You should see now that we have this image displaying on the ground plane we have made. This original image, CW_cell_grid.JPG, was not very good and remember I said we were just going to use it for out initial proportions. So, what I did was to go back to the sim and zoom in so I just saw one complete cell at a time and took screen shots of each of those I have in the original texture. Cropped each of these single cell screen shots to the red and blue edges. These new images will have much better resolution and show more detail. I named each of these with respect to their cell number, like CW_cell_21-19.JPG CW_cell_22-19.JPG and so on. Now I have 12 new images. This is why I made the Mulit-Material.
I close the sim and the imaging program and return to gMax. I open the project and both the Material Editor and the Material Browser. You can minimize the Browser, I open it to reduce the chance of gMax crashing when I am naming material as it so often seems to do. In the Material Editor I set the number of slots for the Multi-Material to 12. Each sub-material will have one of the NEW images as its diffuse map. The first sub-material is changed to the first cell image from the original overall image and then I just work my way down the list naming and assigning diffuse maps. Once I have finished with all of the sub-material, I am ready to apply them to the plane.
With the plane selected and in poly sub-object mode I select the top left corner poly (21-19). This poly should already be assigned to sub-material 1 by default. Now I apply a UVW Map modifier, then hit the View Align and Fit buttons, then Collapse the Stack. Select the next poly, 22-19, change the sub-material assignment to 2. Apply a UVW Map modifier, then hit the View Align and Fits buttons, then Collapse the Stack again. Keep repeating the process till all of the grid squares are done remembering to increment the sub-material assignment for each poly. Be sure and deselect the last poly when your done. Once you are done with this you should have a much clearer plane so it would be a good time to SAVE!!! and maybe take a break and get something to drink. We ARE on the down hill side of this now.
