Hello, I use autodesk maya and I export fbx models without triangulating. I will need index buffer to display them correctly. I use assimp for C#. When I try to get indices I get something like 0,1,2,3,4,5,6.. I try to get them like "mesh.GetIndices();" it returns i"nt []" an array whih contains incorrect positions 0,1,2,3,4,5,6,... This means there is no index data for index buffer inside FBX or I can not access it correcty ?
