<!-- CHANGE: body pos="" deleted for all bodies (you can also set pos="0 0 0", it works)
|
|
Interpretation of body pos="" depends on coordinate="global" above.
|
|
Bullet doesn't support global coordinates in bodies, little motivation to fix this, as long as it works without pos="" as well.
|
|
After this change, Hopper still loads and works in MuJoCo simulator.
