i need help in creating new figures. i converted an obj file and separated the mesh into separate parts and typed up my own heirachy file. but everytime i go to convert heirachy file, an error comes up saying "cannot read valid wavefront format geom file: 5". i have checked the files name and paths to the geometry resource in the heirachy file, and the individual names of each group in the file itself, but still i get this message. am i missing something to complete this process??
