unrecognized attribute passive

[jahneric]

Intro

Hi!

I am a undergrad student at Scads.Ai Leipzig I use MuJoCo for my research on biomechanical simulations . When try to import two mujoco scenes ( (MoBL-ARMS Dynamic Upper Limb from opensim and a task xml where there is just a button and a screen) ) in unity and try to run a script on it based on captured qpos values, it always says:

IOException: Error loading the model: XML Error: Schema violation: unrecognized attribute: 'passive'
Element 'flag', line 1

I already tried to delete the line from the parsed xml )and also tried to change the script of MjScene so it ignores any line with passive in it.

My setup

Mujoco 3.3.6, Unity Plugin 3.3.6, Unity 2022.3.62f1

My question

What could i consider to change? is there anything special with importing mujoco scenes?

Minimal model and/or code that explain my question

No response

Hello! Thanks for reporting this. A fix for this is coming in the next release. Right now you can either downgrade to 3.3.5 or you can use this branch with 3.3.6:
