PBR Shader

This plugin adds a true PBR shader to SFM. No more hacky, manual setups with multiple layers of materials are needed!

Based on the PBR shader made by the Zombie Master: Reborn[github.com] team.

PBR is a rendering method that simulates the physical behavior of light in the real world. Different materials like metal, wood, etc react consistently to the environment under a PBR setup. This is the most standard setup for materials in modern game engines.

This PBR shader supports albedo, MRAO (metalness, roughness, ambient occlusion), emission, specular and parallax mapping textures.

Make sure you have installed Plugin Loader and ran its patch script once.
(Scripts > ficool2 > Plugin Loader)

You also need to make sure you are subscribed to Shader Loader.
This plugin should automatically work when you download it in SFM, and then restart.

You can use the example model to see if you installed PBR correctly: https://exit.yueirsjskjl.cf/sharedfiles/filedetails/?id=3671444926

The shader name is PBR. The shader supports both models and brushes, and has the following parameters:

$basetexture - Albedo map
$bumpmap - Normal map
$mraotexture - Texture with metalness in R, roughness in G, ambient occlusion in B. Will default to the default texture dev/pbr_mraotexture if none is provided
$emissiontexture - Emissive texture; is a color texture, not a mask
$speculartexture - Specular F0 RGB map, overrides metalness from the MRAO texture

$model (0/1) - Whether the material is on a model or not. You must set this to 1 on models!

$metalnessFactor - Metalness factor. Default is 1
$roughnessFactor - Roughness factor. Default is 1
$aofactor - Ambient occlusion factor. Default is 1
$ssaofactor - SFM's SSAO factor. Default is 1

$Parallax (0/1) - Use Parallax Occlusion Mapping
$ParallaxDepth - Depth of the Parallax Map
$ParallaxCenter - Center depth of the Parallax Map

$color - Albedo tint ($color2 is not used here)

$alphatest (0/1) - Enables binary transparency
$alphatestreference - Specifies the minimum color value of the alpha channel in which the transparency is rounded to opaque. A value of ".3" will create a thicker shape while a value of ".7" will create a thinner shape

If you are uploading an model on the workshop that uses this shader, please add this addon as a dependency, as the PBR shader will not work without this plugin installed.
You can do this by going into Add/Remove Required Items on the page and adding this plugin in the list.

PBR models do not render in HLMV (yet).
