{AS far as the tex maps go they possibly are 4000x4000 - I wouldn't know nor where to find that out. } There are many ways to find out the resolution: 1) Open Windows Explorer, go to the folder with the images, and click on the file. Explorer should display the size (in pixels and k) in the botton status bar. 2) Open the file in any image-editting software. Then, go to to "Image Size" and it will show the size. Unless you are doing a super-close up or a super-large image, I would argue that there is no reason to use a 4000x4000 image map. Try reducing the size of the image maps to 2000x2000 (or smaller) and then try to re-render the scene. (Make sure you back up your original 4000x4000 image maps first.)
