Getting an object to fit inside a bigger copy of itself

I have a 3d model of a human. I have copied this and made it transparent and bigger. I wish to fit the original within the transparent copy.

I thought, easy, I will just scaleentity man,1.05,1.05,1.05 and it would fit. Wrong, this make the arms move farther away from the centre of the object causing them to collide with the old models arms.

I think I need a way of making an object 'fat'?!?!?

Is there a way to do this type of scaling? Anybody had this problem before?

Check out sswift's cell shading code:

(I believe it does something similar to the effect you want).

Yes, my code scales the object up like that. But it also flips it inside out. Just use the bit that moves the vertcies out by some amount in the direction of their normals.

Thanks guys, I'll give it a go.

Thanks Lee, I'll have a look at both.
