# Softwrap - Dynamics for retopology

That is simply amazing !!
Waiting, waiting, waiting!
Also is it possible to add the ability to align and scale solid meshes (without clothlike deformation)? (probably turn on checkbox)
Will be super handy if you have for example few pieces of geometry (scanned for example)
So you can align them by 3 dots or more

I think rigid alignment is more tricky, I’ve tried looking at a few papers, but there’s all that least squares energy minimization mumbo jumbo that makes my head hurt.

I think I could improvise and hack together a generic algorithm, but it will be deceptively slow.

Well not sure but probably you are digging too deep (or probably I am not objective because I am too far from coding) I think mechanics should be much simpler then now. We have 2 hard anchors (empties) which allows us to pin far parts of the mesh or certain area (they control size and lets say length of the model) and third one control orientation around the axis. So basically 3 pins control just scale and orientation.
Basically this mechanics is already in your addon, you need just in a some way to stop deformation)

My engine is too soft and squishy, I can’t really make stiff simulations with it.

with 3 points its easy, but if you add more points than that it gets really hard, except for scale, which is just calculating an average distance from the center of mass, but for rotation there’s only one way I know to do what you said: computing a transformation matrix from the points and applying this transformation to the object.

Actually 3 points enough to align any two objects. So if it would be great to see this feature if possible. If not then not)) Thank you for your hard work one more time!

Yeah, but I know some people like to add more points thinking it will give more information to the algorithm, I would like that to be the case.

Someone suggested I tried wrapping a human head on a wolf head to do that classic werewolf transformation using shapekeys.

So I gave a try.

Hey guys, I just updated the add-on, Its now available on Blendermarket.

It reminds me “The Company of Wolves (1984)”, i don’t know why.

After installing the latest Softwrap on 2.92 . My blender freezes and not responding every time I exit blender , but file will be saved alright after I hit OK on the dialog box . Anyway If I uninstall the addon from blender , everything turns back fine .
Not sure anyone has experience this or is it just me .
(No specific error message or warning , just a plan windows dialog box that says blender not responding and hit OK to ignore it)

This is strange, I can’t reproduce the issue on my end, so could you help me figure out what’s happening?

Did you install the correct file? Is the add-on running as it should before it freezes?
Does it happen only for a specific model or circumstance or every time?

Could you start blender from the command prompt, so we can see if it leaves any error messages on the CMD window.

If your blender is installed in the default directory, just type: `C:\Program Files\Blender Foundation\Blender 2.91\blender.exe`
and hit enter that blender should run.
Then just make it freeze, hopefully it gives us a clue.
