<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m running a three phase method analysis and am running into some funny behaviour. I generated windows using Honeybee msh2rad, converting a Rhino mesh to a radiance geometry file via TurtlePyMesh & obj2rad.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I generate my view matrix, it works fine for some windows, but not for others – and there’s no clear difference in geometry between those that work and those that don’t work. My command is:<o:p></o:p></p>
<p class="MsoNormal"> Rfluxmtx –ab 4 –ad 5000 –y 81 < ChEast.pts – windows_pts/window_04.rad material.rad ChEast.rad > viewpts_04.mtx
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And the error I get is:<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:36.0pt">rcontrib: fatal - duplicate modifer 'M-nor'<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My daylight and sky matrices work for fine for all of the windows, so I don’t know what it is. Any idea what can cause this kind of behaviour? Does rfluxmtx need perfectly flat / regularly shaped objects?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
