IES file not working

Many IES files originate from various lighting manufacturers, some of whom put extra text at the beginning of their IES files. If you are experiencing difficulties rendering a particular IES file, try opening the IES file in a text editor and deleting the header text from the top of the file. The file should typically start with TILT=NONE  and if it doesn't, that may be the culprit.
