Has anyone got HDR / Bloom to work 'out of the box'?

Hey all,

I'm trying to get the HDR / Bloom effects to work in TGEA 1.7.1 by using the shaders that ship with TGEA. I'm using this TDN article for reference:

http://tdn.garagegames.com/wiki/TorqueShaderEngine/LightingSystem/High_Dynamic_Range_Lighting

However, no matter what I do, I see no changes in the game, and I don't see any properties related to Bloom / HDR showing up for the Sun object in the mission. To test this, I'm using a vanilla, unmodified TGEA 1.7.1 in the Stronghold demo and 'A Stronghold' mission.

Is anyone aware of if this works correctly in TGEA 1.7.1, or if I will instead need to write my own bloom shader and manually apply it to the screen?

Thanks in advance!

Replace your Sun object datablock in /scriptsAndAsserts/data/missions/stronghold.mis:

...
   new Sun() {
      canSaveDynamicFields = "1";
      azimuth = "45";
      elevation = "45";
      color = "0.85 0.85 0.85 1";
      ambient = "0.15 0.15 0.27 1";
      CastsShadows = "1";
         rotation = "1 0 0 0";
         direction = "0.57735 0.57735 -0.57735";
         scale = "1 1 1";
         position = "0 0 0";
   }
   ...

with this:

new sgSun() {
      canSaveDynamicFields = "1";
      Enabled = "1";
      azimuth = "0";
      elevation = "35";
      color = "1 1 0.8 1";
      ambient = "0.4 0.4 0.5 1";
      castsShadows = "1";
      useBloom = "1";
      useToneMapping = "1";
      useDynamicRangeLighting = "1";
      DRLHighDynamicRange = "1";
      DRLTarget = "0.8";
      DRLMax = "1";
      DRLMin = "0.5";
      DRLMultiplier = "1.4";
      bloomCutOff = "1.5";
      bloomAmount = "1.2";
      bloomSeedAmount = "0.5";
         direction = "0 0.954268 -0.298953";
         position = "0 0 0";
         rotation = "1 0 0 0";
         scale = "1 1 1";
   };

Aha! That worked! So I'm guessing there is just a bug in 1.7.1 where it does not give you all the needed properties on the Sun for make it work?

The 'bug' is that the NEW type of sun (sgSun) hasn't been added to the world creator. All this info used to be in the old sun, but no longer...

Ah... well that explains a lot. I love hidden features! ;)
