Blender rigid body simulation

I'm trying to set up a scene in blender with a "bank vault" like room full of gold coins. Now I could just make copies of a coin object and manually place them but I do not have the patience to do that... so I'm trying to setup a solid body simulation. I've taken a coin and made it an actor. If I solve the simulation now it works perfectly, that one coin falls to the floor. I can't seem to make stacks of coins and drop them. I've tried to create an array of coins and drop them. I've made an array of the coin object that would cover the floor of the room just fine it's just that when I solve the simulation it only solves it using that first coin objects not all the objects in the array. I can make duplicates of the coin which does copy the actor data assigned to the original coin but there is a chance I'll have some overlapping coin objects that may cause issues. Any suggestions?

Try to convert the array to real objects.

In other words click apply in the array modifier window thing...

and then, set your soft/rigid body settings on the mesh, then enter edit mode, press P and choose "all loose parts", to create many objects with the same dynamics, materials etc settings.

I'll give it a try. Thanks.

Thanks all! That works wonderfully! One more quick question. Because I don't care the path the coins take just their final position, is it possible to run the simulation until I like the results, stop it somehow and render as is and not have to bake the sim to IPOs? Just running the sim takes less then 30 seconds

nope :)

Try lowering the frame-rate in render settings. Not sure if it affects the sim but you may as well try anyway :roll:

disable all frames, if thats not disabled already. Then like Anthony said, you just gotta bake to ipo and go to a frame where everything has fallen.

you mean "uncheck ""enable all frames""" I guess? ;)

to increase simulation speed, you could increase the gravity, as the frame count wont matter ;)
