Well i've always thought previous snowy maps etc. looked unrealistic. In your first screenshot for example, the wood texture has no evidence of snowfall.
I meant more the well done snowy terrain than the texture choices. How about an combination with such a terrain and your textures?
- As for the texture sizing, I wasn't really sure what the difference was meant to be. I saw one texture in another folder at 128x128 so I just made them all that size. Are they supposed to be 64x64 then?
It's different depending on what kind of texture you have. For a barrel texture I think it's 64x64 and 256x256 for the hr4 version, yes.
- And the texture load problem, well i've no idea whats wrong there. 'Bad .jpg file'? What does this even mean? They've all been fine for me thus far...
BASEBALLDUDE is right, resaving the jpg files works for me. You should work on them again and update the download zip.
Some more stuff to fix and improve from the old map:
There's a PB_droptofloor warning when loading the map. It seems to be the missing second ammo item on the right side on top of the red teams ramp.
The map still supports the gamemode 1Flag without having a single flag. You should add the missing single flag and remove the team flags from this gamemode. Or just remove the gamemode from the worldspawn, flags and player spawns if you don't want to add it.
Moving some of the player spawns out of the corner to avoid spawn killing. Maybe change the angle value after that.
The lighting can be improved a lot in my opinion. Use the sun lighting more efficient with adding the keys/values. Maybe some more lamps or light textures can give the map a nice look, too.
Align all wood textures and use the same width for all colored wood brushes around the map (high).
I'm not sure if hint brushes can help a lot, because the map is very open and you can see almost everything all the time (apart from the way behind the flag down to the ice). It also looks like your hint brushes doesn't really work. Make sure to skip the non-used faces of the brush, otherwise it can make the result even worse.
