You are able to get the texture paths from your link and put them into an excel, then use excel formulas to build a lua table from it. It should look like this:
Lua Code:
local mapTexturesOrig = {
[1] = "/art/maps/map1.dds",
[2] =...
}
And built another one with the replacement textures, or use the same folder structure in your addon's folder, inside a subfolder "textures" e.g.,so you can dynamically use it for a replacement from your addon folder.
ReshadeMap/textures/art/maps/vvardenfell...
With a loop over the table you can do the replacement then.
Lua Code:
for index, textureNameOrig in ipairs(mapTexturesOrig) do
RedirectTexture(textureNameOrig, ReshadeMap.appName.. "/textures".. textureNameOrig)
end
