Day and Night Cycle shader

[shadmar]

Wasn't sure where to put this since I can't get it to work in the workshop since it needs a big controlscript.

 

 

Anyway here it is :

 

General

• Preetham skymodel is used (look up on wikipedia)
  
• UnCharted2 tonemap
  
• Procedural stars at night
  
• Procedural Clouds.
  
• Alot of adjustables
  

Install

• Download at bottom of page here
  
• Unzip straight into the projects root folder
  

Use

• Drag the Sun prefab from the prefab folder
  
• You can adjust all sorts of stuff in the script tab of the Sun object
  
• It will adjust to the rotation of the Sun (which is a directionallight) when you run (F5/6)
  
• Works very well with bloomsettings : luminance=0.11 midgray=0.158 whitecutoff=0.298
  
• Added one small example map as well in the maps folder.
  

Update :

• Fixed the ATI issue, thanks TattieBoJangle
  
• Fixed the cloudscale issue, thanks HaydenMango
  
• Skydome now follows the camera (if found)
  
• Skydome resizes to the camera's drawdistance (if found)
  
• Added adjustable bloom settings (if workshop the bloom is added the scene)
  

Edit: soon inthe workshop.

Really great job, shad (and, klepto too, i think?)! !!

 

There's still room for improvement, but what you have already done, is really awesome!!

 

Some godrays coming through the clouds would really be great! *HINT* *HINT*

[Josh]

That is so incredibly cool.

[cassius]

Suprb, thanks.

 

How can I make the day last longer?

[macklebee]

How can I make the day last longer?

marry a woman that nags?

 

great work shadmar.

[cassius]

I would rather marry a woman who made the nights longer.It takes longer to do everything when you are old.

[shadmar]

LOL!!

 

[cassius]

Thanks

[cassius]

If I want a certain event to occur only after dark in my game,is there a way I can tell my game it is nighttime?

[shadmar]

from c++ or lua ?

[ChrisV]

from c++ or lua ?

Both would be equally usefull. Thanks!

[cassius]

from c++ for me.

[shadmar]

Well, either way (havent tested), but in theory you can:

 

1. store your world objects in an array or list when loaded from the map : http://www.leadwerks.com/werkspace/topic/6386-c-finding-entities-in-a-scene/page__hl__map or http://www.leadwerks.com/werkspace/topic/6887-communicating-from-lua-to-c/

 

2. check if entity->GetClassName=="DirectionalLight" && entity->GetColor().x <=0 then it's night.

I finally got around to adding this to my project. It looks sooo amazing. You are the best Shadmar thank you!!!

 

Here is a little preview of what it looks like in game. It is speed up to be 5 times faster so the video wouldn't be super long.

Tip for adding fast bloom (good looking) to the sky:

 

1. Add bloom from the workshop to your scene tab : http://steamcommunity.com/sharedfiles/filedetails/?id=256268930&searchtext=

2. Add a pivot to your map and connect this bloom control script :

 

function Script:UpdateWorld()

if self.camera==nil then

local world=World:GetCurrent()

for i=0,world:CountEntities()-1 do

if world:GetEntity(i):GetClass()==Object.CameraClass then

self.camera=world:GetEntity(i)

tolua.cast(self.camera,"Camera")

System:Print(world:GetEntity(i):GetClassName())

break

end

end

else

self.camera:SetKeyValue("bloom_Luminance","0.11")

self.camera:SetKeyValue("bloom_MiddleGray","0.158")

self.camera:SetKeyValue("bloom_WhiteCutoff","0.298")

end

end

 

Edit: Correction, WhiteCutoff 0.298

[Haydenmango]

Hey shad just wanted to ask if

self.shader:SetFloat("cloudscale",self.cloudheight) -- lesser is bigger

is supposed to be

self.shader:SetFloat("cloudscale",self.cloudscale) -- lesser is bigger

in the UpdateWorld() function.

[shadmar]

Ah yes that would be correct. Thanks!

[TattieBoJangle]

Looks GREAT! I get Failed to compile fragment shader any ideas?

 

 

Fragment shader failed to compile with the following errors:

ERROR: 0:317: error(#160) Cannot convert from: "3-component vector of vec3" to: "highp float"

ERROR: error(#273) 1 compilation errors. No code generated

Failed to compile fragment shader.

Error: Failed to compile fragment shader.

[shadmar]

Do you run of an intel integrated card?, they often complains when vecs are converted.

 

Anyhow change line 317 to :

 

float cmix=cloud.x*cloudmix;

[TattieBoJangle]

Hi Shadmar no it the ATI R9280x Platinum but i will try that and get back to you

[TattieBoJangle]

where do i change float cmix=cloud.x*cloudmix; as there is only 63 lines in the lua

[shadmar]

daynight.shader file.

[TattieBoJangle]

Just the same error message shadmar if i changed it right lol this is a video of what i get when adding it

[cassius]

Before using this shader I got rid o my existing skybox and directional light.Was that the correct thing to do?

[TattieBoJangle]

Got it working many thanks
