Hi Mags - All you have to do is click "File/Export Upr" then browse to your UF parameters folder and give it a "File Name" like "C:Ultrafractal3DateParametersFLAMES.upr" - give the flame a "Title" in the box below that will let you know what it's name is in Apo and you're done. Real easy. You can save LOTS of your flames to this same "File Name" with different titles and when you open that .upr file in UF, it will have a list of all of your flames and you can select which you want. You can even have different .upr files with different names in UF to categorize your flames. Like C:UFxxxxxxxCIRCULAR FLAMES.upr or C:UFxxxxxxxxFLAMES THAT LOOK LIKE MY WIFE WHEN SHE'S PISSED - lol Apo was originally written as a plug-in for UF. IMO, it's the only way to go if you want to make compositions of multiple flames or flames with straight UF layers because it's so easy to re-size, rotate and re-zoom flames in the UF environment. Check out my gallery and you'll see some stuff that's possible to do with flames in UF. You can also tweak the gradients on your flames in UF and point your Apo gradient browser to your UF gradients folder and be able to use any UF ".ugr" gradient you want in Apo. c-ya! Rick
