cc @scpeters in case you have opinions on these APIs. There are some merge conflicts that need to be resolved otherwise looks good to me.

I just tested this on harmonic and I get the same issue. Also tried loading the default ~/.gz/sim/9/gui.config and gives me the same gray 3D scene.

with https://github.com/gazebosim/gz-sim/pull/2270, we can now set the max no. of contact points for all collision pairs in SDF. For dartsim, it comes down to the [SetWorldCollisionPairMaxContacts](https://github.com/gazebosim/gz-physics/blob/707aa699c196caa6eb384c74ea75ed3a382c5129/dartsim/src/WorldFeatures.cc#L101-L120) function in gz-physics. However,...

nice! would you like to create a pull request for this?

> does it work to set required="-1" in the include element? oh I didn't know about this! Just found what -1 means [in the parser code](https://github.com/gazebosim/sdformat/blob/fc84f94d147bf31fd594e17bade68946246236b3/src/parser.cc#L1640-L1641). I think that's what...

> do we have support for stereo-cameras yet in gz-sim? Gazebo-classic uses a `multicamera` sensor so that it can guarantee the cameras are synchronized / updated in the same timestep....

I originally thought `//camera/pose` is used for rotating the camera to optical frame but no you're right it's for `multicamera` sensors. If there are other consumers of sdformat (other than...

Closing this. The new Gazebo will not use this SDF element but there maybe users out there who do need `multicamera` + `//camera/pose` .
