RBD problem, static friction

[Francois Lord <francoislord(at)gmail.com>]

Hi list,

I've never encountered this before and I'm quite surprised to see it 
doesn't work properly.
Here is a little script. How do you make the active object follow the 
passive one, while keeping it active?

[jscript]
CreatePrim("Cube", "MeshSurface", null, null);
Scale(null, 1, 0.1, 1, siAbsolute, siPivot, siObj, siY, null, null, 
null, null, null, null, null, 0, null);
CreatePassiveRigidBody("cube");
CreatePrim("Cube", "MeshSurface", null, null);
SetValue("cube1.cube.length", 1, null);
Translate(null, 0, 2.2243411755899, 0, siRelative, siLocal, siObj, 
siXYZ, null, null, null, null, null, null, null, null, null, 0, null);
CreateForce("Gravity", "");
ActivateObjectSelTool(null);
SelectObj("cube", null, true);
ActivateObjectSelTool(null);
SetValue("PlayControl.Key", 20, null);
SetValue("PlayControl.Current", 20, null);
SaveKey("cube.kine.local.posx,cube.kine.local.posy,cube.kine.local.posz", 
20, null, null);
SetValue("PlayControl.Key", 40, null);
SetValue("PlayControl.Current", 40, null);
Translate(null, 2.11697550326162, 0, 0, siRelative, siLocal, siObj, 
siXYZ, null, null, null, null, null, null, null, null, null, 0, null);
SaveKey("cube.kine.local.posx,cube.kine.local.posy,cube.kine.local.posz", 
40, null, null);
SetValue("PlayControl.Key", 65, null);
SetValue("PlayControl.Current", 65, null);
Translate(null, -5.05049870063844, 0, 0, siRelative, siLocal, siObj, 
siXYZ, null, null, null, null, null, null, null, null, null, 0, null);
SaveKey("cube.kine.local.posx,cube.kine.local.posy,cube.kine.local.posz", 
65, null, null);
ActivateObjectSelTool(null);
SelectObj("cube1", null, true);
ActivateObjectSelTool(null);
CreateActiveRigidBody("cube1");
SetValue("cube1.RigidBodyProp.statfrict", 1, null);
SetValue("cube1.RigidBodyProp.dynfrict", 1, null);
SetValue("cube.RigidBodyProp.statfrict", 1, null);
SetValue("cube.RigidBodyProp.dynfrict", 1, null);
PlayForwardsFromStart();


We can't boost the static friction above 1. Increasing the Static 
friction scaling in the operator doesn't help. Lowering the the 
simulation accuracy seems to help but introduces jumps.
I'm out of ideas.
