3.3

Status: Released

The 3.3 release improves image quality for normal maps, and two component textures. Normal maps are expected to compress 25% slower than the 3.2 release, although it should be noted that they are still faster to compress in 3.3 than when using the 2.5 series. This release also fixes one reported stability issue.

• General:
  • Feature: Normal map image quality has been improved.
  • Feature: Two component image quality has been improved, provided that unused components are correctly zero-weighted using e.g. -cw on the command line.
  • Bug-fix: Improved stability when trying to compress complex blocks that could not beat even the starting quality threshold. These will now always compress in to constant color blocks.
