xpFluidPBD banding

Recommended Posts

hi guys

i've got a simple waterfall setup using xpFluid, an emiter and collider for the waterfall.

i'm getting a very strange banding once the water falls over the sides. see image

you can see when the particles fall over the edge (on right side view) they are very clumped into rows.

what is happening ?

you can see my xpFluidPBD and Emiter settings in the screenshots.

any ideas?

two things I would try to change:

1) from rate go to hexagonal output

2) even more important - in project settings rise subframe steps and iterations


pics - first default settings, second subdivisions 4 and iterations 6, third, hex output with same project settings
