To do: Cleanup.
The entire MOD file documentation is currently being hosted online on a public MEGA folder containing a lot of information on the Pikmin 1 file formats.
Here is the document details:
MOD files practice 0x20 alignment for chunks and often sub-sections. All Chunk Types ['0x00', '0x10', '0x11', '0x18', '0x20', '0x22', '0x30', '0x40', '0x50', '0x60', '0x100', '0x110', '0xffff', '0x41', '0x13', '0x19', '0x1a', '0x61', '0x12'] Ambrosia speculates that... Chunk 0x0013 is vertex colors Chunk 0x0019 has shadows?

If multiple bytes are toggled, the Least Significant Bit is considered. Inverted Semi-Transparent is an exception to this rule. For it to be active, at least one of the other states must be active at the same time. It itself does not get modified by other states.

Also, "mud" sounds like sand. The "water" attribute is what causes Pikmin to drown. Calculating the Magnitude 1) Solve for the center of the tri (average the three XYZ positions) 2) If necessary, recalculate the face's normal with a cross factor 3) magnitude = (avg_x * norm_x) + (avg_y * norm_y) + (avg_z * norm_z)
