I am interesting in changing some of the textures within IGI. I found your project, and I decided to give it a go.
I have tried to use the 'Texture Editor', when doing so, I am given the message 'Textures fail to load from path'.
My work flow is as follows:
Load up Project IGI 1 Editor.
Go to Texture Editor
Click on 'Select Texture'
select the *.res file
The application then extracts the .tex files from the .res file within the location and creates the .qsc and a textures directory that contains the *.tex
I then get the error showing 'Textures failed to load from path'.
If I go to 'Select Textures' and try the base directory containing .res, .qsc and the textures directory, I get the same message. If I go to the base directory textures (level1\textures\textures*.tex) and select this directory I also get the same message.
Id appreciate if you could let me know if Im doing something wrong, or if there is a bug.
I have also attached some screenshots showing the issue.
