Is there a way to get shadows from HDR images like a Directional light/Sun?
Maybe there is a way to use a HDR image and not use a sun at all? Or maybe link the HDR image and the sun together some how?
For example, when using Corona in 3Ds Max, you can light the entire scene with a simple HDR image without the use of any other lights. You also get accurate shadows, and by that I don’t mean ambient shadows, but accurate directional shadows.
Is there a way to achieve something similar in Unreal Engine 4?
