Rendered output looks like this:

templateScene appears to be broken.
This issue did not occur in earlier versions.

nightscene.json

{
  "emittersEnabled": true,
  "emitterIntensity":15,
  "sunEnabled":false,
  "fastFog": false,
  "transparentSky":false,
  "emitterSamplingStrategy": "ONE",
  "fogDensity":0.0,
}

Some sections appear as if they're only partially rendered, as if the rendering process stops midway.

I’m experiencing the same issue: the rendering is incomplete, with black squares and visual noise, but no logs are being generated.
