Ok, sorry for making you go through a step for no reason, but I realized 2 minutes later that I had given you bad info… Sorry for that!
So IES Lighting uses an IES profile to give the light a certain appearance, but it is not an actual texture, you can’t use an image as a Light Profile.
Because of that I can’t help you with your image, but I have Uploaded the entire IES Function Library from Phillips (light bulb maker) that is produced for us to freely use, I think there are around 300 or so total organized into folders that describe a type of light (incandescent, fluorescent, etc). Trouble is there is no way to know what the profile looks like.
So I included an application I use to open up one of these files and look at a preview of what it would do, it works great, but can be a bit tedious…
The other option would be to Import the entire folder into UE4, then you will see a preview of the light profile in the editor.
Either way, up to you how you do it, but hopefully you can find a similar (or even better!!) one than the one you had, and if you want even more of these files I know of a few links, basically any manufacturer of lightbulbs has one of these library’s so they can simulate how it looks for their customers.
Sorry for the long winded post, but here you go:
Dropbox - Error - Simplify your life
Hope is helpful, let me know if you have any issues! Thanks
Would you mind sending us a new link to the dropbox? It’s invalid after these years. Also, does anyone know of a way of creating IES light profiles using meshes as a starting point?
