# BSDF material - type missing (OCONV)

#1

Dear all,

I am trying to you a BSDF material in a regular rtrace simulation. When I try to use oconv I get the following error:

I am using Radiance version 5.0.a.12 (installed from NREL installer) and my rtrace is version 4.1a.

this is how I defined the window:

void BSDF windowglassBsdf
6 0 …/Radiance/data/McNEILtut_singleClr.xml 0 0 1 .
0
0

windowglassBsdf polygon window
0
0
12 0.5 -.15 1
0.5 -.15 2
3.5 -.15 2
3.5 -.15 1

Any thoughts?

Kind regards,

Samuel

If you are on a Windows machine, it might be that the rtrace being found through the PATH is from Daysim and not the NREL version. The `where` command will tell you which rtrace is being called.

If you re-arrange the order of the paths such that the latest NREL installation path is before all the other Radiance installation paths, I think it should work out.

You can also set the path manually before typing in any Radiance commands (this will work for batch files too):
