I think she has textured them properly, Jojon. Take a look at her screen shots in
this post - she has a texture MapInput panel, which she wouldn't get without creating a texture record.
I managed to get my animated textures working. I just deleted the old IPO record, saved the file and reloaded it (to make sure that record was flushed out of memory), then re-created it. And it worked!
What happens if you re-create your IPO curve, Kierra? If that doesn't work, would you be willing to post a zipped, packed Blend file of your world so that we can take a look at it?
