People use it for CGI, animations, and plenty more cool stuff. As Leland Brown has put it, this looks sort of like wrinkled tinfoil full of sharp edges.īlender, on the other hand, is designed specifically for 3D modeling. This standard GIS hillshade looks OK, but it’s rather noisy and harsh. All of these programs use basically the same algorithm, and you get a pretty similar results, as seen below.
Most of the cartographers I know do their shaded relief in ArcMap or another GIS program, or sometimes they use Photoshop or Natural Scene Designer. Why Blender? In short: Blender makes better-looking relief. Version 1.0 (Nov 16, 2017) - Initial release of text version. Both of these tips are courtesy of Dunstan Orchard. Version 1.1 (Jan 29, 2018) - Changes to Chapter 6: Added section on denoising, and alterered render settings to suggest using Limited Global Illumination. Version 1.2 (May 14, 2018) - Added new section in Chapter 7, pointing readers toward the idea of rendering relief on a pre-colored plane. Thanks to Diane Fritz for her notes on changes, which helped me double-check my work. Removed some no-longer-needed material, such as UV unwrapping, are no longer needed.
Many steps rewritten to reflect new interface elements and new names for tools/features/menu items. All screenshots replaced to reflect the new UI.
Version 2.0 (Sep 29, 2019) - Major revision for Blender 2.80. Version 2.1 (Oct 30, 2019) - Added step in Chapter 6 to change the heightmap’s color space, to avoid lowlands being washed out. Denoising is now default, so I adjusted that section and removed a good chunk of it. Discussed render performance earlier (as it bogged down for me earlier in the process). Version 2.3 (Jan 13, 2022) - Edits to the last page, including a link to a discussion of how to make Blender relief look less Blender-y, and an updated oblique map.
