Revision as of 16:54, 26 November 2017

See TXTR (File Format) for the other revisions of this format.

The TXTR format is Tropical Freeze's texture format. The image data in the GPU buffer is compressed using LZSS compression.


This file format needs a lot of research
Most everything in the header + image compression formats needs to be cracked + documented.


Format

The format starts with the typical form descriptor found in every Tropical Freeze format. Following that, there's a HEAD header section that contains most of the texture parameters, then the GPU section containing the actual compressed image data. This is the structure of the HEAD section:

Offset Type Count Name Notes
0x0 Chunk Descriptor 1 HEAD Chunk Descriptor
0x18 u32 1 Texture Type
0x1C u32 1 Texture Format
0x20 u32 1 Width
0x24 u32 1 Height
0x28 u32 1 Depth
0x2C u32 1 Unknown
0x30 u32 1 Swizzle
0x34 u32 1 Mipmap Count
0x38 u32 Mipmap Count Unknown array Appears to be mipmap sizes, but it doesn't match the size of the image data (unless there's 1)...
u32 1 Unknown This parameter is part of NTextureFormat::STextureSamplerData (along with the next 4 parameters)
u8 1 Texture Filter
u8 1 Texture Wraps X
u8 1 Texture Wrap Y
u8 1 Texture Wrap Z

Texture Type

This enum basically maps directly to a GX2SurfaceDim enum.

ID GX2SurfaceType

4 GX2_SURFACE_DIM_1D_ARRAY
5 GX2_SURFACE_DIM_2D_ARRAY
6 GX2_SURFACE_DIM_2D_MSAA

Texture Filter

Invalid values default to 1 (linear).

Texture Wrap

Invalid values default to 0 (clamp).

PAK Metadata

The pak metadata for the TXTR format primarily contains compression-related information and provides the values required to decompress it.

Offset Type Count Name Notes
0x0 u32 1 Unknown
0x4 u32 1 Unknown
0x8 u32 1 GPU Section Offset Relative to the start of the file
0xC u32 1 Unknown
0x10 u32 1 GPU Data Start This is the offset to the start of the GPU data, immediately after the GPU section header.
0x14 u32 1 GPU Section Size Matches the size from the GPU section header.
0x18 u32 1 Compressed Buffer Count
0x1C Compressed Buffer Compressed Buffer Count Compressed Buffer Array

Compressed Buffer

This is a small struct that defines a compressed data buffer within the GPU section.

Offset Type Name Notes
0x0 u32 Decompressed Size
0x4 u32 Compressed Size
0x8 u32 Offset Relative to after the GPU section header
