It's not "baked" to any specific asset but "just" a 3D texture

Yup! Using the 3D noise and applying a curl warp per (z)layer to get 3D tiling curl noise 🙌

Thank you! :)

@vfxlabs.net Yoo, I remember you asking how I did this effect! Well this is it :D

Thank you so much! It's part of a bigger project and I'm planning to post an extensive breakdown of everything once it's all done :)

Actually neither :) I am distorting a flame shape texture with a flow/distortion texture (two actually to break repetition). I'm controlling the strength of the distortion with dynamic parameters in Niagara to distort it with varying intensities that causes these lovely flame licks ^^
