incorrect rendering effect when using simbody physics engine #2464

Open osrf-migration opened 6 years ago

osrf-migration commented 6 years ago

Original report (archived issue) by Jack Liu (Bitbucket: jacknlliu).

I got incorrect rendering behaviour when using simbody physics engine.

gazebo -e simbody  test.world

And using ODE and DART, we can get correct rendering effect.

gazebo  -e ode test.world

The test.world is
