I see from a thread below that someone else has discovered a problem that I had. Since I have had the answer to it from e-on, I had better pass it on. It is seriously obscure. The problem is this: suppose you wish to apply a brick texture to a large wall. If you use the "automatic" mapping mode for the bitmap texture, Vue 5i will try to fit the bitmap to the wall's uv co-ords (I think); anyway, the result is that the texture is mapped very badly. Change the mapping mode to "faces" - much better! However, if you want to use your bitmap as a bump map as well, you hit a snag. The bump map is still mapped as "automatic", and it doesn't fit the texture. Now in Vue 4E, this was no problem, as you had the same mapping modes for the bump map in the materials editor as you did for the texture. So how come Vue 5i can't do something that Vue 4E could? Here is the solution, and it took me a while to find it even when e-on told me where to look. Go into the function editor from the bump map tab in the materials editor. You should see a little box in the main display showing the bump map, and another rendition in the lower screen area where you can rotate it, invert it, etc. But not change the mapping mode. In the main display, above the little box there is a little symbol shaped like a filled-in U. Click on this. Now the bottom display has changed and the menu appears to allow you to change the mapping mode. Problem solved! Now would you ever find that intuitively?
