Dynamic object resets to old position:

- make a dynamic cube

- playback and Esc

- rotate/move the cube a bit

- playback again

- cube switches to the old position/orientation


Duplicated objects do not carry their physics properties

Margin around objects with convex hull collision type

There is a somewhat large margin around objects with convex hull collision type.

- add a cube with shape set to convex hull - simulate the cube falling onto a plane set to passive. You will see it doesn't actually touch the plane, and there is a fairly large margin when compared to setting the cubes shape type to box.

Working correctly in latest build r31177


Blender crashes when removing a rigid body object and pressing play

- add a cube

- add cube to rigid body

- remove cube from rigid body

- press play

video demo: http://auralgrey.com/storage/blender/remove_add_crash.mov

  • this also occurs if you just delete the rigid body object and press play
    • this also occurs if you remove a rigid body from an object then add it back to the object and press play

Fixed in SVN (Aligorith)


Mesh shape does not conform to the shape of the mesh

- add a cube, and a plane

- place the cube above the plane

- set the cube to active rigid body, add the plane to passive

- on the cube change collision shape to mesh

- rotate cube so that is will land on a corner

- press play and see that the lands as if it were just in a bounding box

video demo: http://auralgrey.com/storage/blender/meshshape_not_working.mov

  • changing the collision type to box or convex hull will show the correct result

No discernable change when adjusting margin or bounciness or friction settings

- create a basic cube falling on to a plane setup.

- changing margin, friction, or bounciness on the cube, plane or both does not seem to show any change in the simulation

Working in latest builds r31177


Blender crashes when using undo/redo to remove/add a rigid body to object

- add a cube

- add rigid body to cube

- undo

- redo

- undo again, results in crash
