I can't say I have trawled through every bit of information on the web, but I can say I tried hard. I have been trying to work co-operatively with displacements, but they are pushing me over the edge lately. Why does one side have to be invisible? This ruins everything I hoped for. I may have used the dish from Hydro - complete with the two entrances. However, working the tunnels getting to them is a nitemare when the bottom of the dish is invisible D: Anyway, the dish has become a slightly integral part of my map, and I would rather find a work-around (or even better, solution!) than start again from scratch and make something completely different. I would like to know how to deal with this invisibleness. Also, if you look at the dish in Hydro, it has a 'ring' that goes around it and connects it to all the other ground displacements. I wanted to use this ring to make a wall around the dish, but it is the wrong way around (the invisible side being the one I want textured). If i flip it, then it curves at the wrong angle. Help?
