(Sorry. I'm terrible at explaining myself) So I've made the model for the house, as of right now, i'm just doing a simple box house, I've made the base. I've tried to do the physics with no luck, I've tried different methods, but there's something i'm not doing or understanding (I've never used blender before) so i'm a little lost. The model I made successfully uploaded to SL, but i either cannot walk inside of it, (even when its turned into a prim) or it will remain convex hull, and be completely passable. I've seen a demonstration for a simple box type of room, which I tried and it worked with no problems, its now the bigger model i have the issue with. if anyone could give a demonstration with the model i have i would greatly appreciate it (just message me IW. Thank you !
