Can you tell me more about your scene?
- Do you have a post process in your scene set to Unbound?
- If you do, what is the Lens Flare value set to any value 0.1 or higher?
- What is Bloom Intensity set to? Without Bloom there is no lens flare.
- Is this project for Mobile, PC?
- If you setup a Blank PC project and use the default map. Look at the Sun there should be Lens Flare by default. Try this as well and let me know.
Thanks!
Tim
