This is a similar question to http://answers.gazebosim.org/question/22437/the-question-is-regarding-collada-dae-file/
I have a 3d model of a plant 
When I export it as a .dae from Blender it exports the file into multi parts
When I add the plant to my URDF file:
>>> >
It shows up grey in simulation and in RVIZ:
Is there a tutorial on how to export a model from blender and get the textures to show up in gazebo?
When I try to export it as a .obj from Blender I get two files .mtl and .obj but not sure how to load them or where the textures are. The obj looks like a different approach. How are these images made and exported https://github.com/osrf/car_demo/blob/master/car_demo/models/mcity/materials/textures/RailroadGate.png
Thanks in advance,
Matt
