is there a way to rip textures with this tool? #11

Hi again! you might remember me from our last talk about the 3d models. it works for me but I noticed it only rips the models and not the textures so I was wondering if there might be a solution to rip not only the sprites from those games but also the textures? would be really nice to save those!

There is no textures in the game. What you see on models is some kind of shading done by the software renderer at the very last step (when filling the pixels).

Here is the different materials used by the game :

You can fake those in Blender with shaders. See this message for more info. Gradients can be simulated by mixing two colors, depending Window coordinates (from "Texture Coordinate" node).

AITD model viewer also generate fake UV coordinates for it's own purposes (that do not exists in the game). Those are exported and can be used in Blender.

the backgrounds are still covered by sprites right? would be nice to find a way to get those thanks for clarifying about the textures! I could screenshot the models up close with the viewer to copy the colors and make up my own set of palettes with exactly the ones used from the game so I don't have to make the colors myself using Blender. It might be easier to apply the textures using material as I don't need to make any adjustments for the texture to appear how I want it if its only solid colors and no other complex details. Plus screenshots would make a excellent guide to help myself remember which part of the model used that color and where to apply it.

Im not a expert with Blender but I am familiar with some of the basic features as I used to play around with Blender since 2017 lmao.

Time Gate has textures and those are exported by model viewer.

EDIT : to extract backgrounds, you can use jmimu tool as suggested in his message below. If you need to export some other data, please check this post.

Sprites : there is no such things for backgrounds. Each background contains a set of 2D polygons, used to "cutout" some pieces : background + 2D polygons = what will be drawn on top of actors to cover them

Hi, If it is of any help, my pak editor (https://github.com/jmimu/AITD_PakEdit) extracts the background images with the correct palette.

Quick update: it seems PakEdit can only extract AITD1 background to BMP (or at least I haven't been able to make it work with AITD2 and AITD3).

Due to popular demand, I have created a new tool that extracts all backgrounds automatically (with correct palette) : https://github.com/tigrouind/AITD-tools?tab=readme-ov-file#pakextract

It should work with all game versions, including Time Gate.
