Black/White would be best for bumpmap work. White=Raised and Black=Lowered, unless the bumpmap is inverted.

I'm surprised my project files were downloaded that much. I didn't think there were that many ShotCut users out there.

I would love to try shotCut to do the animations - probably easiest
but thats still future experimenting for me
-thanks for getting back to me

Now that i am understanding bump map a little better
maybe i can use this on the neighbors front yard Zombies invading
hmm... (scratching head)

Here's another animation I just made.
