A custom binary format for storing theme information.

This format is still under heavy research!

Channel Modifier

Channel modifiers are used for object models so that objects that face away, towards, or are neutral to the sun are dark, neutral, and lightened respectively. They can also be set for each side of a block as well.

Offset(h)	Size(h)	Type	Description
+0x00	0x04	u32	Red channel
+0x04	0x04	u32	Green channel
+0x08	0x04	u32	Blue channel

Light Index

The light index specify which sides of the block should be neutral, light, or dark, based on what sides face towards or away from the sun:

• 0: Neutral
• 1: Light
• 2: Dark
