Yes, in the sense that it doesn't know anything about it and lets Opensim run it on the server side (which is always the case with such physics currently in SL and Opensim). Like mentioned in the other post, iirc you must make the 'prim' (sl talk for a scene object in general, not only ones made with prims but covers also meshes and everything there) physical. I visited OSGrid's nice recreation plaza with my build of Naali 0.4 now, but unfortunately have something amiss in that dev build 'cause build mode didn't open .. and there are no prebuilt binaries of old versions for the new ubuntu 11.04 now. Am rebuilding with worldbuildmode enabled, otherwise can test on some other machine later. EC editor showed some of the prim params (the shape), but iirc others are in the properties tab (which is special opensim prim things, outside the generic EC system there). In SLviewers GUI the physics properties are called 'Physical' (gravity affects iirc) and 'Phantom' (whether other things collide to it or not), are in Object tab apparently. Am now visiting the same recreation plaza with Imprudence so can see that. IIRC Jonne put the things to the build mode properties tab, if it doesn't have all the flags is probably quite easy to add the missing ones. Like mentioned in the earlier post, the EC based EC_RigidBody is not in 0.4, and even if you'd use newer Naali/Tundra which has it, there is no implementation of that on the Taiga/ModRex side so it wouldn't actually activate the opensim side ODE physics. However, if you want client side physics in Naali for some reason, it would be possible to adapt the PhysicsModule from later versions and then the generic EC system which already exists in Taiga would just store those properties on the server .. and clients could run physics with Bullet. But I figure you want the server side, so just using ODE there like normally with Opensim is the way .. i.e. enabling that 'physical' flag (the physics engine is enabled by default in opensim.ini in taiga). > yaoyansi ~Toni -- http://groups.google.com/group/realxtend http://www.realxtend.org
