Ok, first things, to answer your first question.
Quote: "just made a gun my 1st question is how do you count the number of polys in a model?"
To get the poly count in truespace, go to the Model side and right click on the mouse pointer icon it should give you poly (quad) count. For a triangle count, copy (click the icon with two cubes and a arrow to copy) and press the trianglify icon within the mirror section of the model side. and read the new values. Delete this object, if you are not done with modelling. Keep the original in tack.
second of all that is a very good gun, Good job, have you uv mapped it yet.
lastly Truespace have two sides to it, a model side (which I mostly use) Because it is the side where you can deal with small objects and large with accurate placement and polygon control, while the workspace side (the side you seem to be using) is made for large scale modelling, which is meant to be organic in nature, this side is more artistic and since this side can take up to 1 million polys, the poly counter is not present. If you are making models for a game its best to use a balance of both sides' modelling capability. I.E the model side allows you to draw directly to 3D polygons or make your own, however the workspace side allows the user to do Boolean operation as many times as you wish.
However one thing I can't seem to master in truespace is animation,
But the furthest I've reached with that was on the workspace side.
I really hope this helps you as well as other.
