Delaying time of Rigid Body?

[Steve Bentley]

Ah I see, its an approach difference. (at least it appears to be). When we use real flow we make a batch of .bin files
in RF (basically OBJ meshes for every frame). These remain outside C4D (keeping the file size down) and we use the plug in that comes with RF to load them into c4D. This lets us change out the mesh after the fact without upsetting the project.

In your case (I think) you are loading the fluids right into C4d (which is fine). But here’s what i’m wondering. Because the meshes from RF aren’t actually moving in time – each frame is a snap shot of where the particles were in RF – I don’t think they are going to react properly to the dynamics engine. That engine is looking around for things your earrings need to collide with and suddenly, on the next frame, out of now where, the earrings are suddenly touching or embedded inside a blob of liquid. The engine will say “where the heck did that come from?” The mesh from the previous frame wasn’t approaching the earnings and wasn’t in danger (on that previous frame) of running into the earrings so the engine would have been oblivious to it.

So I’m not sure the dynamics approach is going to work.

What you could do is make a blobby object that approximates the fluid movement and you hand animate it to be a collision proxy (or as we call them around here – stunt objects) or make a particle/mograph system inside C4D that travels like the one from RF does, but it doesn’t need to be high a resolution and it wont be used in the render. This particle system is used as a proxy to trigger the crown splash when the earnings intersect the particle stream.

I’m looking at it now.

I’m unfamiliar with the how-to’s of Mograph as well as “stunt” objects- I’m familiar with building a “cage”, is this the same? :/ I doubt it since you lost me at hand animate. Regardless I did build a cage and apply the same tags on my earrings over to this cube fit to envelope around the earrings, set to x-ray mode. (removing the RF Collider body tag from both earrings, keeping rigid body) I rendered the animation once and no crown splash result but now I am trying again ..except this time I made the cage editable? Doubt that will work.
However I’m very curious about this mograph system and matching it to real flow. Yet I have not a clue how to begin doing so.
Any suggestions?
