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

I found all solutions 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 [image] If you have empty <link> part, then it’ll not show on the simulation. here is my example urdf file. [ex] Must need Inertial part. if your urdfs’ inertial values are 0 then, it’ll not appear. After I changed inertial values, it shows up correct…

I’ve got same problem before.
Most of them are URDF problems

check out requirements in your joint part
ex) revolute → velocity & effort etc …
