-The sea is made of two layers: the blue (floor) and the white waves (3dfloor right above the first one) and both's textures scroll in different directions so the ocean look spiffy as fuck. However I can't seem to get the 3dfloor one to move when on top of the first one, even though I set it to -move slowly- on it's original sector. So, how can one make a 3dfloor's texture scroll?
-What's the max texture size allowed? I made my ocean textures 128x128 to be sure but it makes them look pixelated as fuck and ugly from afar.
-Any tips on how to make the map look more colorful or interesting? Make the scenery look better? Grey rocks aren't exactly the funniest thing to look at.
