I'm getting the following errors using a simple sdf file that I get from the tutorial of animating a box:
[ruby $(which gz) sim-1] [GUI] [Err] [MeshManager.cc:131] Invalid mesh filename extension[tutorial/worlds/__default__]
[ruby $(which gz) sim-1] [GUI] [Err] [SceneManager.cc:1027] Actor skin mesh [tutorial/worlds/__default__] not found.
I tried adding armature to the box in blender but with no success.
I'm using Gazebo garden on ubuntu 22.04.
It seems not possible to use collada object in modern gazebo, unless if it has a mesh with skeletal animation. instead you can use trajectory follower.
