55   materials; i.e. translating just the MGF materials does not work.
56   .PP
57   The
58 + .I \-s
59 + option turns on spectral data conversion, producing "spectrum"
60 + modifiers in the output as supported by RADIANCE 6.0 and later.
61 + If you do not plan to employ spectral rendering, then it is
62 + better to have
63 + .I mgf2rad
64 + convert to RGB colors, which is the default.
65 + .PP
66 + The
67   .I \-e
68   option may be used to multiply all the emission values by the
69   given
# Line 69 | Line 80 | and are not generally useful to most users.
80   To translate two MGF files into one RADIANCE materials file and
81   one geometry file:
82   .IP "" .2i
83 < mgf2rad \-m materials.rad building1.mgf building2.mgf > building1+2.rad
83 > mgf2rad -m materials.rad building1.mgf building2.mgf > building1+2.rad
84   .PP
85   To create an octree directly from two MGF files and one RADIANCE
86 < file:

87   .IP "" .2i
88 < oconv '\\!mgf2rad materials.mgf scene.mgf' source.rad > scene.oct
