hi

i'm new to programming with Xfile format, but is there a programmatic way to find out the vertex format of the vertices in an Xfile exported from Maya?

I know of a Mesh.VertexFormat available from direct3d, but it gives 274, meaning {none, texture1, normal} and i assumed it to be CustomVertex.PositionNormalVertex.

However, a part of the XFile shows is as follows

Frame Wall_Front {


FrameTransformMatrix {
25.000000,0.000000,0.000000,0.000000,0.000000,10.000000,0.000000,0.000000,0.000000,0.000000,1.000000,0.000000,0.000000,5.000000,-12.000000,1.000000;;
}

it contains a section called, "FrameTransformMatrix", does this mean it's a Transformed vertex format?

thanks a lot!

i've figured it out after reading online.

turns out that TransformedVertex is very different and I have yet to see it.

my code listing shows exactly PositionNormalTextured vertices. the FrameTransformMatrix is used to transform the mesh from local to world coordinates.
