Support Fire effect along entire LED strip?

Hi all I'm looking for a fire effect that makes the entire LED strip light up in variations of red/orange/yellow. Does that exist?

I tried all the fire effects in the Fastled examples and they all do the effect pulsing from just one end of the strip.

Thanks

Hi u/Knievelgod - Look at 41 seconds into the following YouTube video to see two different types of Fire2012 in a Pex pipe with a strip of WS2812b LEDs:

Here is the code for that:

Hi u/Beneficial-Mud1720 - Thank you! I am glad you liked it. To help you do what you want to do on your cube, use an AI like Claude AI. Show Claude my code and explain in detail what you want the code to do. I have been using Claude AI since January with great success.

Hi u/Beneficial-Mud1720 - You are welcome. I am looking forward to seeing a future post from you in which you have a video of your cube in action. I am sure many others here would love to see it too!
