How to Use SUTransform to correctly render my geometry?

transform

#1

I am working on a code to render skp models directly into Unreal. I am able to render flat models(which do not have hierarchy), but the models which have hierarchies are not rendered correctly.
eg.
Hierarchy Models


In my code I am multiplying the transform to vertices ,

I am updating the finaltransform value from each group/component by multiplying the transform vector for previous group / component!

I want to ask if I am doing wrong? If so, what should I rather do ?
Thanks

Did you notice the geometry helper functions in “geometry.h” ?
