Complementary Shaders
About:
Complementary is a Minecraft Java Edition shader pack based on Capt Tatsu's "BSL Shaders". The goal of Complementary is being good at everything. Performance, gameplay, beauty, compatibility; you name it. Complementary will try to provide you the most issueless experience possible within the limitations of Optifine's shader pipeline. It runs reasonably fast, supports all GPUs and drivers, works well with mods that no one thought a shader pack could be compatible with, fixes problems that no other shader packs adressed before, doesn't disturb you with excessive effects, and most importantly, it looks good according to the users. If you're wondering about what's changed over BSL, you can check out the complete changelog from BSL to Complementary here: https://justpaste.it/2z91q
Something to note is that this shader isn't installed the exact same way as other shaders. So it's highly recommended that you read the installation.
Installation:
(Note 1: First, don't forget to install Optifine, and unzip the "Complementary_v3.XX_[UNZIP_ME]" file you downloaded from here.)
(Note 2: If you're playing on the latest version and without mods, you can watch this video by DanielPlays instead of reading what's below.)
Path 1: If you are NOT using big mods AND you are playing on 1.13.2 or higher:
1) Select the ComplementaryResources as your resource pack (for many extra effects and fixes)
2) If you want to, you can use a different PBR resource pack instead of ComplementaryResources
3) Select the ComplementaryShaders as your shader pack
Path 2: If you ARE using big mods, OR you're on 1.12.2 or below, OR you just want more fps:
1) Completely ignore the ComplementaryResources
2) Select the ComplementaryShaders as your shader pack
3) Go to Shader Options and click "Profile" on the top right to enable the "Compatibility Mode"

Please delete/ignore the resource pack enable the Compatibility Mode in "Shader Options" -> "Profile" on the top left.
For Help/Updates/Questions/Suggestions: 
This is literally one of the best shader/resource packs I have used and I coupled it with my own improved vanilla textures and my game looks wise is amazing, only down side is it doesn't have the block specific colored lighting like PTGI, and If it does I dont know how to enable it.
Such as light behind a blue glass block is still the normal colored light were as on PTGI if you stood behind a blue glass block the light passing through would turn blue
In reply to blakekevingaming:
Thank you for your kind words, but colored lighting isn't possible without either adding tons of frustrating bugs, or destroying the performance. This is why I won't even consider it.
Kinda wish there's more volumetric light. The volumetric light are only visible under the water but kind of visible on the morning and on early night time. Overall, the shader is good, really love the specular reflection, but have you consider making path traced into this shader?
In reply to huwumo:
Volumetric light of Complementary works like fog (same as how it works in real life). But if you want the other type you can go to Shader Options -> World -> Light Shaft Settings, and change the "Light Shaft Type".
Path tracing in Minecraft is incredibly overrated. It basically blew up because of some YouTubers getting paid to tell some stuff. I'm never going to consider dropping the performance by incredibly many times just to get some buggy colored lighting.
In reply to EminGTR:
Thanks for the help. sorry for the wait, didn't really have the time to comeback to this website
I think i just found a bug, when i increase my light shaft strength to 'Bedrock RTX Level' the sky become as white as heaven and cant see anything in long distance.
But Dang.... , I feel touched for some reason by "I'm never going to consider dropping the performance by incredibly many times just to get some buggy colored lighting"
I appreciate and respect you for the concern about the people that has low specifications computer. *salutes*
In reply to huwumo:
No problem you don't need to be sorry about that.
That "Bedrock RTX Level" light shaft setting is just a joke about how intense their light shafts are :P
About that performance thing, it's not like I'm only concerned about low spec PCs. I'm concerned about pretty much everyone except the top %10 of the people who have extremely powerful GPUs. Minecraft can be very resource intensive especially in older worlds. The current performance of Complementary isn't even enough for the current most popular GPU amongst Steam users (GTX 1060) in a very old 1.16 world with 16 chunks of render distance on 1080p. This is why I believe any less performance than what Complementary currently has is unacceptable.
Anyways thank you for the feedback :P
how did you get the blocks to reflect In the reference images cause mine doesn't?
In reply to chicken991124:
You just need to correctly follow the "Path 1" of the installation. By not forgetting to select ComplementaryResources (or a different "PBR" pack) as your resource pack.
Anyway to enable the Aurora?
In reply to ShadySquid_:
No
Is there any way to make it less bright at night time?
In reply to izcrm:
Brightness slider in Video Settings affects it by a lot. If that' s not enough for you, let me now.
In reply to EminGTR:
It could just be my monitor but is it supossed to be like this with moody settings?

I figured out that i could make the ambient light black to make it darker, so no need to get it darker.
Awsome shader man, keep up the good work!
I don't know what kind of witchcraft you pulled off for the last update, but it runs gloriously. 12 chunk render distance and 100+ fps running 100 mods. I always loved the looks but thought it ran a little heavily in comparison to Sildur's for example, but this is by far the best shaderpack out there in every regard now. Well done!
In reply to chickenmcjesus:
I'm glad to hear that, thank you!
In reply to chickenmcjesus:
Hi, what GPU do you use?
In reply to zevsilio:
GTX1070
In reply to chickenmcjesus:
Thank you
Absolutely beautiful shader! Great for normal gameplay. Amazing work dev!
