Creating small splashes from POP collision detect (or something simila

[nico_venster]

Hello,

 

CONTEXT

I have a scene in which a character is painting a floor. The paint is transferred to the floor as points and converted into a VDB and then geometry (to fit the style of the film).

 

Here's a video of the scene I'm busy with: 

 

QUESTION

It would be nice to get some secondary splashes when the character slams down the brush (and randomly when he paints on the floor). My initial thought was to source the brush geometry, and give it a pop collision detect (for the floor). Then replicate the points with an initial velocity, mesh them and presto. A couple of problems though:

 

1. I want the particles to emit only now and them (randomly essentially) and at high impact times.

2. I would like to set the directions of velocity to match the animation.

3. With the pop replicate the shape of the splashes wouldn't look ideal

 

The scene and its alembics are a bit large for the post :/

 

Thanks
