hi guys, someone knows how to extract textures from a3t format? in playstation 2 is called amt, but in playstation 3 is a3t, try to extract their textures with a .py script that made a user called nexus the modder credits to him for his program, but only extracts the textures of the characters only that, with another type of a3t file that is not character does not extract it, here the .py and sample files

A3T Tools.rar

Some of them are DXT3:

yes I was just checking recently, in the #a3t script it only supports dtx3 and that is used in the file characters, the other #a3t files apparently use another type of dtx, dtx3 is not used in some #amt files.

I wonder if the script can be improved, I tried but I couldn't do it.

it's a very good script! but I still don't understand why you can't open other types of a3t, for example noesis won't let me view this a3t

The good thing, is that I took the time to research the a3t file, I'll explain what's here:

RED: Nº Textures in the file
Yellow: Texture index offset
Black: texture 1(includes bpp, dimensions etc in this area)
Green: DDS Header

this file contains only one texture

There is morton involved. Also width/height from table doesn't always match width/height from dds header. So script must be rewriten.

It's hard to make a struct just from one sample. Post more samples.

here you have more samples, I think each a3t has its own tempering .dds(header) is what I'm seeing in each a3t

Updated script. Now it should work.

thanks mate! so far I have tried 5 files and it works too well, I'll keep you posted, maybe based on this script, I can make a reimporter and an improved extractor

i have tried to make a .py script to extract the textures without depending on noesis but i couldn't when you have some free time or you want to do it could you make a script?

Sorry to tell you that but i am not good enough in that. You are on your own. Maybe someone else can help.

Anyway you must deal with morton algo.

You can do that easily with ReverseBox dependency https://github.com/bartlomiejduda/ReverseBox

Morton swizzle is supported.
