I put your rule into my scene, and a couple of textures in the locations as you do. I don't encounter your problem, unfortunately.
Here's some thoughts:
- I see no version in the rule, which should cause you to have a compiler error. What version of CE are you running?
- Sometimes I've had problems trying to apply textures from anything other than the assets folder.
- You are using absolute paths to the textures, which is not a great strategy in general.
So those are just thoughts, not solutions. If you can't figure this out, I would like to see the project file if possible. Please let me know if you do or don't solve this. I'm following this discussion now.
