Using 'decimate' to reduce polygon count / model detail

If you have a model with too many polygons (for example something you've found online, or output from a scanner) you can quite easily reduce the amoung of faces in the mesh, though you may mess up your UV map / texturing.

It's pretty tought explaining how to do anything in Blender, but if you can find all these buttons then you've found the decimate function:

Maybe if helps to say that you'll find them in left>right/top>bottom order, like how you'd read English.

Once at this point you enter a nummber in the 'Ratio' bit, or use it like a slider and watch how it effects the model. I tihnk for this model I used something like 0.01. Use the middle mouse to rotate the object and make sure you've retained any details you want to, then when everything's ace click on 'Apply'.
