to make a model of your house, you can male it in your favorite modeler, texture it (using one texture, so that can be pretty hard
) export it in .X format, some modelers can export to .X by default but some of them require plugins, if you are using 3ds max you can get the free (i think) .X exporter pandaxporter, try searching the forums, thats where i saw it.
load the character in max and using the pandaxporter, export it to .X, if its not animated, you will have to animate it first, and make sure its all one object, and not several objects and it uses only one texture. the .fpe is just paths for textures and the model itself, scaling and other stuff. .X is the model itself
hope this helped
may god have mercy upon my enemies, I sure as hell won´t.
