Blender | Assign the weight of selected bones only to the mesh?

[Appurushido]

Hello friends,

 

I would like to automatically assign the weights of the leg bones only to the mesh, the others I've weighted manually.

Is it possible to only assign those weights to the mesh?

[Dain Shan]

Yes you can.

Set the skeletton into pose mode

Then select you mesh and switch into Wight paint mode.

(make surde the skeletton and the mesh are on the same layer, or blend the layers together.)

 

Then you can selevt an single bone and can choose the automatic weight, or from envelope weight option from the "weights" menue from the  menuebar at the lower end of the sceen.

Thanks for your answer, Dain.

 

It's working!

But only in Blender.

 

After upload, certain parts of the mesh are not following the avatar movements anymore (it is a little button of a dress in the back neck).

It is moving separately from the rest of the dress.

 

Any ideas?

Have you checked if every part of the mesh is rigged towards the correct bone?

Also have you checked if all vertices have a weight?

You can check this in Blender in the following way:

Select the Mesh. --> switch to edit mode --> set the selection mode to "vertice select" --> make sure nothing is selected --> go to the "Select " menue in the lower menue bar --> from the select menue select "Ungrouped Verts"

Look in the 3D View if vertices are selected (highlighted) now. Those dosent belong to a group then and you have to weight them manually.

 

 Whooohs .. also make sure that all vertice groups are present in the mesh, even if you have groups that dosent have any vertices attached.

Thanks again, Dain.

I did not know about that all vertices have to be assigned a weight.

 

In my particulcar case I have just found out the the subsurf modifier disconnected the button from the rest of the dress.

Weird, no?
Anyway, I connected it again and now weights look ok and everything is moving as it should.

 

Fantastic!
Again, thanks for your valuable input.
