How to render depth map 3D models for artists?

Artists render depth map 3D models by using 3D software (like Blender or Maya) to generate a grayscale depth pass—lighter pixels represent closer objects, darker ones farther away. Depth maps add realistic effects (e.g., parallax, depth of field, occlusion) to projects such as game assets, digital paintings, or video compositing. For beginners, start with Blender’s Compositor: enable the "Depth" pass, export the map, then use it in Photoshop to create a layered parallax effect for 2D art. This simple workflow lets you test how depth maps boost visual depth without complex setups.
