FChannelTextureRenderer

FMegaMeshChannelCollection contains functions and objects needed to build the rendering elements representing the masks and channels for the sections of the mega mesh Each base is assigned an Id in the collection allowing to reference and access other resources associated with it such as individual textures stored in the Texture collection
