HQ Bloom and Lens Dirt, Physically Based Shading and Light Attenuation WIP

Hey, guys. I just wanted to share some screenshots of things I have been working on regarding graphics in Unity. I'm not satisfied with the way Unity calculates most of its lighting by default, but since Unity is so very easy to modify in this regard, I've been having a lot of fun doing so!

Firstly, I've been working on a bloom/lens effects shader. It's a simple post process effect that simulates the airy disk (http://en.wikipedia.org/wiki/Airy_disk) of a camera lens. It correctly does not use threshold, and is energy-conserving. It also has a texture input that is used as a "lens dirt" effect. The texture adjusts scattering of light on the lens, but again, obeys conservation of energy to eliminate false highlights. The texture itself is something I whipped up just as a test.



These bright objecs are just simple emissive objects. Also, I'm using a custom tonemapping algorithm with a slightly more exaggerated toe and shoulder. You can also see very subtle screen-space reflections (on the left side of the cube).



I'd also like to show some comparisons of Unity's built-in light attenuation and shaders vs my physically correct light attenuation and physically based shaders. The specular highlights are energy-conserving and also exhibit the fresnel effect for more true-to-life highlights. Light attenuation is calculated based on how light attenuates in real-life instead of Unity's falloff. I decided to use a wet concrete material to show off the effects.

 

Cool!

 

Just one word : Amazing

 

amazing does it eat up framerate by any chance?

 

from what I've seen so far - he's getting around 350fps in those scenes and no, not on a Titan

 

What necromancy is this!? Superb.

 

Wooooo!!!

 

Very impressive. I'll be following this

 

JJ Abrams would be proud

 

lol

 

Please tell me you're planning on putting this on the asset store.

 

Performance is very good so far on my system. I'm running a GTX 560 TI and getting ~300 fps in these scenes (of course, they're quite simple). The bloom/dirty lens effect only takes about the cost of running two stacked default Unity bloom shaders, which is what I had been using previously to try to get a nice looking bloom (sometimes it would take three or four). The light attenuation and physically based shading probably isn't even worth measuring since it's basically already using available systems, just slightly differently. Of course, I am not aiming these effects for mobile, so no word on that.

Just another shot here with a dry concrete material applied instead.


Here's an example of the dynamic range capable with this effect. Objects that are not many times brighter than the surrounding objects will not cause false bloom. So, you can go JJ Abrams style if you'd like, but you're not bound to it.

 

Once again, looks great. Would love to be able to use these myself.
Is it just a custom shader + bloom + tonemapping, or are there other stuff thrown in as well? Is the reflection mentioned in the OP part of the shader, or is it something else? I'm also curious: why does stacking default bloom effects have a better look?

 

Love it, can't wait to see more of it. Or use it in my own projects, for that matter.

 

Hey guys, for those of you who are interested in this effect, I've just uploaded a live demo I put together in this thread here: http://forum.unity3d.com/threads/241440-Natural-Bloom-and-Dirty-Lens-Live-Demo?p=1599231#post1599231

 

God, this is amazing.
Are you a wizard by any chance?

 

INSANE... Love it... I wonder if these lights will work with Alloy... It looks INSANELY real

 

this looks gorgeous. Really love the lighting.

 

Stunning is not even the right word for this

Is this coming to the asset store or is for internal use only ? It would be an instant buy if it did for sure.

Amazing work

 

good news - it will be on the asset store and soon too

 

and....sonicEther....are you the wizard from minecraft???

 

, that is some even more stunning news

Will this require Unity pro btw ? I use Unity free for now, but would buy it anyway since i do plan to get Pro, hopefully soon

 

yes ... yes, he is

 

yeah, it does - it's an image effect

BTW Unity really needed some high quality PostFX since the embedded ones are from another time. You look like someone who can bring a lot of awesomeness to Unity (and a lot of money for you since many people like me are fighting with embedded PostFX and are ready to spend money in high quality PostFX)

I would be really happy to be one of your first customers for our game "Edge Of Eternity"

Good luck !

 

This is some amazing PostFX work and the physically based lighting is just eye candy.

 

Jaw, meet floor.

 

Hey guys, thanks for the comments! To answer those wondering if I am putting this on the Asset Store I've decided that, yes, I will be submitting this to the Asset Store. I want to get a general opinion on what would be a fair price, however.

More information is in this thread here: http://forum.unity3d.com/threads/241440-Natural-Bloom-and-Dirty-Lens-Live-Demo?p=1599231#post1599231

Please post there and give me your opinion on what you'd be willing to pay. More information on what is included is also in the thread I've linked above.

 

@sonicether: I have to say... nothing! It is simply too amazing for words.

All I can say is, this is the AMAZING minecraft mod enhanced to infinity, and ported to unity!

 

This is incredible! This is definitely going on one of my projects, in the future!

 

@FBTH: I am guessing you don't have pro, do you?
Don't worry, this one's in the same boat!

 

@FuzzyQuills Lol yup xD

So from that, I'm guessing this is already inside of Unity pro? Or this is pro only?

 

@FTBH: This would be a Unity pro package, judging by framerate and visual quality. no indie solution, not even my own, could manage this...

 

@FuzzyQuills Looks like I'm getting pro!!

 

Good luck!

 

Is the wet/dry concrete shader made with GLSL or HLSL, i would really like to know. Keep up the good work. @sonicether

 

I'd imagine it would be HLSL, as practically everything in unity uses a modified HLSL compiler toolchain.

GLSL can be used though, would be interesting if @sonicether did that, I've often considered trying GLSL for mobile android games...
