[Radiance-general] Re: obj2rad failing

[Greg Ward]

Hi Erwin,

Importing minus the vertex and textures can be done with this command:

	sed '/^f /s@/[0-9/]*@@g' Hauk-EZ.obj | obj2rad > Hauk-EZ.rad

Seems to work for me, at least.

P.S.  I also tried putting all the vertex normals at the front of the  
file, thinking maybe ACAD just scattered them throughout in violation  
of one of the Wavefront syntax restrictions, but there were still  
faces that referred to vertex normal indices that exceeded the total  
number of vertex normals in the file.
