MQRC rendering comparison

Movie Quality Render Component (MQRC) renders a lit image through the high-quality path, including temporal accumulation, Lumen updates, exposure, and the final tone-map. For a fair visual comparison, capture BaseCam vget /camera/0/lit png and MQRC vget /camera/0/mqrc/lit png from the same camera transform, resolution, map, and frame after identical warm-up.

The BaseCam path is useful for low-latency observation. MQRC is intended when the image itself matters: temporal anti-aliasing and the complete tone-map preserve highlight roll-off and shadow detail, avoiding the under-exposed look that can occur when a high-dynamic-range result is read without the final post-process.

The comparison above was captured from the packaged Tokyo map at camera location (-5160.632, -1029.995, 138.643) and rotation (0, -1.002, 0). Both sides use camera 0 at 640 x 480 after ten warm-up captures. The MQRC side was returned by scene.capture_view with render_source=mqrc and uses_base_camera_sensor=false.

Recommended sequence:

vset /camera/0/location X Y Z
vset /camera/0/rotation P Y R
vset /mqrc/render_immediately 1
# discard warm-up frames before saving the comparison pair
vget /camera/0/lit png
vget /camera/0/mqrc/lit png
