Rfluxmtx with 2305 sky subdivisions

1

Hello again radiance community!

I’m trying to generate a DC matrix for a sky with 2305 subdivisions (i.e. in gendaymtx I used -m 4).
I’ve successfully done it for a typical 146 sky, but now when I run
rfluxmtx -I+ -y 28905 -lw 0.0001 -ab 1 -ad 10000 -n 90 -faf h=r4 - sky/skyglow.rad -i oct/Stadium.oct < pts/LevelPitch_v.pts > matrices/DC_m4.mtx
I get

rfluxmtx: -i, -I supported for pass-through only
make: *** [Makefile:78: flux] Error 1

All I did was add “h=r4” to the line, but clearly I’m going wrong. Any fixes???

Thanks!
Joe

Hi @jroberts,

You have to change the hemisphere subdivision in the receiver file, skyglow.rad, and not in the command line.

You should have something like this in your receiver file.

#@rfluxmtx h=r4 u=Y
void glow sky_glow

4 1.000 1.000 1.000 0
