As far as the beam radiation is concerned, you can use the
combination of Type67 and Type34 to define the inverse of your
mask:<br><br>
<blockquote type=cite class=cite cite="">
inside
outside<br>

<font color="#FF0000">|</font></blockquote><br>
where Type34 defines the overhang and Type67 defines the inverse of your
real mask. Type67 has outputs for whether the beam radiation is visible
or not. The output BeamFraction is 0 if beam radiation is blocked and 1
if the beam radiation is not blocked. In your case, you will multiply the
unshaded beam radiation by (1-BeamFraction).<br>
You might be able to handle the diffuse radiation in a similar
manner.<br>

I try to model a mask but I don't know how to do: my mask is vertical,
<br>
at the end of an overhang :<br><br>

inside

Does anybody know how to model that ?<br><br>
