I am always in awe with how many people still run XP. If I were having problems with new software behaving correctly under my very old OS I would naturally assume the OS to be the bottleneck and upgrade. Glad to hear you are now enjoying the intended level of detail for user created models.
I don't see why this should be a memory problem. 4096x4096 points, lets say each represented by four bytes make around 68MB RAM. I have 4GB, XP32 uses 3GB. Thus i can put the map 50 times in the memory. That should be ok. Plus i was able to make the processing using Photoshop and the Nvidia plugin as described.
I'm glad for the sticky but how do you import an airfield?? Is it the same way as described for importing a swap file? a member made a photofield of our old airfield. A friend of mine and myself just bought 6.5 but don't know how to import the files. It is a zip file with 14 files in it.
Sorry, you may already know this... the file is an AV (aircraft variant - physics only) file... do you have the required EA (entire aircraft) related file? What version of the RF software are you using?
