the fluid and duplicate ‘obstacles’ which are slightly moved so the fluid looks like it interacts with the rendered objects. Hope that makes sense.

  2. You can have multiple fluid sources but you can only have one type of fluid.

  3. Increase your resolution. If it takes too long for you to wait for it to calculate or blender crashes, the resolution is too high for your machine.

  4. Make sure you have the realworld setting correct


oh ok, thanks, i will take this into account next time I am working with fluids. thanks heaps.

Hi There
