Access Surface + Vertex information from LUA

[cocopino]

I am trying to change the vertex information of a model in LUA, I'm trying this code on the model to try and find out which surface I need:

 

require("scripts/class")
local class=CreateClass(...)

function class:CreateObject(model)

       local object=self.super:CreateObject(model)

Print ("model")
Print (CountChildren(model))
Print (model:GetKey("name"))

Print ("ob1")
ob1 = GetChild(model, 1)
Print (CountChildren(ob1))
Print (CountSurfaces(ob1))
Print (ob1:GetKey("name"))

Print ("ob2")
ob2 = GetChild(ob1, 1)
Print (CountChildren(ob2))
Print (ob2:GetKey("name"))

function object:Update()
end

       function object:Free(model)
               self.super:Free()
       end

end

 

The first child is called "U3D_MESH" which sounds pretty promising. It doesn't have any surfaces though, while loading it with GetChild(LoadMesh("mesh.gmf"),1) in BlitzMax does work. When going deeper into the model it's returning bone names.

 

Any ideas? Thanks!
