If I name this texture: A_Alliance.dds it does not show up.
But if I add anything to it, like a number at the end, it shows up:
The other alliance textures are doing the same thing: D_Alliance.dds & E_Alliance.dds
(all the others work, its just these alliance textures)
I had similar problems with textures when I updated Social Indicators. It seems there are a few words that we can't use in the file names. I think aldmeri was one of them. IRC I had to rename it to adominion in order to get it to work. I also had a few others, but don't remember them.
Ah, my guess was maybe A_Alliance was a reserved word, or one already used by the game in some texture table somewhere, but thought maybe I was just missing something.
Thanks for letting me know.
I believe this issue has nothing to do with texture names. At least when I rename texture in SkyShards to "A_Alliance.dds", it is still correctly loaded and displayed.
I think there was once a similar topic and it was noted that it's not enough to /reloadui, you have to log out, or perhaps even restart client for texture cache to flush out.
Logging out & back in didn't work.
That problem occurred on the NA server, but I just had the same problem on PTS with another addons textures not showing up. Logging out & back in didn't work there either, but then I tried deleting the ShaderCache.cooked and then reloaded the game to let it rebuild the file & that fixed it.
