Gog- that may be because you were already working with your disk (virtual memory) due to needing the extra RAM. It would therefor have to read from the virtual memory area on the HD before it could write it to the regular portion of the HD. daemonknight- If you are using a photo texture for your stonework, you could make a copy and resample it down in an external editor. That would save you some memory space as bryce stores images as completetly uncompressed bitmaps. This would also have a side benefit of reducing the visual size of the blocks in your wall texture to a more realistic level. I think you might also have the bump inverted. The mortar seems to be extruded rather than inset. Nice model so far, seriously. Looking forward to seeing where it goes.

Pass no temptation lightly by, for one never knows when it may pass again!
