Generating True Mesh Displacement and Grayscale Bump Maps from 2D Images

Whether rendering close-up architectural stonework in Cycles/Octane or adding subtle surface grain to a real-time shader, artists need clean elevation data derived from 2D textures. Pairing true 3D mesh displacement map synthesis with high-frequency grayscale bump map extraction lets you separate macro silhouette depth from micro-surface texture.

Displacement vs. Bump in 3D Rendering

Macro Silhouette Geometry vs. Fine Shader Detail

• Displacement Maps: Drive actual vertex elevation on subdivided meshes so brick silhouettes and rock ledges cast real geometric shadows.
• Bump Maps: Capture fine pores, scratches, and weave patterns for fast shader evaluation without adding polygon count.

3-Step Elevation Workflow

1. Drop your 2D surface image into the displacement or bump workspace.
2. Tune macro depth and fine detail sliders under rotating directional light.
3. Download the lossless grayscale PNG maps for your 3D renderer.
