Material_Parameters#511557

This page describes possible values for the second parameter of the <page>Global.Material</page> function when importing .png or .jpg textures, as well as some specific material key-values being set in that process.⤶ ⤶ For a list of all flags that can be controlled by settings the $flags int, see https://developer.valvesoftware.com/wiki/Material_Flags⤶ ⤶ Possible values are:⤶ ⤶ ⤶ Value | Description |⤶ ------|-------------|⤶ | nocull | Sets the [$nocull](https://developer.valvesoftware.com/wiki/$nocull) to 1 in the created material. |⤶ | alphatest | Sets the [$alphatest](https://developer.valvesoftware.com/wiki/$alphatest) to 1 in the created material instead of [$vertexalpha](https://developer.valvesoftware.com/wiki/$vertexalpha) being set to 1. |⤶ | mips | Generates [Mipmaps](https://en.wikipedia.org/wiki/Mipmap) for the imported texture, or sets **No Level Of Detail** and **No Mipmaps** if unset. |⤶ | noclamp | Makes the image able to tile when used with non standard UV maps or <page>surface.DrawTexturedRectUV</page>. Sets the CLAMPS and CLAMPT flags if unset. |⤶ | smooth | If set does nothing, if unset - enables Point Samping (Texture Filtering) on the material as well as adds the **No Level Of Detail** flag to it. |⤶ ⤶ ⤶ ⤶ # Additional Notes ⤶ When you call <page>Global.Material</page> with a file extension, the engine creates a material and a new texture from that file.⤶ ⤶ The created texture will have its size set to the closest [power of two](https://en.wikipedia.org/wiki/Power_of_two) size.⤶ ⤶ The material is given the following parameters by default:⤶ ⤶ ```⤶ "UnlitGeneric"⤶ {⤶ "$basetexture" "<set to the newly created texture>"⤶ "$vertexcolor" "1"⤶ ⤶ "$realwidth" "X" // The width of the actual png/jpg file⤶ "$realheight" "X" // The height of the actual png/jpg file⤶ ⤶ // Custom parameters⤶ "$nocull" "1" // Only set if nocull parameter is given⤶ ⤶ "$alphatest" "1" // Only set if alphatest parameter is given⤶ "vertexalpha" "1" // Only set if alphatest parameter is NOT given⤶ }⤶ ```⤶ ⤶ ⤶ ## vertexlitgeneric ⤶ ⤶ ⤶ ⤶ This is used in the VMT of most models that need correct lighting and shadows.⤶ You don't really need to worry about it for 2D textures though, since they don't need lighting.⤶ The other commonly used option is **unlitgeneric**, which makes the model have no lighting at all, similar to typing **mat_fullbright 1** in the console.⤶ It is unknown why it exists for 2D textures though, probably just for usage with <page>Global.Mesh</page>.⤶ ⤶ ## nocull ⤶ ⤶ ⤶ ⤶ This makes the back of the texture get drawn all the time.⤶ If you're working in <page>cam.Start3D2D</page> then it can help if you want a double sided texture.⤶ ⤶ ## alphatest ⤶ ⤶ ⤶ ⤶ This makes the material have an alpha of either 0 or 1, instead of a range between those values.⤶ It makes the alpha edges look very hard, but it can fix some transparency related problems.⤶ It can be used to allow alpha in stencils. If you're trying to use a material in a stencil with an alpha channel, use alphatest.⤶ [It also allows the flashlight cast shadows from the material](https://developer.valvesoftware.com/wiki/$translucent#Flickering_and_reversed_depth).⤶ ⤶ ## mips ⤶ ⤶ ⤶ ⤶ This makes low-res versions of the texture that it swaps out as it gets smaller.⤶ It can help improve performance, and you usually can't see the difference.⤶ ⤶ This can improve smoothing if you're scaling down the texture a lot.⤶ ⤶ ## noclamp ⤶ ⤶ ⤶ ⤶ This allows the texture to tile, so if you want a repeating pattern then it can help.⤶ <page>surface.DrawTexturedRectUV</page> will help you draw a pattern.⤶ It also stops the edges getting stretched, which can make it look smoother.⤶ ⤶ ## smooth ⤶ ⤶ ⤶ ⤶ This stops point sampling, which makes textures look like Minecraft.⤶ It makes the texture look smoother when you scale it.
