Collada loading errors with drcsim prerelease from .debs

With current drcsim prerelease from .debs installed, the following gets spammed (at least for me) when Gazebo comes up:

#!

[Err] [ColladaLoader.cc:1670] Collada file[/opt/ros/indigo/share/drcsim_model_resources/gazebo_models/environments/atlas_description/meshes_unplugged/r_clav.dae] is invalid. Loading what we can...

While this wouldn't be expected from above output, the robot model gets spawned just fine in Gazebo. I noticed that the .dae files for most (but not all) Atlas links fail to load on ROS hydro rviz, however. That's another hint that something about them seems to be incompatible with the standard (?).

I don't know why rviz would be having trouble, but there is a fix for the warning messages in gazebo, as @iche033 said.

Ok, sounds good. Not sure about the rviz trouble (it obviously also works in indigo rviz). I think this can be closed then.

For reference in case of future woes with the collada files I´m adding some info about what happens with rviz hydro:

atlas_v4 in rviz hydro:

atlas_v5 in rviz hydro:

As can be seen, for some reason a few collada files get loaded, while others don´t. Interestingly, the same links are affected, even though different models are used. Terminal output:

#!

We are seeing this issue in Hydro; we would much prefer to stay on Hydro until the DRC Finals if possible.

It might be worth to take a look at the COLLADA files for the l_uleg/r_uleg (i.e. thigh) geometries as the right one curiously shows up, while the left one doesn't do so. Even on Indigo, they're a shaded a little bit differently, suggesting that even there some (likely unintended) difference exists.
