Packfile

Packfiles are memory image. Due to the nature of native memory format, requires conversion before such as 64-bit import is not currently supported due to SDK's limitation at the moment.

Save in this format is strongly not recommended.

Usage

Export options

• Scale
• Compression
  • Uncompressed - Best quality
  • Quantized Compression - Faster decompression
  • Spline Compression - Smaller size
• Compression Level
• Autobake

Autobake

Unlike animation software support interpolations with bezier splines, all animation files used in game engine must be baked (keyframed on each frame) before use. For example, export animation like image above won't play correctly in the engine. If this option is enabled, the CKExporter automatically bake keyframes on export.

This option is also useful to make animation file like single pose.

Hint

• Wavelet compression and Delta compression are deprecated and export in such compression is not supported. HKA-1340
• Higher compression level introduce more artifacts like foot sliding. Use higher compression level is not recommended or do not compress if animation has subtle moves like idle animations.
