'''TODO''': Add embedded screenshots and/or gifs/webms for all these effects to show what they look like.

==Particles==

===Create and set the <code>GPU Particle Field</code> level script parameter===

# Open a level
# Launch the editor (<kbd>F1</kbd> key. You may have to hold the <kbd>FN</kbd> and/or <kbd>SHIFT</kbd> key to get this to work)
# Open the Scenegraph properties ('''Windows''' -> '''Scenegraph''' or the <kbd>Y</kbd> key)
# Expand <code>Level</code>
# Expand <code>Script Params</code>
# If you do not see <code>GPU Particle Field</code> in the list, click the '''New parameter''' button
# Double click where it says <code>Untitled parameter</code>
# Type <code>GPU Particle Field</code> and hit <kbd>ENTER</kbd>

Make sure to remove this parameter if you're not using it, or you'll see a bunch of non-moving particles floating throughout the world.

===Set the value of <code>GPU Particle Field</code> to some of these tags===

Separate multiple tags using spaces.

'''Note''': These parameters are '''case sensitive'''. They must be in upper case, or they will not work!

: <code>#ASH</code> - Falling ash, rising smoke, and flying ember particles<br>
: <code>#BUGS</code> - Flying bug particles<br>
:: <code>#MOREBUGS</code> - Increase the amount of bugs (must also define #BUGS to use this)<br>
:: <code>#FIREFLY</code> - Flying glowing bug particles (must also define #BUGS to use this)<br>
::: <code>#WATER_DELETE</code> - Make fireflies not appear under water (must also define #FIREFLY to use this)<br>
: <code>#RAIN</code> - Falling rain particles (see [[RainWeatherEffects|these instructions for how to make this effect more dramatic]])<br>
: <code>#SNOW</code> - Falling snow particles<br>
:: <code>#MED</code> - Decrease the amount of snow particles (must also define #SNOW to use this)<br>

==Weather Effects/World Shaders==

===Create and set the <code>Custom Shader</code> level script parameter===

# Open a level
# Launch the editor (<kbd>F1</kbd> key. You may have to hold the <kbd>FN</kbd> and/or <kbd>SHIFT</kbd> key to get this to work)
# Open the Scenegraph properties ('''Windows''' -> '''Scenegraph''' or the <kbd>Y</kbd> key)
# Expand <code>Level</code>
# Expand <code>Script Params</code>
# If you do not see <code>Custom Shader</code> in the list, click the '''New parameter''' button
# Double click where it says <code>Untitled parameter</code>
# Type <code>Custom Shader</code> and hit <kbd>ENTER</kbd>

===Set the value of <code>Custom Shader</code> to some of these tags===

Separate multiple tags using spaces.

'''Note''': These parameters are '''case sensitive'''. They must be in upper case, or they will not work!

: <code>#ADD_MOON</code> - Adds glowing orb into sky (sky must be dark enough for you to see it, and can be obscured by a "sun" with a visible intensity)<br>
: <code>#ADD_STARS</code> - Adds twinkling dots into sky (sky must be dark enough for you to see them)<br>
: <code>#BEACH</code> - Adds glistening wetness to ground, and water caustics<br>
: <code>#CAVE</code> - Adds a haze effect, similar to what is seen in <code>#MISTY</code>, <code>MISTY2</code>, and <code>SKY_ARK</code><br>
: <code>#DAMP_FOG</code> - Adds full screen rolling effect modifier to fog (must have some fog set in order to see this)<br>
: <code>#DIRECTED_WATER_DECALS</code> - Adds the ability to make the <code>Objects/Decals/water_froth.xml</code> water decal scroll, when modifying its green tint parameter (with <code>CTRL + P</code>)<br>
: <code>#EMISSIVE</code> - Makes the world fully bright (probably not great to keep in level, might be useful for detail work. Not guaranteed to not cause errors)<br>
: <code>#GPU_PARTICLE_FIELD_OCCLUSION</code> - Use alongside Particle Occluder Hotspot if you want snow/rain/other GPU Particle Field weather effects to not appear inside a certain area.<br>
: <code>#LIGHT_AMB</code> - Softens point lights<br>
: <code>#MISTY</code> - Adds a volumetric steamy haze effect (can see it even without fog, but fog makes it more visible, and the effect while there's no fog is not very realistic)<br>
: <code>#MISTY2</code> - Adds a volumetric rolling steamy haze effect (can see it even without fog, but fog makes it more visible, and the effect while there's no fog is not very realistic)<br>
: <code>#RAINY</code> - Makes characters appear wet, and adds a misty animated haze rain effect (see [[RainWeatherEffects|these instructions for how to make this effect more dramatic]])<br>
:: <code>#NO_SKY_HIGHLIGHT</code> - Add this in combination with <code>#RAINY</code> to remove the brightness found in the sky.<br>
: <code>#SCROLL_VERY_SLOW</code> - Uhhh creepy stuff!<br>
: <code>#SKY_ARK</code> - Adds glistening wetness to ground, and adds a volumetric steamy haze effect<br>
: <code>#SNOW_EVERYWHERE</code> - Adds a thin frost cap all over objects, a thick snow cap on the very top of them, and a thin snow cap on characters (most useful if a level is already "snowy")<br>
: <code>#SNOW_EVERYWHERE2</code> - Adds a thick snow cap all over objects, a thin snow cap on characters, and turns the sky into a colorful gradient (can turn a non-snowy level into a snowy one)<br>
: <code>#SNOW_EVERYWHERE3</code> - Adds a thick directional snow cap partially covering objects, and a thin snow cap on characters (can turn a non-snowy level into a snowy one)<br>
: <code>#SWAMP</code> - Adds a slimy coating to everything, and makes rainbows appear<br>
: <code>#SWAMP2</code> - Just like <code>#SWAMP</code>, but it also makes ground and objects above a certain level appear wet<br>
:: <code>#MORE_REFLECT</code> - Makes things shinier/more reflective<br>
: <code>#TEST_CLOUDS_2</code> - Switches the sky box to a moving cloud texture, and projects cloud shadows onto the ground/objects<br>
:: <code>#MORECLOUDS</code> - Increases the density of the clouds (must also define #TEST_CLOUDS_2 to use this)<br>
:: <code>#CLOUDS_DO_NOT_TINT_SKY</code> - Uses the skybox behind the clouds, instead of tinting the sky with a solid color (must also define #TEST_CLOUDS_2 to use this)<br>
:: <code>#CLOUDS_ALPHA</code> - Makes clouds do alpha blending against the sky map, instead of an opaque overlay (must also define #TEST_CLOUDS_2 to use this)<br>
:: <code>#CLOUDS_BELOW_HORIZON</code> - Makes clouds appear below the horizon instead of above it - level is "over the clouds" (must also define #TEST_CLOUDS_2 to use this)<br>
:: <code>#CLOUDS_DO_NOT_CAST_SHADOWS</code> - Gets rid of cloud shadows that are cast on the world - useful if clouds are below horizon (must also define #TEST_CLOUDS_2 to use this)<br>
:: <code>#CLOUDS_VORTEX</code> - Makes the clouds swirl into a point in the center of the level, like the eye of a storm (must also define #TEST_CLOUDS_2 to use this)<br>
: <code>#VOLCANO</code> - Adds a red underglow shader on the world and objects, and adds a heat haze effect<br>
:: <code>#LESS_SHIMMER</code> - Reduces the heat haze effect slightly (must also define #VOLCANO to use this)<br>
:: <code>#LESS_GLOW</code> - Reduces the glow effect slightly (must also define #VOLCANO to use this)<br>
: <code>#WATER_HORIZON</code> - Makes ground and objects above a certain level appear wet, and adds distant fog to make water appear to extend off all the way to the horizon<br>
:: <code>#ALT</code> - Raises the water level, and extends the fog/horizon distance<br>
: <code>#WATERFALL_ARENA</code> - Makes foam texture scroll, adds foggy haze, and makes rainbows appear. Use <code>#CAVE</code> at the same time to remove the rainbows and change the fog a bit<br>
