QuickLook DDS
This package allows OSX Finder to display thumbnails, previews and metadata for "DirectDraw Surface" (DDS) texture files.
Installation
- Download the
.pkgfile of the latest release. - Double-click on it.
- The Installer app will walk you through the installation process.
- To see thumbnails you may need to relaunch Finder (ctrl-⌥-click on the Finder icon in the Dock and choose Relaunch) or log out and back in again.
- You may experience high CPU and disk usage for a few minutes after installation while Spotlight re-indexes all of your DDS files.

Uninstall
- Run the Terminal app (found in Applications → Utilities).

sudo rm -rf "/Library/Application Support/QLdds" "/Library/QuickLook/QLdds.qlgenerator" "/Library/Spotlight/DDS.mdimporter"
- Press Enter.
- Type your password and press Enter.
Limitations
- There's some disagreement on how normal maps are stored. This plugin assumes the DirectX10 BC5 and OpenGL COMPRESSED_RG_RGTC2 convention that R=X,G=Y. Note: this is called "ATI2N (Alternate XY Swizzle)" in some tools.
- There's some disagreement on how the Blue/Z channel in a normal map is reconstructed. This plugin assumes the Blender convention that Blue:[0, 255] maps to Z:[0.0, 1.0]. Note: this is different from the Doom3 convention.
- Palettized and floating point encodings are not supported.
- DirectX 10/11 DXGI encodings other than those listed above are not supported - specifically BC6 / BC7 BPTC encodings.
- Requires OSX 10.6 or later.
