Particle doesn't emit from dynamic paint

Hi, I am trying to emit particle from dynamic paint. The brush is another particle system. I enable dynamic paint output vertex group and use it as density for emitting particle, but is doesn’t work.:spin::spin: Thank you .

Blender file

Anybody? Please help, or it is a bug.

You need to move the dynamic paint above the particle system on the canvas, and enabled ‘use modifier stack’ in that particle system. I think you’re looking for something similar to this.

Thank you every much, it works. One problem though why particle from canvas appera before particle from brush hit the canvas?

Yeah they sure are, hmmm, not sure on that one. Sorry. :frowning:
