[Question] Does it export Skinned Mesh Renderers?

Been using this tool for a while (early 2020 )  and I have a question. 

Is there any way to export models that uses skinned mesh renderer? 

I have been using this tool to create a texture atlas for static scene, but I haven't been able to use it while animated characters. I don't know if this is something that it can't be done at this point, or if is some sort of mistake on my part.
