I fear this question has been asked a million times before but I couldn't find the answer. How many pixels ( for texturing ) are in a 3D World Unit ?

If I want to match my texture height ( roughly ) to a wall height, for example.

ok, you need to know a bit more about how it works, basically your texture can be any size, and when mapped onto a plane, providing it has normal UV coords, will be stretched or compressed to fit that plane. usually its best to keep all textures square, as when they get to be used by your graphics card, it will automatically resize them to a square anyway. therefore, its best to do it on your terms, rather than your hardwares, plus it'll improve speed.


as for "3d units"... 3d units are an arbitary size, they don't really have a real world counterpart. you can use them like real world units, by setting some rules in your head, such as 10 3d units equals a metre in real life.

I don't have a sig, live with it.

Thanx manic

I would think that the 3D Unit at GRID=1 and ZOOM=3200 should have a real world measure measure. An approximation will work however.
