			''addition by stgatilov (Jan 2020)''

			The '''rotation hack''' approach described in this article is not supported by the game engine. It is known to cause numerous problems, including:

			* '''Culling''': When object is partially off-screen, it suddenly disappears.
			* '''Physics''': Collision and physical interaction with other objects is broken. For instance, a dead guard on a hacked carpet goes crazy.
			* '''Shadows''': Nearby surfaces suddenly become wrongly lit/unlit. Usually happens only at specific viewer locations.
			* '''Illumination''': Materials look differently. I.e. brighter/darker than they look on normal objects.

			Therefore, better use DarkRadiant feature to scale models.

			TDM 2.08 includes a very dirty hack under cvar: <tt>g_rotationHack 1</tt>. If this is set, then the game engine scales func_statics with bad rotation on load.
			This is done so that players don't have any issues in existing FMs.

			If you are a mapper, then either avoid entities with bad rotation (dmap will issue warnings about them) or test your map thoroughly with <tt>g_rotationHack 0</tt>.

Resizing models is generally not recommended but I do it a lot. It works fine with many models but there are a few fixes needed.

* This method does not work with any AI or corpses.
* It does not work with moveables or movers. (I am unsure about movers - it might be OK if they are symmetrically resized, eg, all dimensions doubled.)
* It does not work with ''all'' static models anyway. So you have to try it on a particular model then check it in-game to see if it looks and works correctly. It's a hack. This is how I do it:

Do not rotate the model first. If you have then first delete the rotation property. Otherwise the numbers might be too complex to deal with easily (try it and see!)

Give the model this property:

'''''rotation 1 0 0 0 1 0 0 0 1'''''

That mean unrotated scale normal. (a quick way to get the above from UNrotated is rotate 45 degrees then back again in top view.)

The 1's are the scale so double all sides would be 2 0 0 0 2 0 0 0 2
Or half width double height might be 0.5 0 0 0 0.5 0 0 0 2
Note that these are ''world'' oriented so if you need to rotate the model later you should anticipate that and change the side that ''will'' be turned that way after you rotate it! (experiement and undo and you'll see soon see what I mean. If you make a long table even longer then rotate it then now it is not longer but 'fatter'!)

Once you've done the above then you can rotate the model if necessary subject to what I said above.

The collision model is now 'wrong' (it's still the original size) so give the model the property solid 0. Now you and AI can walk through it so build a nodraw solid brush(es) inside roughly the shape (there are nodraw solid textures for different materials so pick the right one eg, nodraw_solid_wood so it sounds correct when impacted.)

The shadow will be 'wrong' (it's still the original size). Set the model noshadows 1 so it has no shadow. If you want a shadow then make the inner brush to be a real material like wood.

If there is a texture specular map (shinyness) then it won't scale so the texture might go unnaturally dark, almost black. Avoid those. But many models work fine.
