Chipp Walters, I read through your tutorial, but I can't see anything new I should be doing. Monsoon, "Diffues Button" I don't see that in Chipps tutorial do you mind telling me where it is in Vue? Thundering1, you said: "it's the pixel size - a 256x256 pixel image will give you jaggies where an origianlly 2,048x2,048 will not - doesn't matter if it's 300dpi or 10dpi - it's STILL x-amount of pixels by x-amount of pixels. The higher the cleaner" I thought this was the case too, but I made the height map for this image at 2400 x 2400 pixels and it still looks jagged. Here's the steps I took 1. I created a Standard Terrain (the default is 1000 x 1000) I changed the size to 512 x 512. I also tried with the terrain set to 1000 x 1000 2. Then I created an image (height map) in Photoshop with these settings. (2400 x 2400 pixels) -300 ppi -Saved as greyscale image 3. I then selected "Picture" and loaded my image image. 4. Rendered the file. One thing that still confuses me is how do I know what size to make my "StandardTerrain" and does it matter? If it does how do I determine the correct size? I also remember read in the Vue manual that Standard Terrains are lower in quality than Procedural Terrains. So I guess there's no way to create a custom terrain using heightmaps in Vue unless you want jagged edges. I was hoping I could use a custom height map I created for a project. Maybe the next version of Vue will address this. It's too bad Vue cannot use heightmaps with procedural terrains either. This is disappointing... Thanks for all of your help though!
