cannot load file in GAZEBO_RESOURCE_PATH
Hi, I'm trying to create an outdoor world using a mesh file that I downloaded from Google SketchUp library and then exported to DAE using Google Sketchup. I am getting this error:
Error [SystemPaths.cc:262] cannot load file [mountain.dae]in GAZEBO_RESOURCE_PATH[/home/sameer/ros/falkor_quadrotor/falkor_quadrotor_gazebo/worlds:/opt/ros/fuerte/stacks/simulator_gazebo/gazebo_worlds:/opt/ros/fuerte/stacks/simulator_gazebo/gazebo/gazebo/share/gazebo]
Error [MeshManager.cc:150] Unable to find file[mountain.dae]
Segmentation fault (core dumped)
the file mountain.dae is in /home/sameer/ros/falkor_quadrotor_gazebo/worlds
I'm loading it in with my world file like this:
<model name="ground_model" static="true">
<link name="ground_link">
<origin pose="0 0 0 0 0 0"/>
<collision name="ground_collision">
<geometry>
<mesh filename="mountain.dae" />
</geometry>
I've tried using package://falkor_quadrotor_gazebo/worlds/mountain.dae as the filename as well but that also gave me an unable to find/core dump error.
I have since hardcoded the pathname and now I'm getting this error:
Error [ColladaLoader.cc:66] Unable to load collada file[/home/sameer/ros/falkor_quadrotor_gazebo/Media/models/mountain.dae]
Error [ColladaLoader.cc:70] Missing COLLADA tag
As noted earlier, I saved this file using SketchUp. I looked at the file and there is a COLLADA tag right there in the beginning:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<COLLADA xmlns="http://www.collada.org/2005/11/COLLADASchema" version="1.4.1">

Thanks.
I remember having the same trouble... I want to say it had to do with the <export><gazebo gazebo _ media _ path=${prefix}"/></export> line in the manifest.xml file, but it has been too long now. I also still have trouble with plug-in paths and find myself just hard coding the path into my files.
I actually hardcoded it (well I used $(find package)) and that didn't work either. I also tried package://etc/filepath I think.. Will try some other ideas.
Only ROS uses the "package://" URI. Gazebo uses either "file://full-path-to-mesh" or "model://name-of-model-in-modeldatabase/meshes/my-model-file.dae"
