I don`t know if I can post this kind of stuff here, but it is an idea I had which i think would be good, don`t know how possible it would be but to have it so when it rains it doesn't go though roofs of built structures, like I know its a small thing but I think it would be nice so when you go into I structure you have built or is pre built and it actually works as shelter and stops the rain, its just an idea i wanted to put out there see as i have no knowledge of modding so i thought id tell the people that know what they are on about, so if someone wants to actually make it a thing if it is possible, a little shout out or credit or something like that if you do make it and obviously tell me because id love to try it out
