Costume Forge: wearing the pieces together

Put your saved pieces on one body at once and find out what collides — where a pauldron fouls a helmet, or a gauntlet stops an elbow bending — before you cut foam.

Pieces that each fit perfectly on their own can still be unwearable together. A pauldron that clears your shoulder standing still can foul the helmet when you turn your head; a gauntlet can stop an elbow bending. Costume Forge is where you find that out on screen rather than after a weekend of cutting foam.

Costume Forge explaining that a costume is several saved pieces worn at once on your own measurements with the clearance between them checked. — A costume is several saved pieces, on your body, with the gaps between them checked.

How it works

Model and save your pieces
Costume Forge assembles what you have already made. Sculpt each piece in Piece Forge and save it — a helmet, a pauldron, a gauntlet, a greave.
Wear them together
Add saved pieces to a costume. They are placed on your measurements from the Measuring Room, not on a generic mannequin, so the clearances are yours.
Read the collisions
The forge checks the space between pieces and shows you where they overlap or leave too little room. Fix it by resizing the piece, moving it, or accepting a strap that sits differently.

Check the poses you'll actually be in

Standing at attention is the easy case. The costume you have to survive is queueing for four hours, sitting down to eat, and getting through a doorway. Check the shapes that matter for the con, not the hero pose.

Linking a costume to a build

A costume can be attached to an entry in My Builds, which keeps the plan and the progress photos in the same place — what you intended beside what you actually made.

Assembling needs Adept or Archmage

Opening Costume Forge and seeing how it works is open to everyone; assembling a costume is an Adept feature.
