$animblocksize

$animblocksize is a QC command available in all Source games. It changes how animation data is stored within the model.

Normally, all animation data is stored in the .mdl file. If this is specified, all the animation data will instead be written to a .ani file, and when sequences are needed, the data will be loaded on demand. This is helpful for streaming animation data of baked physics. The "size in K" is the block size the animations will be grouped into. Sizes between 4K and 64K are fine, though 16K or 32K has better memory fragmentation characteristics.

Bug:In games with support for compressed (repacked) maps, the client will crash when attempting to load on-demand animation data if the content is packed into the BSP.  [todo tested in?]

Syntax

$animblocksize	(size in K) [nostall] [highres] [lowres] [numframes] [cachehighres] [posdelta <float>]

The optional commands are:

nostall

If the animation is splitted into sections the first section is saved in the .mdl file. This usually prevents a model from stalling when loaded mid-game, if it has particularly complex animations that otherwise might take some time to load.

highres (in all games since )

Animations are stored as frames if lowres is not specified.

This disables low resolution animations.

This makes position animation frames be stored as uncompressed vectors else the are compressed.

lowres (in all games since )

This disables high resolution animations.

This makes animations data be compressed and not stored as frames.

numframes (in all games since )

cachehighres (in all games since )
