I'm trying to add detail and grunge to my vector based designs through the use of procedural textures.
Currently, I'm using the noise filter, and the sponge filter on a grey rectangle as multiply or soft-light layers to generate effects that are similar to what I'm after but the level of control leaves much to be desired (specifically, I can't control the size of the effect, nor can I control the colour range without more work which is a hindrance when I need to test multiple times to achieve a specific effect).
In 3DsMax or Maya there's a plethora of procedural texture options available which are not only processed much quicker then using the photoshop effects in Ai, but also allow a greater amount of control.
Is there a method in Ai, whether it be native or through the use of a plugin, where I can achieve the effect I'm after?
