Unwrapping MS3D Model

I was playing with milkshape today, and what started as a box sorta evolved into a little building, which is much more promising than the horrible lumps I usually manage to produce when it comes to 3D modelling.
Anyway, I decided to try and unwrap the model with LithUnwrap like was done in the milkshape models from scratch tutorial here...
Anyway, I'm not entirely sure what I'm supposed to be doing... I grouped the model into several sections, and then loaded it up in LithUnwrap, and I'm able to resize and move around the first of these groups as a square on the thingy, but all the other groups just seem to be a point... Is this how it is supposed to be? Perhaps I'm not meant to group things like that? Maybe there is some trick I'm missing?

Anyway, any help would be much appreciated. =)

If your stuff is just a single point, it means it hasn't got any default mapping.

You'll need to use the texture coordinate editor (ctrl+T) in Milkshape on such objects, and use the "remap" function to lay the sides out properly.

I'm not sure if LithUnwrap has this ability, it might.

Ah, thanks, I'll try that when I get home. =)

Sorry for double-posting, but I tried that last night, and I couldn't get it to do anything. =/
All I'm seeing is a blank grey window. And nothing all seems to happen when I press -any- of the buttons... =/
Maybe it's something I've done or not done beforehand that is stopping it from working for me?

You have to apply a blank/template/whatever texture first. You can't map to a non-existant canvas.

Ok... I think I'm getting this. Kinda...

I'm not sure what I'm supposed to do grouping-wise, though. For example, if I was unwrapping a cube, would I group each side as a seperate group? If this is the case, am I to expect have have about a million groups, or is there something I'm missing?

Cubes have a default UV mapping setup, so you can take a whole cube straight into the TCE and use the scale tool to fit every side at once to a certain block.

You used any Geospheres, or the Create Face tool? Those generate things with no default UV mapping. Cylinder ends are similar but less, so.

Um, well, it started as a cube, but then I extruded it... A lot...
I didn't use any geospheres or, well, anything basically... I'm not very good at modelling. ^_^ (And that's the nice way to put it. =P)
