How to Make a 3D Scan of a Dress fit, conform and move with an avatar?

I have taken 65 pictures of a garment and using Reality Capture software, it is now a 3D model.

How do I put this 3D model of a dress actually on my avatar?

Ideally, it will fit and can be edited to fit and I can add trims etc.

Any ideas will be greatly appreciated!

  You don't.

  In CLO3D the interpolation of a scan is geared only to the avatar and the rig of an avatar.

  If you are assuming that object import as garment will allow you to simulate a garment with all the constraints of a CLO3D made garment you are way off scope, as a single mesh object converted to a cloth garment will only have > one < cloth preset and none of the seams, layers, or construction or pattern drafting complexity or constraints will be present - as you would typically see in a CLO3D drafted garment. Apples and oranges.

   

  This means in terms of animation that you are extremely limited (using a object to garment in CLO3D ) relative to a CG animation pipeline for a raw mesh when  yes you can place additional animation constraints on an incoming object mesh (eg: rig, weight painting, polymesh groups, vector trajectories, animation curves, blends, groups with modifiers etc, etc). In CLO3D when you import a single object as a cloth garment it has only one constraint > the fabric collision preset at fixed re-interpolated mesh density  > with the avatar. All the nice detailing you get from a hand crafted CLO3D pattern based garment project will not be present. So that is a BIG problem if you are thinking you can retain the same quality level of detail you see in CLO3D natively made (hand drafted) garments. You simply won't be able to do that. 

   

  My suggestion would be, use the object mesh as a reference and remake it in CLO3D as a drafted set of patterns, and you will then be able to place on all the nice control and physical constraints that come packed inside the 2D to 3D drafting tools. Otherwise you will simply have a single bouncy cloth mesh that will likely perform very rough by contrast to a CLO3D made garment with tailoring and fitting.

  Thank you for your thorough answer. 

  I am new and do not have any experience in 3d digital sewing. The problem I see with recreating the garment(s) in CLO3D is that I need to duplicate extreme detailing like handwork that was done by seamstresses from other eras.

  Is there a way to recreate smocking (not the shirring tool), embroidery, inset lace, piping, crocheted collars and other similar details?

  I hoped there was a way to use a scanned garment since it duplicates with impeccable detail. 

  Would your answer be different if I said I did not need to animate. I just need the garment to fit the avatar; I could live without the garment moving with the avatar. Did I mention that the scanned garment is just a 3D model of a dress on a mannekin- it is not an actual garment.

  Thanks so much! Your help is amazing!
