Every tutorial I've seen says to make the heightmaps 256x256 pixels, why is this?. Is there a direct relation in pixel to map size? I've made a heightmap 512x512 pixels and loaded it into visitor as a 256x256 map, so why do they ALL say use 256? Are they all copied from the same source of info verbatem, or is there a special reason?...
The main reason for asking is that 256x256 is quite a small map. I want to make a 512x512square unit map, should I use a 512x512 heightmap?...
If it makes no difference, why not use more pixels and make it easier to create detail on you/our heightmaps?...
