hi Peter,
thanks for the reply. i have only ever needed to create basic objects in AC, and therefore don't know where to start...
how do i see a copy of the macro for the 'normal tile' roof surfacer? am i right in thinking that i can then get this macro to create tiles using my own custom tile object? once i create my own custom tile, how should i save it? and how much of the macro would i have to customise?
if this is too complicated to explain, then don't worry, i will continue to use textures instead as at this stage it is not essential, more something that i would like to be able to do.
