I just uploaded a gradient file for use with UF 3.0 or higher and apophysis. Most of the gradients in this file were created using apophysis and my own digital art images, and are geared towards use in apophysis. There are 55 gradients in all in the file, and a readme file on how to install them and use them. Here's the link to download them: "5DS UF 3 and Apophysis Gradients ~ 55 Gradients" Or you can go to my homepage on Renderosity, they are there, too.
