I tried your file in both R18 and R19 and see the same thing that you referenced: the fracture objects disappear at frame 701. I don’t see any obvious reason why, but I haven’t had time to dig in deeper. I’ll let you know if I can find an answer.

Post the project file to see if anyone can duplicate the problem.

Assuming that you set collision noise to 0 for both tags (floor and model), unless the model isn’t falling straight down (it has some lateral velocity from an impact, for example) it should just stop in place once the bounces end. Since it sounds like you are trying to recreate the actions of objects in a game, which don’t act realistically (which is what dynamics is designed to do), the easiest solution may be to just keyframe the position of the model as if it is falling to the ground.
If you can’t get it worked out post a project file and I will take a look at it.
(Just for clarification, I only placed the sphere over the model in my example to show how I adjusted its size. Its position is irrelevant as it is only being used as the shape for the collision.)

There is no way to smooth (make less snappy) a “transition” between two adjacent frames because there is no transition. What you need to do is to create intermediate frames — what the head would look like in-between the two positions — so that there is a transition between the first and final positions. The more you have, the smoother it will be. Rather than drawing the frames yourself, make the layer 3D so that a quick rotation will give the illusion that the head has thickness.
Edit: I was writing my response while Blaise’s was posted.

It’s interesting that you also get it on a PC and Adam does not. Must be related to Windows version as well.

You could use “Another Object” as the Shape in the model’s collision tag, and enter a sphere as that object. You will need to set collision noise to 0 for both the floor’s and the model’s collision tags so that the sphere shape doesn’t roll. And since the model is using the sphere shape and size for collisions you will need to adjust the size of the sphere so that its diameter is the same as the diagonal of the model, otherwise the model will appear to rest with its edge above or below the floor. Hide the sphere by turning off its visibility in the editor and renderer.



I hope this helps.

Okay, thanks Brian. I guess it’s a Mac bug.

Thanks Adam. I can definitely work around it, but it’s a bit annoying.

I’m not sure that I understand the question. If you are trying to delay when the object falls you can keyframe the Dynamic setting Off, and then On when you want it to fall and bounce. If that’s not it, please provide some more information.
