Lens Flare Shader for Leandwerks

[ParaToxic]

Hei today I had some time to implement a lens flare effect to the engine.

Now it supports Halos, ghost features, chromatic disperation and a lensdirt texture.

I uploaded a video, but I have to say, that the contrast is very low and you can't really see the effect ( let's say not so good ).

 

I have a problem to implement it in the framework, because it needs multiple passes :

-Downsample + Threshold ( the threshold has to be adjusted for the sky brightness )

-Add the Lens flare features

-Blur the Image

-Multiply the resulted image with a lensdirt texture like in BF3 used and blend this with the original rendered image---> Finished

 

I know you can pack some steps together , like the 2nd, 3rd step, but then I need to make 3 passes.

Maybe somebody can tell me how to add that to the framework...

 

Here is the video:

I hope you like it

You might dont have a idea how awfull that sounds - at first glance it makes me think that you copy some shader code from a random game and are trying to add it to your game ... the way they implemented it in there game ... thats quit confusing, not very much legal and aint getting you there.

 

I most likely would use something like the day/night script shader, load the lense textures + a sun flare, draw the sun flare at the sunPos, get a vector from the screen center to the sunflare and draw the lenses depending on that - then fade the lense texture alpha to full alpha ,if looking at the sunflare ... i dont see a reason to filter these flares however, since the god rays will eat them away and the textures used should be good enough in the first place.

Actually, I really like that ParaToxic, it looks very subtle! Can't help you really with the integration into the framework other than using framewerk (where you have the code at your disposal and access to all the buffers). The problem with framewerk is it's not been kept up to data so lacks some of the current features.

First that isn't stolen. There is a realy cool guy, I contact him throug e-mail and asked how he has made this lens flare effect in his video.Then he showed me his idea and I made it similar like he.

 

You can't see it on the video very good because of the contrast and the unoptimized values inside the shaders.But now I'm trying to do it better and the result is better than the video.

I added a first version for the framework to the asset store

very verrrrry niice...

cool. don't make a bf3 lens flare...or at least don't have it take up half the screen like they made theirs to. makes games annoying to play.

Oh jes sry for the error I will change it in a new version.I have the feeling, that nobody get it worked in their Editor ?

Would be cool to hear something about the result, because I can't test it on an other PC

[niv3k]

anymore updates?

[ParaToxic]

Sry not yet, haven't got so much time now....school :/

But I will try to do that when I have some time
