Heightmaps aren't loading in Gazebo7

I'm running Gazebo7 and can't seem to get any model files (or world files) with to load. It will sometimes cause Gazebo to crash unexpectedly. Are heightmaps still supported with Gazebo7? If so, what am I missing? The default heightmap.world and the apollo landing site and my custom heightmap model are all not loading. Other custom models have not problem loading. Do I need to use DEMs instead of heightmaps?

How are you trying to load the heightmaps? Are you opening a world which has them or inserting them from the insert tab?

Both cause failures on my machine. Running from the command line with a .world file containing a heightmap attribute or inserting a model from the GUI's "insert" tab.

I am able to load worlds containing heightmaps using Gazebo7 on my machine. What's your OS and how did you install Gazebo? Do you see any errors printed if you run gazebo --verbose?

I am running Ubuntu 16.04 currently. The problem was first noted on Ubuntu 14.04 a few weeks ago. I upgraded to Ubuntu 16.04 and reinstalled Gazebo7 via the curl command on the installation page. The --verbose error when I click on those models to import include:
[Err] [Visual.cc:2739] No mesh specified I'm a little concerned I changed around a gazebo resource path in that case since the default Apollo Landing site model gives this error in addition to my custom models.

I am running Ubuntu 16.04. Problem first appeared on 14.04. I upgraded to 16.04 and reinstalled Gazebo7 using the curl command on the tutorial. Running with the --verbose command gives the error [Err] [Visual.cc:2739] No mesh specified This is concerning to me since the default Apollo Landing site model gives this error. Hopefully I didn't mess up a gazebo resource path somewhere.
