Texture Mapper

The Texture Mapper is a tool intended for texture modders. It can find where a texture is reused across the other three Mass Effect games, making use of the many textures that were reused between the games.

The tool was originally made by myself to make the development of ALOT easier, and I am now releasing it along with the source code for everyone to use.

WHAT IS IT ?

There are tens of thousands of textures in the entire Mass Effect Trilogy (11 000 for ME1, 8 000 for ME2, 27 000 for ME3). Additionally, thousands of these textures are reused across several games of the trilogy. Sometimes Bioware uses exactly the same texture from one game to the next, and sometimes they just do some changes (downscaling, upscaling, changing colours, brightness...). Some textures are even reused multiple times in the same game with only minor differences.

Each texture in the trilogy is identified by a unique identifier (a hash that looks like this : 0x0215D5EF). This hash is what modding tools like MassEffectModder use to find and replace textures.

We have built a database of such textures for ALOT, partly using image comparison software, partly by comparing textures manually. Currently, around 7500 such textures have been detected, documented and organised into over 3000 groups of very similar textures. The complete list is available here.

OKAY, BUT WHAT'S THE POINT ?

The goal of the tool is to make the most out of the textures you made, by showing you where your textures are reused, in the same game or in others. You can also choose to have the tool automatically port all your textures to another game.

An example :  you select your textures from the Texture Mapper, and tell it to port them from ME3 to ME2. The tool will go through your textures, find the hashes within their filenames, and from this build a list of the duplicates in ME2 of your ME3 textures. Optionally, it will also copy your textures into a ME2 subfolder, and rename the copies to their ME2 name and hash.

NB : the tool can be used on Windows and Linux. It's written in C++ with Qt 5. 12.

I NEED A TUTORIAL

Here's a gif showing how to use the Texture Mapper to show the many reused textures of the Terminus armor (ME2), in ME2 itself :

And here's a screenshot of the resulting files, ported from ME2 to ME2 :

And here's an explanation of the the results displayed within the Texture Mapper :
