Any chance we could SDK support for set/get userData for NewtonCollision objects .... similar to the NewtonCollisionGetUserID. Looks like functions are there in dgCollision but they're not exposed in the SDK.

the collsion are reused,
for example two cubes with the same size and matrix, will be the same pointer with a increaded ref count, so the concept of user data does not work on shared resource.
you can do this, you can make each shape unique, by calling NewtonCollisionMakeUnique afte you create a collision,
thsi will remove form the cache and then you can write your use data as as a pointed save on the ID.
GetUserData on the collision is a legacy funtion that is no use anymore.
