How to reverse the control of camera zoom using the mouse wheel?

[GF-Huang]

Intro

Currently, scrolling the mouse wheel upward zooms the camera out (away from an object). I’d like to reverse this behavior—how can I do that?

My setup

Windows 11 25H2

mujoco                    3.6.0
mujoco-mjx                3.6.0

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())
