A movable timber board for pinning references. Quality-pass revision with procedural texture maps, derived normals and packed roughness.

Drag to orbit after opening. The model starts stationary.

For your engine. The download is a standard glTF 2.0 binary (GLB) with PBR metallic-roughness materials. glTF stores materials, not lighting or tone mapping, so your engine decides how they read. This 3D view tone-maps with Review Neutral, the Khronos PBR Neutral construction with a smaller glare offset (0.015 instead of 0.04), at exposure 0.9. Its Tone mapping control also shows ACES and Linear, for comparison.
