Trying to find the cubemap image to increase its resolution

Alright, I've got all the cube maps in their own pacakge now but I can't seem to get changes to show up in-game. That or I'm missing one.



Here's a TV scaled up to give a view of how bad the cube map is. But...the map in the TV doesnt seemt o match any of the ones I've got in my file. I'm also fairly certain this is thes ame one used in windows and it doesn't seem to affect them, either.

I've modified the largest file to be larger and smoother, but when that didn't take, I added giant black circles to it to make it very clear in-game if anything was changing and it's not. Any ideas?

On a second check, I thought maybe this was the small simple square map, so I reduced the noise on that one by a lot, and still no changes in-game...
