Hello,
I am copying the sample rigid body file and replicating every single node and parameter on a new layer and I am still failing to get a rigid body animation. Is this a limitation of the PLE?
There is no limitation in PLE for such functionality, have you checked the rigid bodies samples available in Notch startup?
I’m having a similar issue here. Opening the samples works, but building my own rigid body system (even on a brand new file), is leading to this result. It was working, my program crashed, and as soon as I returned, I get this result. 
Any tips here to get this back to working?
welp, I sorted it out- just a stacking order issue between the two effectors!
