Assets [WIP]Final Coat - Custom Physically Based Rendering Shader with realtime GI

[Update]
This shader provides an alternative to the built in universal sahder.
Its main function is to provide the full functionality of a IBL pipeline with the support of several new features.

Current state:
- Multiple shader modes (Default, CarPaint with clear coat layer, Anisotrophy, Foliage, Deformable tires, Skin and many more)
- Multiple UV sets for channels (required in some modeling workflows, imported lightmaping etc.)
- Transmissive and Translucent materials (Foliage & Skin)
- Multilayer Detail Splating;
- Blending Decals
- Fully supports the default Lighting pipeline in unity(Reflection probes, Realtime GI, Lightmaping)

Here are some screens with a scene that only uses one shader:



[Update]
So I got the car paint now looking as good as it should, with metalic flakes, flip, candy and perlacent tinting! The variations are endless!



Old Post:
I really liked the IBL approach on everything and I decided to write my own. My shaders were allready half IBL, but they didnt quite compete with true AAA shaders, so I did some research on them and fixed the missing links. Now it looks alot better and I'd like to know what's the communitys opinnion on it?





The shaders overall are heavily optimized, and its actually a single shader, I'm following U5 approach where you have an universal shader and I think that the outcome sofar it's quite cool. On this shader, the original ambient light is disabled. It may look simmilar to marmoset, because I'm using the same reflection texture at the moment. But dont be mistaken, this is a single 6kb shader file.

The file size will grow, because at the moment there is no transparency & box projection support.


Edit.
Latest result:

 

Looking ace! Do you have a build we can see it in?

 

I dont have a build yet, and I'd like to have a build once I get the shaders atleast 50% finished, currently it's too soon for a build

 

I think that the new PBS of unity 5 use a IBL model, i am wrong?

 

Yes it does use an IBL model. But there are things that I do differently. Atleast the beta I tryed, was not the result I wanted. It was good to a specific range and for some reason really hardware hungry.

 

Small update:


The shader currently supports 4 selectable blending modes, Opaque, Cutout, Transparent and Glass.
It also suports AO maps & Illumination maps. Everything except the sky & projector, uses this shader.
Going to add a global reflection manager and Box projection system. I'm going to make this shader as perfect as possible, because I'm goign to use this shader for every 3D project I make.

And ofcourse I'm going to add car paint specific features aswell. But overall I really like the fact that I can now use one single shader for everything.

 

Nice!

Nice ground texture too, in the bluey car pic!

 

Looking good!
Will this shader include normal map, detail map etc?
Also would it be compatible with mobile?

 

Thanks!
This shader allready supports normal maps and I'm adding detail maps aswell yes.

Havent tried its mobile capabilities yet, but I can easly modify the shader to work on mobile. But with mobile there are 2 possible scenarios, I have to limit the shader or the shader would require higher end devices.

Thanks!
The ground texture, if I remember correctly is the same as used in shader forge.

 

More work on the shaders done, Seems like everything goes in the right direction.



shidome_stairs HDR map used in this scene.

 

Wow! Ya better release these. I bought your first pack a long time ago.

 

sorry, but tires look kinda crappy?

 

Thanks, I'm thinking of maybe releasing the shader as a whole system once the features are in and box projection working. Basically when one of my sim demos works with the shaders, then I might release the system if there is a need for it.

No problem, I didnt focus on tires, they basically have ambient only, I can apply the specularity and normals for the next screens. Afterall I'm using this media for testing only. Once the system is finished I can show screens with proper media from my partner. And possibly a demo aswell.

 

Did minor fixes on the shader. Ambient (I think I can call it radiance?) Is now alot better, did some changes to the specular model aswell. As pointed out the tires were crappy, now they should have proper settings. Only thing bothering me visually, is that the reflections seem to need some antialiasing...

 

lookin shiney!

 

Very shiny, polished by the karate kid himself.

 

I think that the shaders IBL feature is finished, everything is now controleld by exposure. And at 0 exposure everything is black. Car paint feature also added.

 

Looking great, is this shader mobile friendly at all?

 

Thanks!
I havent tried it on mobile yet, but in theory it should work on mobile, and if the mobile is highend it should work exactly like on the pictures. I've developed this shader on a laptop that has 4gb of ram and on i3. Right after the box projection is in and user friendly I can compile a playable demo and after that I can do tests on mobile, but mobile is currently not my aim.

 

Looks really good, some tweaking and the scene will be AAA.
Some details to the grass, less reflective road and a detailed background and your game can market itself

 

Thank you!

And this is a picture of the shader in a game environment, everything in this scene is using this shader.


I'm currently using a local cubemap on the car aswell and its a bit dulled to get a slightly "lit up" effect.
Will also try a realtime reflections on the car soon.

 

The environment still need a lot of work but fun to see that it all is coming together *thumb up*

Just make sure in the end to fake the world so that it looks like the cars and the surroundings seem to have the same detail level. Just saying it for safety because some devs tend to love their cars so much that they forget the rest

 

Thats the truth, this is just a plug and play example

And to be honest you dont have to fake the environment, with this shader you just need the correct mapping, will try to do a good example soon.

Also the bigest issue currently for visual fidelity is the reflection mapping. Need to figure out the best way or a combined methdo to get the best baked reflections of a scene, box projection simply would'nt cut the deal for racing games. A global cubemap will basically do the trick in most cases, I'm sure the same method is used in CryEngine3 and Unreal Engine. But I think a road/track surface to reflect properly needs some trickery. Maybe a realtime cubemap with a suitable projection method (but that would be CPU hungry)

 

Heres a bit better image of the shaders in a game environment.
The car has a realtime reflecting cubemap script with RGBM encoding.
99% of this scene uses my single shader. Only the particle material has a seprate shader.

 

Care to share a web player for fun to see it in action?

 

My hands are full of work at the moment so at this time I cant do a web player. But if I get some spare time I can record a video, or maybe upgrade MoDyEn's public demo to use the new shader

Heres another shot in game:


For some reason ingame shots dont look as good as hdri hemispherical light probes found on the net. I suspect it's because the textures are not saved in RGBM. Or they need to be saved correctly... Iwish I had proper media to fully test this new shader.

 

Shader is looking amazing so far, will this be included with MoDyEn Lite or is it a completely separate product?

 

Thanks!
MoDyEn Lite will have simmilar shaders for car parts only (I'll update the old MoDyEn shaders soon and include them with MoDyEn Lite). Visually the only notable difference will be HDR support. But this shader will be a seprate backage and I'm thinking of naming it as MoDyEn IBL. And for a price tag of 80€ should be quite ok. Also am thinking of including these shaders to the pro version of MoDyEn, but pro version is far from finished.

 

Heres a picture of the shaders in agame environment once more, Tho I noticed that the car paint variation needs some tweaking to be fully universal.

 

Nice - Please show a bumped surface.

 

Sorry for a late reply, I totally forgot this thread. Anyway heres a car paint with some normals.

I can add some more later pics to show how the shader works in game. I got rid of some bugs now aswell, so I think its ready to be released

 

I'm trying out shifts track and car with my shaders and oh boy how well it's designed for IBL environment!

 

Did you ever release this @Ravel ? Also, are these screens from a scene using Linear colour space?

 

I didnt have time to finish/release them, and these are in gamma space if I rememer correctly. Once I have more free time, I'll release these.

 

Looks beautiful!

 

Decided to continue on the shaders, since I managed to successfully write some critical effect based shaders for my main package (MoDyEn). Now I turend my shader into a Universal sahder that can be used to replace the unity one. And it contains multiple sub shaders. And it also works 100% with the Unity's Reflection probe system and realtime GI.
Here are some test images:

 

Finally getting the shader together as a fully working unit. Added foliage rendering and UV sets.
And here's a car lit with the shader. The scene is also lit with the same shader!
