Day and Night Cycle shader

Recommended Posts

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?)! smile.png!!

 

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* wink.png

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.

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
