I have struggled for days now trying to figure out how to get a brick texture the right scale to fit on a building I understand roughly about texture mapping , but if you search for images of bricks on the net you will obviously get an image of a certain size and it will not be the whole side of a wall for instance.What I want to know in real basic terms is how can this texture be sized to fit on say the side of a house and still be the right scale ?
Does it involve a repeat of the image and if so , How to get the joins so the texture looks like a complete row of bricks ?
hope this question is clear and thanks in advance
