Hey Everyone, I know this question has been posed a million times, so if a tutorial exists, please point me in the right direction. I'd really appreciate it. I have tried a ton of tests to loop fire seamlessly in CS, and none of them have yielded decent results. Once upon a time, someone suggested using Infinite Textures for looping texture animations but alas, I cannot find that application anywhere. Is there a way to loop fire primitives (or particle emitters, possibly?) in CS? Any ideas, suggestions, tips or recipes for quiche would be greatly appreciated. Thanks! Todd

You could try using the procedural fire shader that comes with CS [see image]. It seems to animate well no matter how long your animation is (go to the first frame in the time line, and set the completion parameter to 0%, skip to the end and set it to 100%). Using ctrl+drag-drop, you can copy the fire shader from one channel to another really easily. You can then put it on a plane, or use the billboard primitive if you have Anything Grows. You'll want to remember to set highlight to 0, and turn on "no light interactions when fully transparent".

I find that the particle systems are good for doing the sparkers, but i've never really had any luck with the volumetric fire.

Alternatively-- though I've never used it-- ZMorphics [ http://www.zmorphics.com/ ] sells PPEx, which has a plugin for particle sprites, allowing you to use the billboard technique on individual particles.

EMC! THANK YOU in the most king sized of fashions! I tried your suggestion and it works incredibly well. Thanks again... I reeeeeeeeeally am thrilled to be able to seamlessly loop fire, now. I've had a project on the backburner for way too long because of my initial lack of success -- now I can complete it and get on with some summer vacation action (well, psychologically at least)! Todd
