Hi, Thanks very much for the plugin!
I'm only starting to familiarize myself... is there a roadmap / todo / in progress / plan for Dynamica? It's already quite neat, but there is so much potential for it; I realize the first thing is going to be more robustness (I'm trying to identify some of the bugs I encountered to be fully reproduceable) and artists will want features like cache / bake, set to initial, etc. (some things can be done in MEL, I'll put some together). Perhaps more of Bullet's built-in features can be folded in? More shapes, like heightfield, constraints, motors, sleep+threshold, etc. sound nice.
Oh, as a side note, this is most likely not Dynamica, but the Bullet engine itself: I noticed sphere primitives are a little unstable together. It's funny because mesh spheres appear stable, but it seems primitives should be more efficient. Sphere primitives tend to crawl and spin when they are put together, a quick minor example with only two spheres in Dynamica:
move -y 5;
move -y 10;
The top sphere will crawl away from the bottom one after it lands on it, when I
play it anyhow (using the 2.71 rev3 binary posted here). If this is normal, fine, I was just surprised given how stable all other shapes were.
