Wow. hmmm.. ok. that happens.. lol... I LOVE that multi ambiance sky !!! ok.. let me share my excitement :p This is a multi sky surrounding. Bascially speaking you add this as a furniture to your room. It then contains a node (yellow dot). With that dot you an move or resize the sky. It's very interesting to change its dimention depending on the atmospher you want to give. Now this sky is special. You can decide if it's day with a pure blue sky, or a falling day or the night. You can also add clouds for each time of the day. You HAVE to try this in your rooms !!!
