I?m trying to extract the plane models from Crimson skies from the original xbox. Most of the assets are stored in bin files, they seem to be a package of files (tgas and meshes in most of them) because the file names can be read on a hex editor.

They are tgas in the file but are probably encrypted or compressed, because i don't recognize any pattern of a tga file



Any advice?

Don't trust the "tga" extension of the extracted files because it looks like the "original" name while the extracted file is a sort of raw image.

wow, that was fast. Thanks!

I will try to know what format are the meshes and the textures.

Thanks again!

here is a Noesis python script to open your tga texture samples
*script updated Nov 26, 2020*

supports dxt1, dxt5 and morton order rgba8888 and rgb565

type 0xe is xbox swizzled and i tried my best to get those looking right,
fortunately those types look like effect images or something, so they are
not really the important ones.

I was able to determine with texturefinder that the tga files where dxt1-dxt3 files but that script is great, i was getting some strange artifacts in the bottom of the images. Thanks!

Right now i?m with hex2obj trying to decode the format of the meshes.

Thanks!

first submesh in debris_metal2.x

the counts are stored as shorts right before the data begins

Thanks! i was really lost with the strip and the WordUV options. I will try to investigate to know what they do. I want to import the models into unity or whatever so i need to understand it right.

i?m not sure if the strip is optional, this is the last mesh from Devastator_fusalage.x, left without strip and right with strip




Edit: i think the uvs are somewhat not-ok , when i try to put the texture on the model they are totally wrong. They are not just inverted or something like that, i tried to rotate the texture and move the offsets and tiling values but no luck so far


should be like this:
