Any image file can be used as a texture, so long as both of its dimensions (height and width) are a power of two: 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048 and so on. To decide which to use, examine existing textures that fill the same role as yours. Higher resolutions lower performance but make an image sharper when viewed up close.
Different classes of object have different standard resolutions (e.g. character models' are very high). Check Valve's choices in source materials.gcf
with if you are ever confused. ****
Textures must be converted to the before Source can use them. The tool Valve provides for this is . It's a tool with quite a few limitations, so the third-party tool is preferable: it provides a graphical user interface, allows you to change a texture's properties without re-compiling it from scratch, accepts a wide range of image formats, and doesn't require the creation of script files for each and every texture. There are a handful of situations where you'll need to fall back on VTEX... but only a handful (Animate texture with ).
Also, if you have textures that use transparency, it is recommended that you save in TIFF format before importing to VTFEdit as PNG transparency tends to have problems. (There are VTF plug-ins that let you save to the format directly from , and , but this tutorial will not cover them as not everyone uses those tools).
To import your texture with VTFEdit, use File > Import
or press Ctrl+I. Select your image and you will be presented with the import screen:
There settings are the most important. There are three:
Normal format
The color/compression format that should be used if the texture is opaque.
Alpha format
The color/compression format that should be used if the texture has an alpha channel.
Texture type
Finally, save the file somewhere under your game or mod's \materials
folder.
A material file looks like this:
With a shader chosen you're onto parameters (also called commands). There are hundreds of options for what to put in a material so this article will only cover the most common, which are accepted by more or less all shaders. They are:
If you imported more than one image, this determines what they will be used as (animation frames/faces/depth slices).
If you're making a plain and simple world texture you won't need to change any of these. If you're making a texture with fine gradient detail however, you'll need to choose a.
are low-resolution versions of a texture that swap in when a surface is far away from the camera. They greatly reduce the amount of texture resizing needed, improving both performance and image quality. Mips are required for texture to work.
**Tip:**Textures that will appear in the 3D world should have . To conserve memory, textures that will only be used in a 2D interface should not.
The following images demonstrate the various filters available in :
These (mis-labelled) settings allow you to automatically generate a from your input image. You'll want to do this properly with an image editor for the material you ship, but the automated option is there is you want quick results or a base to work from.
When you hit OK the input file is converted (there may be quite a lengthy pause for large images) and the output VTF appears. Now all that is left is configuring the texture with the options in the checkbox list on the left-hand side of the screen. See for descriptions of each.
Source doesn't access textures directly. Everything goes through a .
are script files that can be created in any text editor, but it's recommended that you use one of the in conjunction with the community-made . For your material to be detected, you must save it under your game or mod's \materials
folder with the extension .vmt
.
Note: If you are creating materials and textures exclusively for a map for a existing mod, consider using \\\ to package the material and texture files within the map file itself. This will avoid them ever becoming lost.
There are many to choose from, but most materials will use either () or (). The third most common shader is , which is used for materials and the occasional .
