Smokeless Flame

This project is the first of a series on improving the look of smaller scale fire simulations, that is based on the 2022 Siggraph Presentation, Sexy Fires Will Not Burn Your Hands.

The file demonstrates the most basic setup to achive a gaseous transparent look at the base of the flame. However, this setup is not sophisticated enough to emit smoke from the tip of the flame what you would observe from real life references.

    Thanks for letting us know! These warning messages are not effecting the simulation. Previously the Update was set from Auto Update to Manual, maybe that's why it seemed that the simulation was not working. Also you have to wait 7-8 frames before you can see the flame rising.
