I am having a lot of difficulty trying to simply get Unreal to recognize any .hdr or .exr files under the SLS Specified Cubemap selection in the Skylight.
My first question
What exactly is SLS Specified Cubemap?
I assumed it is a traditional 6 image cubemap in either horizontal or cross formation but that doesn’t seem to be the case.
How do you convert any of the HDR images online so that they can be recognized by Unreal when using this setting?
