For those following this thread, I've figured out what I need to do. The attached image (sorry for the size and compression), shows what I've been trying to accomplish. It took some experimentation, but I've come to realize the errors of my ways. In this case the ability of C4 to do realistic landscapes in many resolutions. The image has 3 terrain masters, 5 terrain objects, and 2 fog objects of different colors. The sky is a spherical background images made in C4 and rendered to 2048x1024 (a lot faster to render than trying to get the sky AND the terrains together). The terrains are res'd at 2049 (on the left) with the applied textures, and I rendered them at 257 (on the right) and they looked almost identical. So what I'm left with is the knowledge that terrains put together can be at low res then increased depending on what type of POV you want. What's the outcome? Just trying to see what I can do. Ken
