Objects pushing through Empty Objects pushing through

I'm having that problem with objects falling too fast and pushing through walls. I've tried the FPS tweak but I'm still having that. The scene is quite simple with no more than a hundred or two of triangles but after loading objects, they move too fast for a while until physics syncing.

I just want to know if there's another solution. I'm using 1.3.1, by the way.

Cheers

Maybe increase the collision margin, simply add a user property to the objects named "margin" type float.

I had similar issues. My scene is very simple so I was able to step the simulation twice per frame instead of two, which seems to have stopped things from pushing through. Playing with the scale or margin didn't help for me.

When I was looking at this I came across something in the bullet code that said if you only step once per frame (which I think is the default), you have to update at fixed time intervals. That might be worth a try if you can't afford an extra sub sample.

BTW, I'm using 1.3.1.

True, another good way to prevent that is to increase the simulation step:

Code:


      sio2PhysicRender( sio2->_SIO2physic,
                sio2->_SIO2window->d_time, 2 );

Setting simulation step to 2 solved the problem.

Thanks!

Cheers.
