Mirror weights causes Unspecified failure

[Szabolcs Matefy]

Hey folks,

 

I want to mirror skinning from a portion of the mesh to the opposite side. However, after the Create symmetry template dialog box (and prior creating the symmetry map itself) the operation cancels saying that unspecified error occurred…

 

This is the code part where it fails (enveloping.vbs)

 

function get_deformers               (in_obj, out_deformers )

 

                dim deformers, myenv, weights, i

 

                set deformers = CreateObject("XSI.Collection")

                set myenv = in_obj.activeprimitive.constructionhistory.find("envelopop")

                Weights = myenv.Weights.Array

 

                weights = myenv.Weights.Array

 

                For i = lbound(weights ,1) to ubound(weights ,1)

'                               87892:   The fact that we didn't mirror effectors caused scenes that have envelope weighting on effectors not to symmetrize correctly.

'                                                               Enabling symmetry on effectors.

'                               if( myenv.deformers(i).type <> "eff" ) then

                                                deformers.add myenv.deformers(i)  ß------------------------------------------------------------------------ Line of failure is this

'                               End if

                next

 

                set out_deformers = deformers

 

end function

 

At first glance what hit my eyes is that once deformers is a collection, and then deformers is a property of the myenv object. Can it cause an issue? I can’t do any edit, since the folder is read only, and our admin doesn’t let me play with the rights in my Softimage folder…

 

 

Cheers

I wouldnt edit that code even if you could.

This has happened to me before, and it was related to a corrupted piece of geometry.  That asset may have been created in a previous version of XSI, who knows. 

Our methods here at very cavalier, as every modeller/TD has their own techniques, so its quite common for geometry to get corrupted somewhere in the process.  Once it happens, usually envelope operations will stop working properly.

Basically, I just export out as OBJ, reimport, Gator everything across, and its fixed.

best of luck,

I'm not sure if it is related, but Create symmetry template gets you an error if your enveloped model weights aren't normalized and the sum of the weights per point isn't 100.

It usually happens when you import FBX, the weights aren't normalized and the weights sum about 99.9 or 100.001, but SI doesn't flag them.

You can normalize your weights by selecting your points, check normalize in your weight editor and Add 0 weight to any deformer.

I resolved meanwhile. For some reason, the number of deformers were double of the number of real deformers…Envelope saved, reenveloped, envelope loaded, and now just fine
