Parity with LU Toolbox's Process Model, Bake Lighting and icon renderer, with its defaults as the settings' defaults: - Colors from its LU palette (UgcPalette: LU colors, LDD colors mapped to the nearest LU one, unknown ones black), transparent bricks at 58.82% opacity, a brick transparent only when all of its materials are. - Color variation: each brick's material gets its HSV value shifted in a 2.224 gamma by up to 5% (times the color's own amount), from a random number of the model, brick and material, so reprocessing gives the same colors in every LOD. Icons get none, and the icon renderer's color corrections. - LODs 0 and 2 with its distance logic, written as NiLODNode/NiRangeLODData like its exports and the game's own brick models, shapes divided at 65535 vertices along the longest side like divide_mesh. - Ambient occlusion like its AO-only bake: 64 rays per vertex, distance 5, after hidden surface removal, transparent bricks neither baked nor occluding, glow colors added. - Icons from its icon scene: 50 mm lens at 53.4/19.5 degrees, sun of 2.5 at 21/50.3 degrees with soft shadows, grey world light with occlusion; LOD 0's hidden surface removal and occlusion are reused for them. - Optional ground plane for hidden surface removal; stats.json per model and the previous version's previews kept for comparing. Budgets, applied live on config reload: max_cpu_percent (workers account their thread CPU time and sleep to stay under it, long renders included), worker_nice, max_memory_mb (jobs are estimated from their brick count and wait until they fit), max_model_bricks and pause_hours. /status and the traffic report show CPU, memory and throttling.
