Reduce the red, green, and blue intensities by half, resulting in a dimmer, darker ambient light while maintaining the same neutral grayish-white color.
vVrsion using a quaternion orientation. This defines a fixed orientation looking roughly toward the center of the tray, assuming a diagonal tilt (approximate iso-style view).
MuJoCo XML schema does not support a shadows attribute under <quality>. That attribute might have existed in older MuJoCo forks or be a confusion with <lighting> blocks in other simulation engines.
10 dynamic objects (mixed boxes and spheres, with bright colors). A light grey tray with side walls. A black disc pusher. Bright skybox background. A top-down tilted camera. Offscreen rendering resolution set to 640×640.
MuJoCo XML parser does not understand Jinja-style templating (i.e. {% for ... %} or {{ ... }}), so you must replace that block with explicit, valid XML.
