i created a multi/sub object material.

1-3 work great, map channels for the bitmaps on these materials are 2-4. on my 4th material, i set the bitmap to map channel 5 and i was not getting the bitmap to show up properly. my object had 4 uvwmap modifiers on the stack.

it might just need to be closed and reopened, but i wondered if there's a limit to map channels?
