====== Level Settings window ======
This window holds settings for the level, such as global fog and skybox.

==== Skybox settings ====

{{ :hpl3:tools:maineditors:level_editor:window_levelsettings_skybox.png?nolink&300 |}}

  * **Active**: will enable or disable the skybox.
  * **Color**: if no texture is set, the skybox will use a flat color defined here.
  * **Texture**: loads a cubemap texture to be used as skybox.


==== Global Fog settings ====

{{ :hpl3:tools:maineditors:level_editor:window_levelsettings_fog.png?nolink&300 |}}

  * **Active**: enables or disables the global fog.
  * **Culling**: sets if the fog should cull objects that are behind the 'End' distance.
  * **Start**: sets the distance to the camera where the color fading should start.
  * **End**: sets the distance to the camera where the color fading should be fully done.
  * **Falloff Exp**: sets the attenuation factor that will be used for the fading.
  * **Color**: color for the fog.


==== Decals ====

{{ :hpl3:tools:maineditors:level_editor:window_levelsettings_decals.png?nolink&300 |}}

  * **Global Max Triangles Per Decal**: this here will set how many triangles decal meshes will have unless individually tweaked.
  * **Reset Created Decals**: this will reset all created decals to use the above value.

==== Directional light ====

{{ :hpl3:tools:maineditors:level_editor:window_levelsettings_directionallight.png?nolink&300 |}}

  * **Active**: will toggle the directional light for the level.
  * **Direction**: 3D vector indicating where the light will point at.
    * **Get from camera**: copies the direction from the viewport camera.
  * **Diffuse**: the diffuse color for the light.
  * **Sky color**: objects will reflect shades of this color on their upper side.
  * **Ground color**: objects will reflect shades of this color on their lower side.
  * **Brightness**: brightness for the light.
  * **Cast shadows**: if the light should cast shadows.
  * **Shadow map bias mul**: tweak to move the shadow away from the light to remove shadow banding and artifacts.
  * **Shadow map slope scale bias mul**: tweak to move triangles even further away from the light if the angle to the light is steep.
  * **Shadow caster distance**: sets how far our light source will be when it comes to casting shadows. Increase to remove artifacts caused by shadows. A too high of a number will make shadows start to disappear.

==== Env Particles ====

The inputs in this tab control the parameters for the environment particles in the level. 

{{ :hpl3:tools:maineditors:level_editor:window_levelsettings_EnvParticles.png?nolink&300 |}}

  * **Active**: will toggle the environmental particles.
  * **Color**: the particles will be tinted with this color.
  * **Brightness**: how bright the above color will show.
  * Rest of parameters are explained in depth [[hpl3:engine:rendering#Environment Particles|here]].
==== PostEffects ====

{{ :hpl3:tools:maineditors:level_editor:window_levelsettings_PostEffects.png?nolink&300 |}}

=== ToneMapping ===
  * **MiddleGrey**: A real value that sets what should be considered the middle grey value.
  * **Exposure**: The total light that is allowed through the camera, increasing this value makes the image brighter. In the range of -10 to +10.
  * **WhitePoint**: A real value that sets which value that should be considered the brightest.

=== ColorGrading ===
  * **Color Grading texture**: 3D dds texture file defining the color grading map.
