Awesome - just pulled the latest dev revision, that static mesh demo #10 is impressive.

Been composing my scenery with groups of kinematic boxes so far - I'll try a StaticMesh again with the new dev build and let you know how it goes.

Got some really nice results using ConvexHull, the collision handling seems really solid on that - so I can probably just divide my scenery collision meshes into convex pieces. Would some kind of ConvexHull + binary space partitioning be a good way to handle StaticMesh's internally I wonder, or are ...

Interesting, thanks - I tried scaling by everything 5x, enabling continuous position updates, leaving AllowedPenetration at 0.005, and setting the collision margin to .1 - the tunneling problem was much improved (I'm assuming that refers to things slipping through the mesh). Still a lot of planks ro...

Hey - Wanted to get some advice on getting a StaticMesh to reliably prevent entities from falling through - I've searched the forums a fair bit and tried some of the suggestions from earlier posts. You can see the behavior in this test vid: http://www.youtube.com/watch?v=qvt0i1_DuLk Main problems ar...

Thanks - ended up writing a static utility method that calls that AddMesh() method, worked good.

Just a quickie suggestion - the static method on TriangleMesh to get verts and indices from a Model is handy - would be cool to have one to read in vertices for a particular Mesh too, for models that are parsed apart into different pieces.

And thanks in general - brilliant piece of software.

Excellent, that did the trick - getting repeatable results now without employing the "nuclear option"

Somewhat sneaky but this works:

You're right - did a little digging, I was able to get an exact repeatable simulation on a level with just box entities by reinitializing the box-box pair handler factory when I reinitialized the space: TypePair boxPair = new TypePair(typeof(ConvexCollidable<BoxShape>), typeof(ConvexCollidable<BoxSh...

Interesting, thanks - was brainstorming some weird workarounds like reloading the BEPU assembly each simulation run, but will wait to hear back (sounds like that might not tackle it if it were due to hashCode sorting etc., and I'm sure it'd be fun to get working on the xbox

One other note, related to memory allocation - I made a very bare-bones "determinism testing build" to try and eliminate anything that my game engine might be doing to interfere - I noticed in CLR profiler that disposing & nulling the Space and triggering garbage colleciton didn't free...

Hi - I'm working on a physics-based puzzle game that involves destructible objects - I'm having trouble getting the simulation to be repeatable though - it's important to this game, as some levels will have a rube-goldbergness where small variations can mess up the final result, so the user would ha...
