SRD (Or Spike Reference Descriptor as it is theorised to stand for) is a file format that stores information about an object, typically models. Each entry in the file has a different piece of information about the end product.

SRD "archives" themselves are very simple; they're simply a collection of SRD entries, one after another.

SRD entries all follow a simple pattern; a 4 byte string (although it could be read as a number) for the data type. This is followed by a 4 byte Big Endian int for the data length, then a 4 byte BE int for the subdata length, then a 4 byte padding number.

Alignment

All "blocks" in a SRD file and entry are aligned to 16 bytes. This means, if a entry is only 10 bytes, there will be 6 bytes of padding. If the entry is 125 bytes, then there will be 3 bytes of padding. Both the main data block and subdata block are subjected to this padding.

Entry Types

TXI (Texture Information)

This entry contains information about textures, put bluntly.
