I don't know if I am doing something wrong here, but I have repeatedly tried to create custom light fixture families and utilize manufacturer-provided IES files for the lighting distribution. I switch the source to Photo-web and then I browse to locate the IES file. I expect to see a the light source object's shape to mimic the lighting distribution, but all I get is a representation that I would expect for a point source. What am I missing here? Do I have to copy the IES files to the folder in the RAC? I would prefer to leave them in an IES folder in our office library.
