Help Smaller emitter scale and particles

[josemendez]

Hello, I've got a problem with Obi Fluid, especially with emitting a tiny track of fluid.

Main problem is that I can't set emitter radius as small as I'd like to. When I reset all scripts or add new emitter, solver etc., it works perfectly fine.

But ... when I start decreasing radius of Emitter Shape Disk, it starts to throw particles around or particles become invisible. I also tried to change params as resolution in ObiEmitterMaterial or Radius Scale in Obi Particle Renderer. Even rescaling emmiter by transform didn't work well. 

I noticed that by changing value in params I mentioned before, spourt of fluid becomes drops which are emitted separately.

Any idea how to create tiny track of fluid ? Thank you, in advance, for answer.

Hi there,

Decreasing the radius of the emitter disk won't affect the size of your particles, only the size of the emitter. Neither will changing the radius scale in the particle renderer, quote from the manual:

Changing the radius scale does not affect the actual physical size of your actor's particles. It just draws them bigger or smaller than they really are. They will still use their real radii when involved in collisions, fluid interaction, etc.

To change the size of the fluid particles, either increase the fluid material's resolution, or use local-space simulation and scale the solver down. See:
