RF mesh interpenetrating bottle geometry

Post by pistolsloaded » Tue Aug 31, 2010 6:35 pm

Hello out there,
I'm making a simulation of a half empty bottle bouncing off of a floor.
Bottle was animated & baked out in Maya, brought in to RF4.
I've created an emitter inside the bottle, let it rip for awhile, turned it off.
I then let the particles settle a bit, then ran the simulation.
The particles themselves simulate beautifully.
When I create the mesh, it almost works - that is, it basically ignores the mesh of the bottle, popping through at times, not at others.

I've adjusted the bottle's collision distance 10 or more times - even when cranked up interpenetration occurs (though the mesh floats apart from the bottle geometry unrealistically.)

Am I missing a setting on the mesh that tells it not to ignore the imported geometry?

Any help is much appreciated

Thanks

Basically, yes. You need more particles, that are closer together.

Search the forum, there are a number of "liquid in bottle" threads that have encountered the same problems. Lower your internal pressure, up the resolution and you'll find you can get a much tighter mesh that doesn't interpenetrate the object.

Thanks for the reply. Looks like scene scale was the problem.

Cheers
