Can I use UE4 to create a HDR image of the scene? I know F9 is to save the screen, but can I save a 360° HDR image? Thanks in advance!
Create a Scene Capture Cube(Modes tab > All Classes) and place it in the middle of your level. Then create a Render Target Cube in the content browser and use it as the texture of scene capture. Finally right click on the render target cube > Create Static Texture and there you have it. Now you can export it or use it in a skylight or a pp volume as an HDR image.
Brilliant!
