Architools is a great program for easily making all sorts of custom houses but the instructions suck. They need to be rewitten to make them clearer. I still would recommend this program. Here are some of my questions so far. Q: Where are the door and widows framing supposed to be in Carrara to insert them in the door and window holes? Q: In which room are the shaders place? The individual parts of a building only seem to be accessable in the modeling room but I don't see how to add the shaders.
