gymapi.AssetOptions().fix_base_link = False -> URDF has gone

[MinW00]

I found all solutions

1. As ‘Abi64’ said if I setting revolute joint in solidworks to URDF then they above subscript ‘*’ mark to effort & velocity.

experienced issue were

• Only base_link part show on the simulation
• Nothing will appear

2. If you have empty <link> part, then it’ll not show on the simulation.
   here is my example urdf file.

3. Must need Inertial part.
   if your urdfs’ inertial values are 0 then, it’ll not appear.
   After I changed inertial values, it shows up correctly
