Hello, I am attempting to model some fixtures by a manufacturer using their IES files and finding that the light output in FQRW is highly unrealistic. Fixtures don't read at all until I manually set the lumen output to north of 2500 lumens (the environment being a very small office). The IES contained within has a lumen value of 261, which should read fine in a small environment. I currently have the Emitter in Lighting Options set to around 1,400% based on another thread I looked at, but am hoping there is a way to get more lumen-realistic output with these fixtures set at 100% so that I can provide the manufacturer with renders that even somewhat realistically reflect the actual light output of his fixtures. Any thoughts on how I can work these spotlight fixtures to create renders that are accurate to the actual details of the fixture/IES file and not just dialed in by eye? The biggest reason for this is that the manufacturer and I work remotely from each other and I don't always have the chance to use his new products in real life to get a visual sense of how bright they are in space and would love to rely on the data in the IES. Thank You! Office.vwx
Custom IES lights should show the .IES lighting distribution in OpenGL. Currently in Vw2016 SP2, Custom Lights with an IES distribution file do not show any light pattern and therefore do not render as light sources. See this thread for additional information.
I'm in the process of learning how IES files work and am wondering if anyone has a good resource for a library I could play around with? Something like so would be great (looking for the reference jpg and the corresponding .ies files):
