Material

IMaterial, number Material( string materialName, string pngParameters = "nil" )

Description

Either returns the material with the given name, or loads the material interpreting the first argument as the path.

When using .png or .jpg textures, try to make their sizes Power Of 2 (1, 2, 4, 8, 16, 32, 64, etc). While images are no longer scaled to Power of 2 sizes since February 2019, it is a good practice for things like icons, etc.

Arguments

1 string materialName
The material name or path. The path is relative to the materials/ folder. You do not need to add materials/ to your path.

To retrieve a Lua material created with CreateMaterial, just prepend a "!" to the material name.

Since paths are relative to the materials folder, resource paths like ../data/MyImage.jpg will work since ".." translates to moving up a parent directory in the file tree.
2 string pngParameters = "nil"
A string containing space separated keywords which will be used to add material parameters.

See Material Parameters for more information.

This feature only works when importing .png or .jpeg image files

Returns

1 IMaterial
Generated material
2 number
How long it took for the function to run

Example

Creates a PNG material with noclamp and smooth parameters set and then draws on screen.

In this example the .png file is located in materials/vgui/wave.png

local wave = Material( "vgui/wave.png", "noclamp smooth" ) hook.Add( "HUDPaint", "HUDPaint_DrawATexturedBox", function() surface.SetMaterial( wave ) surface.SetDrawColor( 255, 255, 255, 255 ) surface.DrawTexturedRect( 50, 50, 128, 128 ) end )

Example

Acquires and uses one of the Post-Processing Materials to make the screen darker and more saturated

local mat_color = Material( "pp/colour" ) -- used outside of the hook for performance hook.Add("RenderScreenspaceEffects", "ColorExample", function() render.UpdateScreenEffectTexture() mat_color:SetTexture( "$fbtexture", render.GetScreenEffectTexture() ) mat_color:SetFloat( "$pp_colour_addr", 0 ) mat_color:SetFloat( "$pp_colour_addg", 0 ) mat_color:SetFloat( "$pp_colour_addb", 0 ) mat_color:SetFloat( "$pp_colour_mulr", 0 ) mat_color:SetFloat( "$pp_colour_mulg", 0 ) mat_color:SetFloat( "$pp_colour_mulb", 0 ) mat_color:SetFloat( "$pp_colour_brightness", 0 ) mat_color:SetFloat( "$pp_colour_contrast", 0.5 ) mat_color:SetFloat( "$pp_colour_colour", 5 ) render.SetMaterial( mat_color ) render.DrawScreenQuad() end )
