IES File Manipulation

Will this work with feet? My IES file looks like this... Note that the
IES file was converted in feet with a .81 light loss factor, then the
lboxcorr dimensions are in meters, and then my genbox is in feet again.
(Note the insertion point is the top of the fixture at 0,0,0).

The fixture looks right.. the distribution is no longer shadowing
itself, so it looks right....

Sound good?

Hiya Mark,

Do you have the Rendering with Radiance book? there's a detailed
example of using lboxcorr to create a rectangular shaped illum

container

for your IES distro. I think that's what you need. (?)
