It's an ies called "nice.ies" If you do an search on the net, you'll find it.

I found it, both on the web and inside Maximus3D huge collection of ies files, but I get a rendertime error saying "Photometric file not found". Other files in Maximus3D collection are working fine.
Is maxwell expecting a particular format for ies files?

Should work fine, I uploaded the one I was using:

Try changing the location of that IES file perhaps.

Thank you Mihai, your file is working fine.

I had a look at the differences between your file (working), and the one I had found before (not working): the content is the same, only the formatting is a bit different:

Your file:
IESNA91
[TEST] Test unknown
[MANUFAC] Manufacturing company unknown
TILT=NONE
1 13172.61 1 37 1 1 2 0 0 0
1 1 0
0.00...

The file giving an error:
IESNA91
[TEST] Test unknown
[MANUFAC] Manufacturing company unknown
TILT=NONE
1 13172.61 1
37 1
1
2
0 0 0
1 1 0
0.00...

Removing the extra carriage returns cures the problem.

Cool Thanks for comparing.....interesting.

Hi all,

the IESNA format specifies that following the line with keyword TILT=NONE, there is a SINGLE line with ten (10) numbers, which correspond to:
1.- Number of lamps
2.- Lumens
3.- Multiplier
4.- # of V angles
5.- # of H angles
6.- Goniometry type
7.- Units (m or ft)
8.- Luminaire Width
9.- Luminaire Length
10.- Luminaire Height

Obviously, the file with that line split into several ones will fail to be read.
Hope this clarifies this issue a bit.
Thanks a lot for reporting.

Best wishes,
M.
