<div>I was there during the physics meetings on this on Agni.. The convex hull checkbox turns the physics proxy into a shape much like if you were to wrap plastic wrap around the object. Unlike the current functionality, it doesn't split them into multiple convex hulls to approximate the concave areas also.</div>
<div> </div><div>The other options are physics approximation options.</div><div> </div><div>The general purpose of these options is to give the content creator the option of reducing the physics load on the simulator which would normally be tri-mesh.</div>
<div> </div><div>Also.. where we mesh sculpted prim, Agni, traditionally has been a spheroid.. but I believe that the items are controllable with scripting and/or a drop down menu with the right cap response to the cap that expresses what features the simulator supports.</div>

The "Universal Hinged Motion in 8 Key Frames" is useing<br>
<br>
llSetLinkPrimitiveParamsFast(LINK_THIS, [PRIM_PHYSICS_SHAPE_TYPE, PRIM_PHYSICS_SHAPE_CONVEX]);<br>
<br>
It seems opensim dopnt support [PRIM_PHYSICS_SHAPE_TYPE, PRIM_PHYSICS_SHAPE_CONVEX] as setting ?<br>
Time to dig my own example script up....<u></u><u></u></p>
