Caligari87: Added categories because I'm tired of not being able to find this page

Make sure to save any changes to your level before adding these, because typing them in is a bit fragile right now.

Be careful when adding these to not type in <code>#</code> with no text behind it, or you will get a ton of OpenGL errors, and and probably crash to desktop.

The trick I use is to type the word first (such as <code>ASH</code>), then add the <code>#</code> at the beginning of the word (so it becomes <code>#ASH</code>).

Another trick is to type these tags manually into the Scenegraph Search field below, where they do no harm. Then copy and paste it up into the script parameters above.

==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. Remember to either copy in the whole tag, or type in the name before adding the preceding <code>#</code>, or you will likely see a lot of errors, and may crash the editor.

: <code>#ASH</code> - Falling ash, rising smoke, and flying ember particles 
: <code>#BUGS</code> - Flying bug particles 
:: <code>#MOREBUGS</code> - Increase the amount of bugs (must also define #BUGS to use this) 
:: <code>#FIREFLY</code> - Flying glowing bug particles (must also define #BUGS to use this) 
::: <code>#WATER_DELETE</code> - Make fireflies not appear under water (must also define #FIREFLY to use this) 
: <code>#RAIN</code> - Falling rain particles 
: <code>#SNOW</code> - Falling snow particles 
:: <code>#MED</code> - Decrease the amount of snow particles (must also define #SNOW to use this) 

==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. Remember to either copy in the whole tag, or type in the name before adding the preceding <code>#</code>, or you will likely see a lot of errors, and may crash the editor.

: <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) 
: <code>#ADD_STARS</code> - Adds twinkling dots into sky (sky must be dark enough for you to see them) 
: <code>#BEACH</code> - Adds glistening wetness to ground, and water caustics 
: <code>#DAMP_FOG</code> - Adds full screen rolling effect modifier to fog (must have some fog set in order to see this) 
: <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>) 
: <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) 
: <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) 
: <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) 
: <code>#RAINY</code> - Makes characters appear wet, and adds a misty animated haze rain effect 
: <code>#SCROLL_VERY_SLOW</code> - Uhhh creepy stuff! 
: <code>#SKY_ARK</code> - Adds glistening wetness to ground, and adds a volumetric steamy haze effect 
: <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") 
: <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) 
: <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) 
: <code>#SWAMP</code> - Adds a slimy coating to everything, and makes rainbows appear 
: <code>#TEST_CLOUDS_2</code> - Switches the sky box to a moving cloud texture, and projects cloud shadows onto the ground/objects 
: <code>#VOLCANO</code> - Adds a red underglow shader on the world and objects, and adds a heat haze effect 
:: <code>#LESS_SHIMMER</code> - Reduces the heat haze effect slightly (must also define #VOLCANO to use this) 
: <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 
:: <code>#ALT</code> - Raises the water level, and extends the fog/horizon distance 
: <code>#WATERFALL_ARENA</code> - Makes foam texture scroll, adds foggy haze, and makes rainbows appear
