This page pertains to the format of the Texture Subfile within the Savegame files. This file has Type ID c97f987c. This particular subfile was decoded by smf_16.
Description
This subfile contains data about the textures in the city. For every lot in the city 1 texture record exists. Within every texture record is a list of all textures used on the lot, both base and overlay textures.
Structure
The Texture subfile has the following format:
DWORD Size DWORD CRC DWORD Memory WORD Major version (0x0002) WORD Minor version (0x0004) BYTE Unknown, only seen 0x00 BYTE Unknown, only seen 0x00 BYTE Unknown, only seen 0x00 BYTE Unknown, mostly 0x05, probably an appearance flag. (A) DWORD Unknown, always 0x497f6d9d BYTE Min Tract X (normally between 0x40 and 0x7f) BYTE Min Tract Z (normally between 0x40 and 0x7f) BYTE Max Tract X (normally between 0x40 and 0x7f) BYTE Max Tract X (normally between 0x40 and 0x7f) WORD X Tract Size? (only seen 0x0002, probably indicating the size is 2²) WORD Z Tract Size? (only seen 0x0002, probably indicating the size is 2²) DWORD Unknown, only seen 0x00000000 DWORD Unknown, only seen 0x00000000 DWORD Unknown, only seen 0x00000000 DWORD Unknown, only seen 0x00000000 FLOAT32 Min X Coordinate FLOAT32 Min Y Coordinate FLOAT32 Min Z Coordinate FLOAT32 Max X Coordinate FLOAT32 Max Y Coordinate FLOAT32 Max Z Coordinate BYTE Unknown, seen 0x01 and 0x02 DWORD Count of tiles with a texture DWORD Instance ID of the texture BYTE X tile BYTE Z tile BYTE Orientation BYTE Priority 0x00 for base texture, 0x01 for overlay texture 4 BYTES Unknown, mostly 0xff, seen several other values as well BYTE Unknown, mostly 0xff but seen 0x03 and 0x01 as well BYTE Texture variation, see below
Texture variation
The texture variation byte indicates what texture variant of the texture family the game was using when it created the Savegame. Setting this value does not seem to have any influence as the game randomly picks a texture variant from the family when opening up a city, and even when saving a city.
Remarks
Byte (A) is probably an appearance flag in the same way an appearance flag is used in the Prop Subfile. It is mostly set to 0x05, or 0b00000101.
