Glass of Scotch

Postby MrFluid » Sun Sep 15, 2013 7:00 pm

Hey guys,

I'm working on a little project with scotch pouring into a glass. I want to add ice cubes in the glass and have the fluid interact with and move the cubes as would real liquid would.

Is there any way to make the ice cubes in RF dynamic objects that have buoyancy?

Hi,

yes, that is very well possible. Look for the "Particle fluid interaction" tab of the ice cubes, then turn on "impulse" and increase its value for stronger floating and interaction with the liquid. The ice cubes as active dynamic objects.
Maybe you have to reduce the "mass" parameter of the ice cubes.

Christian, couldn't I also use an emitter to clone my ice cubes to drop into the glass and interact as well?

Such things are possible in some 3D applications, but not inside RF. Dynamic cubes could be created using a python script, but not with an emitter.

Christian, I'm having problems with this. 1. How can I change the mass of the object? I do not see an option for this. 2. does the collision normal in the interaction tab need to be set to outward or inward? Thanks

What does it mean when you get the error, possible encrusted objects?

The mass parameter is in the rigid body settings (see pic). The normals should point outwards.


"encrusted bodies" means that there might be overlap of some rigid bodies, but this error also appears if the bodies are only close together (and can be ignored most of the time).

I see. is that rf2013 or 5? I can't seem to locate the mass parameter within the rigid body section.

Got it! Density = Mass. it's moving now!
