Hello 
I have some issues to finish the following code. With this I'd like to be able to create meshes from blueprint.
and
I turn arround for hours. I am not verry experimented in c++ and i cannot work with pointers.
This project keeps throwing errors at me. Please help me to fix those. the custom mesh class is the one found in https://github.com/SRombauts/UE4ProceduralMesh and the class here is inspired by the triangle class.
Hope you can fix it
