While we're on the subject of texture size, I'll expand a bit on the background issues: First, there are a couple of technical limitations: power of two sizes, and a maximum texture size of 4096x4096. Getting the technical part out of the way we come to the tricky part. My opinion is that texture

Hi Yves, The issue here is that some of these textures are really large, and thus have the potential to limit performance for users with lower-end machines. Thus, I'm interested in guidelines/policies regarding texturing the terrain, what sizes are recommended or usable etc. I also agree about ab

Hi Adrian I think quality textures like yours goes directly to the main repo ? On the other hand I heared there is probably central "scenery repo" coming up (a separate repository and/or database). Maybe also for developing textures and to store "origins" or base material ? Green as I am I sta

Hi everybody, I have been doing recently some terrain textures experiments, mainly using aerial imagery from USGS and some personal photographs. I have managed to get a number of high resolution textures, and was wondering what the official policy is regarding terrain, and whether they would be
