I'm not sure, but I think the implication of this is that it's difficult
to make, say, even a simple 1 room complex set using mesh (in something
like SketchUp or Blender) and then get it to behave properly in Second
Life, as you need the interior spaces to "work".
Has anyone had success importing mesh closed rooms or buildings into
Second Life?

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.
The other options are physics approximation options.
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.
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.

BulletSim uses convex hulls for all physical objects. It does not
use the convex hull that may have been defined in the mesh but it
generates an approximate convex hull using the HACD algorithm

What do you require of the convex hulls?

standard opensim with ODE physics does not support convex hull
collision shapes. I believe BulletSim does but I don't know if
it's been extended into the LSL API.

i just wanted to try a default example ofllSetKeyframedMotion
script on http://wiki.secondlife.com/wiki/LlSetKeyframedMotion
The "Universal Hinged Motion in 8 Key Frames" is useing
llSetLinkPrimitiveParamsFast(LINK_THIS, [PRIM_PHYSICS_SHAPE_TYPE,
PRIM_PHYSICS_SHAPE_CONVEX]);
It seems opensim dopnt support [PRIM_PHYSICS_SHAPE_TYPE,
PRIM_PHYSICS_SHAPE_CONVEX] as setting ?
Time to dig my own example script up....
