Many thanks to both MostHost and RevOverDrive for their help and suggestions. It sounds like vertex painting would be the way to go…IF…this were an actual project. That’s good to know, and is much appreciated info.
In this case, however, I’m actually just trying to learn the scripting system (and to stay sane while self-isolating!). So, I’ve read MostHost’s post a bunch of times—it sounds like my simple project-for-learning is currently beyond my understanding of the scripting process. However, I’ll keep trying to chip away at it.
Thanks, again, for your help!
