Hello,
I have been trying to create a particle system that’s just a load of wads of cash piling up. I have created a simple wad of cash model, a floor (plane) and an emitter (plane subdivided into 36 faces so I can emit from each point). I’ve made the emitter emit Newtonian-style and I’ve made the floor a collider object. So far, so good - the wads fall out of the emitter and hit the floor and stop. But they don’t pile up on each other. I’ve seen several tutorials about arraying my object, applying the arrays, separating the objects and adding a rigid body modifier…but surely there’s a way to emit rigid body particles from a particle emitter, like in every other particle sim system…isn’t there?
If I add a rigid body system to my emitter, the whole emitter just falls down onto my floor!
This cannot be done in Blender without an addon. But there is in face an addon for it: molecular+. It adds collisions to particles.
In default Blender, the closest you could do is use the fluid type particles, but that will at best react like a thick goo, not like rigid bodies.
An other option is to not use particles. Do the whole thing using rigid bodies. The issue with doing it like this is that rigid bodies cannot be spawned, so they need to all exist at the beggining of the simulation.
Thanks - as I suspected, I need to just duplicate a whole load of my wads of cash and do a rigid body sim, which is exactly what I have now done. Just seems really odd that this is not possible in Blender. Oh well!
Hi, Thanks for the info’. i was quite surprised that blender particles not able to use the rigged body sim. Anyway i have downloaded the addon you have suggested and tried to open it in 4.1 but i have got this message?:
I have to admit I didn’t use the addon, I just knew it existed and have seen people use it. Maybe it’s already broken? Addons sadly don’t tend to last very long in Blender if they aren’t maintained.
Nice simulation, though something feels a bit off about the way they roll on the floor. Are their origins centered?
It’s weird how they fall at a normal speed at the beginning, but once on the ground they flip really slow. I don’t get this doing rigid bodies with the default settings. Is the scene at a realistic scale?
