Dynamica buffer size limit to 5MB?

Post by alek314 »

hi,
I've notice the serializer buffer size of Dynamica is fix to 5MB, and Maya will crash when I try to export a scene big enough.
Here are some questions:

1.Dynamica use btGImpactMeshShape internally, does that imply a single btGImpactMeshShape should be limit to 5MB due to performance or orther reason?

2.How about btBvhTriangleMeshShape? It should have O(logN) performance and a 64MB btBvhTriangleMeshShape should be OK, am I correct?

thanks

We should fix the memory limit indeed, can you file an issue at the Dynamica issue tracker at http://dynamica.googlecode.com?

btBvhTriangleMeshShape query has log(n) performance indeed. The Dynamica plugin doesn't use it (for fixed/static objects) at the moment I think, Dynamica always uses btGImpactShape. This should be fixed too.

Thanks,
Erwin
