Rigid Fit

Aligns one mesh to another using nothing but a move, a turn and a scale. No vertex moves relative to any other, so the shape is exactly what it was - it is just somewhere else.

When to use it

Aligns one mesh to another using nothing but a move, a turn and a scale. No vertex moves relative to any other, so the shape is exactly what it was - it is just somewhere else.

This is the first step of every wrap. Non-Rigid Fit and Elastic Conformer both work by looking for the nearest bit of target surface, and that only means anything once the two meshes already sit on top of each other. Feed them two shapes standing in different places and the very first pass matches the wrong things.

The Transform output is the move it worked out. Send it through Apply Rigid Transform to put that same move on the clothing, the landmarks mesh, anything that has to travel with the body. Solving each part separately is what makes the parts drift apart.

How to use it

1
Connect the mesh to move and the target to align it to
2
Decide whether rotation and scale are allowed
3
Click Apply

Pins

InputsOutputs

Pin	Type	Description
`Mesh`	Mesh	The mesh being moved.
`Target`	Mesh	The mesh being aligned to. It stays where it is.
`Landmarks`	Landmarks	Optional. Landmarks wired in here ride along with the move so they still sit on the surface afterwards. They do not steer the alignment itself.

Pin	Type	Description
`Mesh`	Mesh	The moved mesh.
`Transform`	Transform	The move it worked out. Send it to Apply Rigid Transform to put the same move on other meshes.
`Landmarks`	Landmarks	The landmarks you wired in, shifted onto the moved mesh.

Settings

Setting	Type	Description
`Use Rotation`	True/False	Let the fit turn the mesh as well as move and scale it. Off leaves the orientation exactly as you had it.
`Preserve Up Axis`	True/False	Keep the mesh upright and let it only spin around the vertical. Turn this off and the fit is free to pick any orientation, which on a roughly symmetric body means it can come back lying on its side or upside down.
`Use Scale`	True/False	Resize the mesh so it matches the target's size.
`Non-Uniform Scale`	True/False	Allow a different amount of scale on each axis, matching the target's bounding box rather than its overall size. Useful for a body that is the right height but the wrong width. Leave it on by accident and it will squash a head to fit.
`Align Floor Level`	True/False	After aligning, slide the result up or down so its lowest point sits at the target's lowest point. For anything that stands on a floor, matching the feet beats matching the middle.
