I have an airport beacon that I made and it rotates. I want to attach a green light effect to the green lens side of the beacon and a white light effect to the white lens side of the beacon and have the effects move with the beacon. I have the effects created but when I try to attach them now they don't move with the beacon.
Attachpoints made in MCX are always attached to the root node of the scene. So therefore they are not moving, then the attach point needs to be placed under the animated node. Like I wrote before this can't be done in MCX yet, it's on the wishlist. You would manually have to edit the X file.
I just Googled a bit for it and it seems a drag and drop of nodes in the hierarchy editor should not be too hard to implement, so I'll try to give it a try soon. Just not now, since it is time to go to bed and get some sleep now.
THIS IS EXPERIMENTAL AND ABSOLUTELY NOT FOR THE FAINT OF HEART! YOU HAVE BEEN WARNED!
Unless it's already common knowledge, here's a short how-to on how to add an effect to a specific part in a hierarchy. This is especially useful for adding lights to flexing wings or moving parts.
I've successfully managed to attach a nav and strobe light to each flexing wingtip of an aircraft with this procedure, using nothing else but Notepad2 and MCX.
You really need to be comfortable with editing very large text files, finding stuff in MCX' hierarchy editor and, of course, adding effects in the attached object editor. A text editor with syntax highlighting, especially for bracket pairs is almost mandatory.
