Hi W4ld0
First, is this "door" your trying to scale up a Segment type door, or an Entity door?
If it's an "entity" door then yes, Fragmotion will scale it up a bit, but it's hard to keep
the animation correct without messing up the bones. (but doable)
You have to select everything under Transform Options, Mesh, Bones, Correct Animation,
then Scale Uniform. And then it's still trial and error.
If it's a "segment" door then your best not to scale these as they are made to fit
nicely in a "segment" sized room. Scaling these up will make top of door stick through ceiling

best
Forgot to mention, Entity Workshop is great for static entities, but that's all.
My games never have bugs. They just develop random features..
Lots and lots of random features...
