Quote: This is a great idea if you want your lighting to look like crap. Sometimes you can get away with converting a regular texture to a normal map, but normally only for organic rough textures like dirt or grass.
Well dirt and grass are exactly the sort of texture I need this generator for
Quote: The blue channel of a normal map gives you the slope, not the height
But if it gives the slope then it wouldn't be that great deal to calculate a height out of it. You figure out a base height (could be the heighest or lowest point of the map but actually I have no idea how to find it), and then you could calculate the height of every other point depending on the difference of the slope to the previous point. Does this make sense or do I get it wrong?
