Gazebo’s mesh loading library doesn’t support glTF2 and FBX mesh loaders. There are two ways to extend the capabilities of the Gazebo’s mesh loading system, (A) Using an external open-source library or (B) Writing glTF2 and FBX mesh loaders consistent with the current approach.

An initial analysis is required to decide which approach is better. I am planning to generate such analysis in the next couple of days, so any idea is welcome. The main aspect of the analysis will be around:

1. Maturity analysis  
Which file types are supported by the external library, development history of the external library.
2. Complexity analysis  
Complexity comparison of possible external libraries and developing new glTF2 and FBX mesh loaders similar to existing approach.
3. Testing difficulty analysis  
Testing difficulty comparison of the possible external libraries versus the existing approach.
4. Required time to Implement vs Integrate
