Model sets use 2K texture maps; tiling surfaces use 4K maps. GL normal maps are used without inversion. Packed ARM channels are AO=R, roughness=G, metallic=B; standalone roughness uses R. Albedo is color data, normal/roughness/ARM are linear data. Texture imports use mipmaps and VRAM compression. Each model surface has its own external StandardMaterial3D resource and keeps its original UVs. Runtime model.scn resources reference those materials. Surface sets have external surface.tres resources.

Rebuild using scripts/prepare_quarry_realism.gd after importing the source glTF and textures. Download scripts are under tools/art. Runtime integration is confined to QuarryRealism and Quarry's terrain modules. No runtime network downloads.
