Is it possible to have the jme3 physics use the actual mesh of the geometry? The reason I ask is because my mesh is being copied for the physics part, adding another 200mb to the memory useage. For some reason the jme3 Vector3f takes up less memory than the java math Vector3f.
No
Your mesh is 200mb? :o
whats a mb?
motherboard of course. dummy ^^
The reason is quite simple, jbullet is written with vecmath and noone has the time and fun to convert it to jme3 vectors, and native bullet needs the stuff in c++, so no way.
Anyway 200 seems way to large for some reason, what are you trying to do with that?
