Ok im using 3D World studio and have managed to make a model using multi textures as shown below...
And this is my model directory below...
And this is my fpe file...Which is Default apart from my model name and "ONE" Texture
-------------------------------------------------------------------------
;header
desc = cm
;visualinfo
textured = brick.jpg
effect = effectbank\reloaded\entity_basic.fx
castshadow = 0
;orientation
model = cm.X
offx = 0
offy = 0
offz = 0
rotx = 0
roty = 0
rotz = 0
defaultstatic = 1
materialindex = 3
collisionmode = 1
;statistics
strength = 25
explodable = 0
debrisshape = 1
;ai
aiinit = appear.lua
aimain = default.lua
aidestroy = disappear.lua
;spawn
spawnmax = 0
spawndelay = 0
spawnqty = 0
-----------------------------------------------------------------
The trick is to pick a main texture ( Brick in my case ) and use that texture hidden on a face of all the other brushes or blocks...
So in my model..The underside of the base has a brick texture..
The lintels on the window and doors have a brick texture on the upperside
The roof has a brick texture on the underside...
So in the fpe file the textured command is "Textured = brick.jpg and all the other textures fall into line and appear on the same brush..
Like I said im using 3D World studio so I hope it may work with other software and maybe help you guys out .....
Only been using it for 2 days so sorry for the big post if I have over complicated the explanation
