I am trying to merge two different types of buffer geometries: one
BoxBufferGeometry and two
ExtrudeBufferGeometry - for this I am using
Unfortunately I am getting following error message:
mergeBufferGeometries() failed with geometry at index 1. All geometries must have compatible attributes; make sure index attribute exists among all geometries, or in none of them.
Here I understand that my Extrude Geometries are not getting any indexes - how can I come around this issue?
Many thanks for your help.
