YuRaNnNzZZ: Added more examples (mostly for copy-pasting purposes)

[[File:PBR_comparison.png|200px|thumb|right|Comparison: left are the base Source Engine shaders, right is the PBR shader.]]

Physically based rendering shader. Source code is available at: https://github.com/thexa4/source-pbr

== Parameters ==
* $basetexture - The albedo texture
* $normaltexture - Sets the normal map (for backwards compatibility)
* $bumpmap - Sets the normal map (new way of setting normalmap)
* $mraotexture - A texture with the metalness on the red channel, roughness on the green channel and ambient occlusion on the blue channel.
* $envmap - Defaults to "env_cubemap", allows you to use a custom one.
* $surfaceprop - One of the following: https://developer.valvesoftware.com/wiki/$surfaceprop
* $model - Should have a value of "1" if the texture is used on a prop.
* $translucent - Setting this to "1" enables alpha blending.
* %keywords - A list of keywords separated by commas, should contain 'empires' as first element. Examples of keywords are: architectural,brown,gray,grime,hanger,industrial,metal,modern,shed,urban,wall,floor
* $basetexturetransform - Looks like this: "center 0.5 0.5 scale 0.1025 0.1025 rotate 0 translate 0 0" for a 2m by 2m texture.
* $alphatest <0|1> - Enables clipping the pixel when the alpha goes below $alphatestreference.
* $alphatestreference <float> -
* $emissiontexture - Allows setting an emission texture. Enabled self illumination.
* $useEnvAmbient <0|1> - Makes it use the lowest mip level of the cubemap for ambient light instead of the ambient cubes. Can cause artifacts with moving props.
* $speculartexture - Enables use of colored F0 (specular map), overrides metalness from MRAO texture

== Examples ==
=== Brush (non-model surfaces) material example ===
"PBR"
{
"$basetexture" "mymod/newtexture_albedo"
"$bumpmap" "mymod/newtexture_normal"
"$mraotexture" "mymod/newtexture_mrao"

"$surfaceprop" "metal"
"$model" "0"
}

=== Model material example ===
"PBR"
{
"$basetexture" "mymod/newtexture_albedo"
"$bumpmap" "mymod/newtexture_normal"
"$mraotexture" "mymod/newtexture_mrao"

"$surfaceprop" "metal"
"$model" "1"
}

=== Model material example with specular map ===
{{Note|Metalness channel is ignored and $basetexture is treated as diffuse.}}
"PBR"
{
"$basetexture" "mymod/newtexture_diffuse"
"$bumpmap" "mymod/newtexture_normal"
"$mraotexture" "mymod/newtexture_mrao"
"$speculartexture" "mymod/newtexture_specular"

"$surfaceprop" "metal"
"$model" "1"
}

== Integrating in your mod ==
The shader is built on top of the [https://github.com/ValveSoftware/source-sdk-2013/ Base SDK github code]. If you continued working on top of that and still use git, you can merge in this change: https://help.github.com/articles/syncing-a-fork/
<br>
You have to start the game with the -forceallmips startup parameter for rough materials to look good.

== Mapping ==
* You have to start hammer with a -game <yourmod> startup parameter. You can add this by editing 'bin/Hammer.bat'
* Make sure cubemaps are on on 128x128 or higher (default in Empires)
* The shader works with the Unreal Engine format of https://gametextures.com

Map:emp crossroads

YuRaNnNzZZ: /* Points of Interest */

{{Sitenav|[[Maps]] > emp_crossroads}}
[[Image:Emp_crossroads_map.png|right]]
==Commander Tactics==
''Chokepoints:'' The middle chokepoint is the critical point on this map. The first infantry rush towards this middle chokepoint usually dictates who will dominate the first half, if not all, of the match.

''Important Note:'' There are many entrances to each base and wise commanders wall off a few entrances to prevent the enemy team sneaking into their base and preventing tanks a direct line of fire on the command vehicle and important structures. It is common strategy to place walls at the side entrances to the main base. Also, it is common strategy to place many missile launching turrets at the front 2 entrances to the respective base and a few machinegun turrets around the base to prevent pesky infantry.

==Squad Level Tactics==
Begin the match by rushing the middle with both engineers and riflemen. Riflemen are to attack any enemy rushing infantry, while engineers construct both machinegun turrets and the 2 refineries at the middle chokepoint. The first five minutes are crucial for who receives not only an added income for research upgrades, but provides a forward base to push back the enemy. If not taken becoming a scout with the hide ability is suggested. This is suggested to be able to climb to the roof of the center building/base and provides excellent view to take out engineers building refineries and turrets. The hide ability plays the important role of not being able to be hit by enemy machinegun turrets.

During the middle phase of this map squads are suggested to use both tanks and APCs in tandem to allow progress to the side of the enemy’s main base. Engineers are used extensively in this process to allow both the repairing of tanks and the building of a barracks on the side of the enemy’s base to allow an all out attack. Suggested squads are made up of both grenadiers and engineers.

During the final phase of this map squads are suggested to be primarily grenadiers due to their anti-tank/turret abilities. If working in tandem a squad of grenadiers can eliminate turrets created by the enemy and provide enough firepower to destroy both the enemy’s barracks and command vehicle.

==Unit and Infantry Tactics==
''Resources are only plentiful on this map if the middle chokepoint is captured.'' Without the middle chokepoint being captured an empire only has access to only 3 refineries. The middle chokepoint provides 2 more refineries which can provide a much needed increase in resources to help provide continued research without a loss in tanks being built.

''Infantry rushing in early is '''highly''' recommended.'' After the initial rush has been completed ramps at all side chokepoints are to be built to prevent early tank rushes. Placing turrets leading up to chokepoints is recommended and can slow enemy advancement considerably.

When artillery is available it is suggested to aim into the walled main base due to buildings being closer together then normal. An artillery shell will almost always give damage to anything if it lands in the main base.

==Points of Interest==
It is important to know at the middle chokepoint there are up to 3 levels with the upper 2 levels being only available to infantry. Also, ramps are available at all side chokepoints, but only can be built on your half of the map. For each main base there are 6 entrances with 2 being on each side except the back wall which is the end of the map.
