ET-Tools for Mappers & Modders

ailmanki and isbowhten pointed in this thread in the SplashDamage forum to a few interesting things wich are of use for mappers and modders. Most people will already know it (the tools was made in 2002), but it's not wrong to report about it.

Q3A Shader Editor:

Textures in Quake3:Arena are no longer a simple texture combined with a lightmap, but are fully scripted entities which can be used to control practically every option OpenGL exposes when it comes to texture positioning, transformation, blending and whatnot. To facilitate the creation and editing of such scripts, this tool will parse a script and present it as a Windows GUI which is easier to understand and navigate than the bare C-like text files.


The goal of this tool is to create a new texture that looks "similar" to a given input texture, and tiles. This is easier said than done, so in practice this tool is trying to make the result look similar, and tries to make the resulting image tile. This means that this tool may or may not be useful; it depends on the input image, and some luck with the statistics. Ideally, input images should be true textures : uniform throughout, without macro structures. In practice, some structure is allowed; but still, don't expect this tool to work properly with a pic of your dog.


This tool implements reaction diffusion, a simple technique to generate textures by smoothing them out. The difference with a regular blur filter is that the texture pixels are interacting : pigment flows from one cell to the next (technically 'diffusion', but called 'Smoothing' in React), while at the same time pigment disappears and reappears (the 'Growth'). The net results are textures that have a blobby, sometimes 'viral' look and feel -- and they always tile.
