Looks nice so far. Some very cool texture combinations.
Unfortunately the r_speeds go up to 7000 in some parts of the map. I hope you can fix this a little bit, maybe with some hint bruhes or make sure that no face of the water reflect.
For the lighting I'll wait for the next beta. It's really hard to navigate at the moment.
You could add "gamemode""4" and "maxteams" "2" to the worldspawn.
To fix the bad field warning while loading the map you need to delete the value key on the low count flags.
And a few screenshots...
Red: There are vis errors on different ladders. Maybe detailing them or moving them a few units might help.
Green: Rotate this textures.
Red: I'd avoid this hole and make the top brush bigger.
Red: One more ladder. Looks like you forgot a small brush here. Or another vis error?
Red: vis error, try to move the arrow a little bit to fix this.
Red: Wrong textures.
Red: Also some missing brushes or vis error?
Red: I'd use the same textures here. Also the other base looks different.
Red: Maybe rotate the texture for these barrels.
Red: Looks a little bit weird. I'd make this brush bigger to avoid the hole on the right side.
Green: Same texture rotation for this barrel.
Red: Misaligned.
Red: I'd try to avoid splitting this texture, looks not very well. Make it a little bit smaller or bigger.
Green: Try to align these faces, bright<>bright and dark<>dark.
Red: Same here. Try to align these wood textures. Moving it a little bit would look more realistic.
Red: I'd rotate these faces.
Red: Move it up like you did on the blue side. Or just make it same
Red: Wrong texture!?
Red: Maybe it would look better to use to color texture for this small face, too. You did that for the left floor on the pic already.
Beta 5 is online @ [OTB] Beta!
