Extracting Textures

[darthdoull]

Hi there, I need help extracting the vanilla textures. I used a quickbms script to unpack descent2.hog but it gave me more compressed files and I don't know where to look. The script is limited to hog and pig files and it can't unpack the files in the hog file so I'm stuck. I'm also not sure where the textures are exactly.

Textures should be in the PIG.

I was afraid of that. I unpacked two pigs; ice and alien1 but there's nothing in them except folders. Inside the folders are random combinations of dat, ini, and txt files. Is there a way to convert or extract these into proper images?

There were some utilities that could extract sounds/textures/etc from descent and descent 2 called DTX and DTX2, the problem is they are 16 bit windows applications and won't work at all in a 64 bit environment. If you know and can jump through the hoops necessary (virtualization/emulation/etc) to get them working then you can download them here: http://www.cybertrash.com/shareware/dtx/

Yeah, I tried that before coming here and as you say, it doesn't work on my 64-bit system. I tried getting it to work in Dosbox too but that didn't work either. I'm not sure what else to try. I'll keep at it and thank you for the responses.

I'm not a programmer and I'm wondering if maybe someone here can take a look at this script and see if you can spot anything wrong with it. I have a hunch the script extracts the data incorrectly. It's doing its job a little too well, extracting the raw data from the images instead of giving me images. That's just my guess, anyway.

    goto 0

        getdstring NAME 13
        get SIZE long
        savepos OFFSET
        log NAME OFFSET SIZE
        math OFFSET + SIZE
        goto OFFSET
    next

else

    print "Error: unknown magic %SIGN%"
    cleanexit

endif

I'm not 100% certain, but I'm pretty sure that the images are palette references to descent.256.

Something else you can try if you have a level editor (i.e. DLE) is exporting the image from within the editor. It takes longer, but you do get a standard image format as a result.

[darthdoull]

Ah, the folders make a lot more sense now.

That's a good idea, I haven't thought of that. I tried DLE per your suggestion and it worked perfectly. It even gives me the frames for animations, feels like Christmas. Thank you so much to the both of you for the help.
