I also thought that might be the case, judging from how those options were still grayed out despite changing things up so many times. I'll give that link a try and see what happens.

EDIT: It works! Anyway, I tested Violet CLM's theory, and apparently having an animation as the first block in a different animation used for the Trigger Scenery fixes the issue with no destruction effects on the blocks themselves, at least to a certain extent. It still only works once, but it does add something new we can use in level design.

On another note, the WebJCS Sir Ementaler linked to seems good for illustrating a level in progress as well, besides collaborations. Though it doesn't properly display the Reworder changes I made to the level, you can check that link now to see what I was doing (or if the level was changed, look for SceneryTest.j2l).
