Generated meadow albedo
meadow-albedo-generated.png is a synthetic photographic-style texture generated for this project using the image-generation tool and copied into the vegetation package. It is not a photograph, scan, or user-supplied image. The runtime uses this project-local copy only; it does not access the generation tool or its cache.

GROUND_TEXTURES.grassfrom the vegetation package.
In the current landscape, a useful starting point is albedoBlend: .55 and albedoScale: {grass: .35}. These are visually tuned settings, not measured physical properties of a photographed surface. Full-strength and procedural-only versions were compared at identical camera and frozen lighting. The restrained blend retains the procedural broad variation while adding finer dry grass/thatch detail.
The material keeps its procedural height/normal detail. This file supplies color only; it has no corresponding measured normal or height map. It is optional and does not by itself make the terrain photorealistic.
Direct comparison and cost
The existing vegetation fixture rendered the real 8 km terrain and 24,000-tree forest in Chrome. At the same frozen ground-level camera, blend .55 and grass scale .35 added visible dry grass/thatch detail while retaining the existing broad terrain variation. Full strength at scale 1 appeared excessively fine and carpet-like in that view, so that combination was not selected. Woodland views were also compared visually. No shader errors or warnings were observed.
The measured ground view used high quality, a 1835 × 1010 CSS canvas, a 2293 × 1262 drawing buffer, 101 near and 1,216 middle tree instances, 47 draw calls, and 7,714,934 submitted scene triangles. Forty sampled frames per setting produced the following medians:
| Setting | Frame CPU | GPU | Forest update |
|---|---|---|---|
Procedural color (albedoBlend: 0) | 3.10 ms | 43.00 ms | 0 ms at timer precision |
Generated color (.55, grass scale .35) | 3.70 ms | 45.57 ms | 0 ms at timer precision |
Camera, frozen time, draw calls, and triangle counts were unchanged. The observed GPU difference was +2.57 ms in this unusually dense close view. This is a single-view local comparison, not a general performance guarantee or an assembled-flight measurement. The procedural baseline retained the optional sampler configuration with its uniform blend set to zero; the image was already loaded for both samples. Asset decoding and initial GPU upload were not timed. The engine's no-asset default compiles the authored sampler paths out entirely.
The focused ownership/readiness suite passed all eight reported tests, including cancellation during fetch and late decode. The actual PNG decoded through native createImageBitmap and rendered successfully. Machine-readable settings and evidence are in ground-albedo-albedo2.json.
