Your conversation is helpful, i'm still not sure what to do about my glass... i thought about using only vertical connection to avoid having that invisible barrier on bigger areas. Do you know if it's possible to apply it only on the side faces? My knowledge on CTM is so rusty, i forgot everything.
Whoa... it's a whole new game!
I didn't have as much free time as i hoped the last week, but i finally managed to redo my custom sky stuff... what do you think? Too much? The graphics are still pixelly, i didn't want to use realistic clouds. It was too much work, especially the whole distortion thing... don't want to do that again. There's a cloudy sunrise, less clouds until they're gone at noon, then lots of clouds in the afternoon until they slowly fade away at sunset.
Made a timelapse of a whole day:
