Thanks for the feedback, the emitters definitely make it feel more like the vanilla forcefield doors. I like the end result (although the still screenshot doesn’t quite capture it), and I have updated the forcefield version with the emitters. I have also added a subtle plane of static similar to mydoor2.
Instead of adding duplicate emitters, I actually increased their Y dimensions to fit the opening height. I also ended up tweaking a few parameters to suit the larger opening. (Side note, it looks like the emitters on mydoor2 are actually not symmetrical, although I can’t say that it’s noticeable in-game.)
