Skinning Editor doesn’t have that functionality. Is it a functionality that you would like to use?

I want to create vertices at some certain positions , but now I just can use mouse to place them so I cant achieve this goal . Is this possible to do it via script? like create a vertex in position (1,1,0)??

Just to be sure, since you’re working in the Skinning Editor, is it for animation? Are you trying to create a custom shape? Or the auto-generated vertices are not aligned the way you want?
We currently don’t have Skinning Editor APIs that would allow you to set a custom outline in code.

If it’s the custom sprite outline that you are after, there is an API that you could use.

I want to create a character not an outline ,but size of the sprite is 8*8 ,( because of optimization)
so I want to create lots of vertices and bones inside this sprite,
but because of its size , I cant place vertices exactly at the positions I want cause I have to use mouse

I want to understand your particular use case better. What type of character are you creating? Have you tried auto-generating vertices with the Auto Geometry tool? Are they not aligned the way you need?

sorry I couldn’t tell you exactly what I want :slight_smile: .I wrote this ,it creates some vertices and edges on the first pixel ,now my only problem is creating bones , Can you show me an example ?
