1.
On the Material Properties rollout, turn on
Gen. Mapping Co ordinates.
2. Change the Map Channel value to 2, and turn
on Gen. Mapping Coordinates.
3. Change the U and V tiling values for map
channel 2.
Now when you assign a m apped material, maps
on map channel 1 use the default UV tiling,
while maps on map channel 2 use the channel
2 ti ling. An easy way to see this is to create a
checker (page 2–1638) map on channel 1, and
make one checker color another checker map
on channel 2.
