It seems that I’m missing some kind of a plugin? The docs don’t mention anything about it

Hi @Ulfrend,

We don’t currently support loading assets from USD, apologies for the confusion of USD mentions from the documentation. We will make sure to remove them for future releases. Asset types supported are MJCF and URDF. Our latest release also supports importing meshes (referenced from MJCF or URDF assets) in any format that Assimp supports.
