The FALLBACK section is definitely not intended to be required, and in fact is explicitly stated in the spect to be impossible when using TEXMAP NEXT. If FALLBACK being completely optional is unclear in the TEXMAP spec, then the TEXMAP spec should probably be updated. When no fallback geometry is available, the FALLBACK section should not be present, and the untextured version of the TEXMAP geometry should be used instead. I don't think this is stated as a requirement anywhere, but perhaps it should be.
