XML Error: unknown plugin 'mujoco.elasticity.cable' when running simulate #723

How did you obtain/install MuJoCo on your machine? |
I downloaded source code from github of MuJoCo, and built it using cmake. (make build;cd build;cmake ..;make -j 8) Under bin, run "simulate" and drag "belt.xml" to it. |

@saran-t Thank you for your help. It works. I suggest this information of searching for plugin directory should be added to the "build from source" section. |
@JohnChen1024a, would you like to submit a PR to update the docs as you propose? |

@DMackRus the plugins are actually built when you run This is an oversight in our installation setup, but in the meantime you should be able to find these plugins in the |
Thank you for your reply, yes that makes sense and I can just add a quick command to my shell script to copy the plugins folder over then to automate my issue, thanks! |
When I loaded the model "belt.xml" in the directory of model/plugin to "simulate" program of MuJoCo, I got the following error message:
XML Error: unknown plugin 'mujoco.elasticity.cable'
Element 'required', line 20
