Attachment Scaling

[Incognito]

Simple question, is it possible to scale the size of attachments?
... if so how?

with a model editor, you can find some tools and tutorials here

Is it not possible to change it for an individual unit in game?

Attachments are scaled to the scaling of the unit they are attached to, provided you tick the "scale attachments" (or something to that effect, it's under the "art" fields near the top) field. IE, bigger unit = bigger attachment.
Other than this, I don't think there's another way to do this unless you make a unit with the model and scale that to what you want, then make a trigger to get the fake model to follow the "attached" unit.
Or just edit the attachment model.
