I dont know if it can be done in the editer or not ,But it may be possable to resize it in Gmax and export it larger ,From what Ive heard anyway. I want to do the same thing with some unites to make new Titan models .

yeh i was kinda thinkin i might have to use gmax but i've only used it once before an all i managed to do was load either a hoplite body model or a head model and i couldnt load the texture i wanted to play with. not that in this case i would touch the texture. basically i'm tryin to make it so walls are slightly bigger so they look cool and helepolis are slightly bigger so it looks cool when theres siege going on.

Same here ,I dont know alot about Gmax and Im too busy with my new Titan mods to learn right now, I guess if I want it done Im going to have to learn Gmax .

GMAX isn't very hard, pretty straight forward for the basic things atleast. Anyway, you could just resize it in GMAX but you'll have to change it slightly, otherwise the export script won't notice any changes and it'll not be changed..

cool would you be able to write me a little tutorial on how to do it cuz i sort of dont really know what i'm doing with gmax i'm like level 1 Gmax.

If you do that for a unite will you have to make new animations.

I already did that.

No, the animation will remain there. Although if you heavily change a model you could end with a messed up animation. But that isn't the case with just resizing.

@Argie: Gmax straight-forward??? The UI alone gets me in circles. (Blender forever! )

Anyway...
It actually will mess with the animation. If you scale a unit (and you have to scale the vertices directly otherwise the export script won't pick it up as the model itself hasn't changed) the animations do not change.
That is a bad thing. If one vertex moves from the bottom of the model to the top and you halve the height, it will move from the bottom to twice the height.

The way to work around this is to use the fact that modifiers are picked up by the script. There is a convenient modifier called XForm. Modifiers - Parametric - XForm.

That will add an entry to your modifier stack (Gmax incorrectly calls it "modifier list" but a last-in first-out setup is called a stack) called XForm. Expand it and you will find two things: Gizmo and Center.

Center allows you to adjust the point that the transformations center upon (not the pivot point). If you move the center near a unit's head, it will scale and rotate around the head.

If you select Gizmo, you will be able to move the model as a whole (after animations are applied, which is why they do not get screwed up) in such a way that the export script still picks it up.

So, to scale an object, first move the center to the point where the unit's feet touch the ground. This avoids nuisances with having to readjust the unit's vertical height. Then, select Gizmo and scale.

Export, etc.

Another advantage of storing this in a modifier is the duplicating ability. You can right click the modifier, select Copy. Then, open your next model, right-click the stack, select Paste.
This way you can adjust all the models equally.

They do call it a "modifier stack" (well, at least in the 3ds max help files, but it should be the same in gmax) - you're probably misinterpreting the words "Modifier List" which appear in the drop-down list of modifiers that you can apply

Wow. I'm an idiot. I ought to pay more attention to whether something has a little arrow at the side. Never noticed that before.

Bleh, they should label it something like Add a Modifier.
