Getting error: No decoder found for mesh file.

[YashwantMoharil]

Intro

Hi!

I am a graduate student at UMN, I use MuJoCo for my research on Robots and VR.

My setup

I am using Unity 6.2 on windows 11

My question

I am new to unity. I have an xml file which connects to a mesh file. I have downloaded the Mujoco Unity plugin. As I try to import XML file to unity

I get IOException: Error loading the model: Error: no decoder found for mesh file 'C:/Users/yashw/OneDrive/Desktop/nirvana/simulation/mujoco/robot_control/assets/ur5/link0.stl'
Element name 'link0', id 0, line 8

Minimal model and/or code that explain my question

If you encountered the issue in a complex model, please simplify it as much as possible (while still reproducing the issue).

Model:

minimal XML

<mujoco>
  <worldbody>
    <light pos="0 0 1"/>
    <geom type="sphere" size="1" rgba="1 0 0 1"/>
  </worldbody>
</mujoco>

Code:

import mujoco
import mediapy as media
model = mujoco.MjModel.from_xml_string(xml)
data = mujoco.MjData(model)

with mujoco.Renderer(model) as renderer:
  mujoco.mj_forward(model, data)
  renderer.update_scene(data)

  media.show_image(renderer.render())

Confirmations

• I searched the latest documentation thoroughly before posting.
