How to run it?" {There are different ways how this script can be used: Type at console: texture - run GUI texture 'preset-name - return image! according to the preset name texture [dialect here] - return image! as described in dialect or you can use other functions: request-texture - shows requestor, you can select preset and returns image!. or texture-styles - put in your layout [styles texture-styles] and two new styles are ready to use: texture-tile - just supply same dialect as for 'texture. The texture is ALWAYS tiled! texture-text - renders textured text that can be used for labels, logos... } "2. How does it work" {First, noise image is created. If one color is supplied, noise is BW, with two colors noise is gradiental. Then the noise is effected using pre-effect. The result is effected strength-times using engine. Then the post-effect is applied and if one color was supplied the result is colorized. That's all and texture is ready to use. When using tile, noise picture is created in normal size but then new picture is made, 9xbigger (grid of 3x3 noise images) and all effects are applied on that picture. Only the center is cut-out and used. } "3. About" {Texture Lab version 0.3.3 ------------------------- Written by REBolek aka Boleslav Brezovsky.
