That sounds promising. Would it be something that could be applied to a single door … or would all doors be affected? I don’t know about this side of things, so (as rjshae says), it needs to be done by somebody who may know what they are doing.
Is it something you could give more instructions on?
OK, I tried searching for “DR_OPEN1.GR2” but could only find some references, and then to do with doors made by other people and not “official doors”. It may be that they are in a compressed file, but I have not found them yet … If you can give me their location that may help save me some searching.
