I knew it would be an easy fix. I have done the same thing, and overlooked a material, or forgot to add the alpha channel in the -da texture. Then when i test it i am like WTF?!! Sometimes photoshop makes an all white alpha channel if you forget to add one yourself.
You are asking a sins modding pioneer if he installed a mod correctly? LOL! The answer would be Yes. I did use LAA (though i dread using it). I installed it in accordance to the readme's instructions. However, I will re-install the mod, and test it again just to be sure i didnt miss anything (hey its possible).
If you need LAA to run the mod then the mod shouldnt finish loading at all correct? It "should" dump before it finishes loading, because sins loads almost all of its assets at game startup. With a few exceptions like sounds, but pretty much all of the textures are loaded. I am not so sure about particles, because there is a slight lag when a ship fires weapons, or uses an ability for the first time.
Does LAA even work in 64 bit windows 8.1?
I re-installed the mod, and followed the instructions TO THE LETTER. No Joy.
It seems the problem may be just one of the moon meshes may have its texture borked. many moons show their texture while some others do not. If the moons are randomly generated i can see how this is happening if its just one moon texture is missing, or miss-flagged.
More screens... No these are not shots of the same planet. Just many planets that look the same. The map is Chiss Ascendancy.
