Constraints are too strong in HL2 maps

[birkett]

Testing with HL2 Single Player, the turnstile on d1_trainstation_01 cannot be walked through, Also, cans cannot be picked up.

I propose using the HL2 SP campaign as a feature test against Havok.

Yep! I've been playing through the HL2 campaign levels as a test, but gmod loves to crash because it keeps running out of memory. There's an old issue for it in the gmod repository: Facepunch/garrysmod-issues#460
EDIT: Nevermind, out of memory issue was on my end, I had a debug feature enabled that bloated memory allocations.

The turnstile is part of a bigger issue with the bullet constraints: IVP constraints aren't as rigid and tolerate error, but bullet constraints have the tendency to freak the fuck out. I'll have to see what I can do about that.

And I have no idea what's wrong with picking up cans and other objects, it looks like you can move them around but they just don't rise vertically. Will look into it.

+use pickup doesn't appear to be picking up some objects because a contact constraint is keeping them on the ground. The game does request a target position above the ground in ComputeShadowControl.

Okay, yeah that's fixed. Now why does it damp angular rotations by a factor of 10 when the object is picked up?

+use stuff was fixed in 49f99b6. Need to address constraint strength.
