SubblockMode

A optional mode for regular sub-blocks.

Values

Octree

Sub-blocks form a octree-like inside the parent block.

To form this structure, cut the parent block in half in all directions to create eight child blocks. Repeat that cut for some or all of those children, and continue doing that until the limit on sub-block count is reached or until the sub-blocks accurately model the inputs.

The sub-block count must be a power of two in each direction. This isn't strictly an octree because the sub-block count doesn't have to be the same in all directions. For example you can have count (16, 16, 2) and blocks will stop dividing the the W direction after the first split.

Full

Parent blocks are fully divided or not divided at all.

Applications reading this mode may choose to merge sub-blocks with matching attributes to reduce the overall number of them.
