IES light profiles

- [Voiceover] Lets take a look at IES light profiles.…IES light profiles allow you to take real world data…of the physical distribution of a particular light…and apply it to a point or spotlight in Unreal…to give it that extra bit of realism.…IES stands for illumination engineering society.…Among other places you can download IES light profiles…from the Philips lighting website.…If you scroll down you can see there's…different categories of lights…and if I click on one of those, "Halogen" for example.…

You can see a list of all of their products…and their corresponding IES light profile data file.…If I click on one of these it's actually going to…show the guts of the file.…It's all a bunch of numbers,…we don't really have to concern our self with that.…What I really want to do is right-click,…"save link as", and I can save that to a local directory.…I've actually gone ahead and downloaded a bunch of them.…So if you go back into Unreal,…you're gonna scroll over to the courtyard area,…and create a point light.…
