I'm just getting my feet wet with modding this game.
I decided to start with modding environment textures as I have a really nice library of high def dirt, sand, grass, rocks, etc.
I wanted to start with replacing the ground you see in Tatooine settlement which i have located as LTA_sand01 and LTA_sand02.
I replaced the texture with a same sized HD texture from my library overwritten as LTA_sand01.tga and LTA_sand02.tga and placed them in the override folder as a test case to start off with and see my changes.
However, the texture does not seem to have taken. I go to Tatoo and it's still the same.
I have skybox mods that are working fine in the override folder as .tga files.
The most likely case is that I need to edit more files than just these? But as I said, this is my very first project I would appreciate some assistance.
