pymjcf: assets dict is too big

[umeiko]

I decomposed my model into many pieces of convexhall meshes (about 2k), then tried to load it into pymjcf, with API mjcf.Physics.from_mjcf_model, it raised a ValueError: assets dict is too big. whether load them with .xml or python's for loop will trigger that Error. But load them with mujoco.Physics.from_xml_string goes all right. I don't know if this is a bug in pymjcf or it has some way to avoid. I really loves pymjcf to build my envirment. IssuesExample.zip

My Envirment

• Windows 10
• Python 3.8.13 (default, Mar 28 2022, 06:59:08) [MSC v.1916 64 bit (AMD64)]
• dm-control 1.0.10
• mujoco 2.3.2 Here attached codes that can correctly import same files of convexhall meshes by mujoco.Physics.from_xml_string. I can't understand why same .xml model which works via mujoco.Physics.from_xml_string but not works via mjcf.Physics.from_xml_string. IssuesExample.zip
