I keep on trying to get them larger than 1200 pixels, but its not working very well. And this is a brand new computer, 2.8Ghz processor, 512 MB DDR ram, etc, etc. Help! :)

For me anyway, trying to resize a flame image is extremely CPU intensive. ( i make mine on a P3 733.. its old but trusted lol )

This is taken from the Ultra Fractal FAQ page-

" Flame fractals and Out Of Memory errors-
Ultra Fractal 3 can calculate flame fractals with the Flame Fractals coloring algorithm in enr.ucl and Apophysis. This opens up new artistic possibilities, but it can also create problems. Flame fractals take a lot of memory to calculate, and they cannot be rendered to disk or used with network calculations. These problems may be addressed in a future version of Ultra Fractal. For now, have fun, but use them at your own risk."

Sorry i cant be much more help, but someone else with a bit more technical experience might be able to :)

Thanks anyways, I appreciate it. I guess I will just have to stick with 1200 pixels! :)

The way I have created Flame Fractals has drastically changed over the last few weeks! Since I have started to use the AEFlame plug-in (http://neosapien.net/flame/) for Adobe After Effects I have found no boundries that can limit what I want to create. Everything from 3200x2400 still images to flame fractal animations in any output resolution. Yes, Edobe After Effects may be a little more expensive than all/most fractal software available, but believe me the results can be amazing...especially if you are use to the the compositing options available within AE. I hope to update my site within the next 6 weeks with some flame animations done in AE (sorry, have a visit to Russia to organise in between). I was totally shocked with what I could create with just a little work. Cheers
