Active D2 Range: Frames 1100-3988 (96.27 seconds of title screen)

Snow Layer Structure

Property Value Confidence Source
Layer count 1 primary layer HIGH Optical flow + contour analysis
Layer type 2D billboard HIGH No z-depth parallax at 30fps
Spawn Y range Rows 30-120 HIGH Particle distribution analysis
Particle size 1-30 px² HIGH Connected-component filtering

Particle Distribution

Strip (rows) Mean V Particle Count
0-15 69.4 0
15-30 85.9 0
30-45 84.3 0
45-60 123.8 3
60-75 118.3 4
75-90 94.5 0
90-105 125.3 4
105-120 131.9 6

Total visible particles: 8-15 at any time (mean ~8-12)
Bright-pixel count (V>200): ~2,000-2,300 px per active frame

Snow Drift

Metric Value Confidence Notes
Drift speed X <0.01 px/frame MEDIUM Below 30fps resolution
Drift speed Y <0.01 px/frame MEDIUM Below 30fps resolution
Estimated speed <0.3 px/s LOW At 30fps, true speed may be higher
Drift direction None consistent HIGH No directional bias observed

Interpretation: Snow particles are either static or moving so slowly that motion falls below detection threshold at 30fps. At 60fps capture (or on actual RG hardware), particle motion may be visible.

Background Behavior

Property Value Confidence
Color Dark gray/blue-gray (B≈77.5, G≈74.5, R≈65.2) HIGH
Pulsing None observed HIGH
Color cycling None observed HIGH
Stability Stable across all frames HIGH
