Hello. This is another lens flare I found on the internet. I've just lightened it up a bit because the original has too warm color IMHO. I hope you like it:



The original is:



Just rename it to ''flare.png'' and copy it to spaceenginedir\data\textures\common\ folder replacing the original.

Its better used with auto exposure ON.

I don't know if that's realistic, I'm not a camera effects pro, so I wouldn't know much about it, but I like it. Thanks.

It's probably not realistic simulating camera lens flare but its closer to the human eye lens IMHO unsure

You're somewhat right. But the primary thing that makes perceived eye lens flares so distinct is not their pattern so much as that they're dynamic, because it's nearly impossible to stay absolutely still; your eyes, head, body, eyelids, are all moving somewhat, and that affects the appearance of the flare. There are other factors too, which make it nigh impossible to simulate a perceived vision lens flare with current real-time gaming graphics. That is one reason why it is more common in many cases for game devs to try to simulate flares from video cameras, for these are much more static and predictable. The only case in a game where I've seen any flares that come close to showing what the eye sees is in Mass Effect 3, where some flares in the environment were dynamic and changed depending on your viewing angle. No doubt this sort of effect will become more common in the future.

I saw a great demonstration and explanation of this very phenomenon, the physics behind it, and realistic ways of rendering human eye lens flares in CG on a web page somewhere, but I can't find the link right now.

How ironic, I actually looked into a normal light and squeeshed my eyes a bit and what I saw was a vertical lense flare o.O

How is that ironic?
