I am trying to repeat the shader from the video.

Use way more "AO" many layers of it.

Also use some kind of "aging" texture for the particles. Id suggest toning down the noise map.

It seems that your material is pure flat shader, add SSS it will help a lot.

Why SSS? It supposed to be molten steel and metals doesn't have SSS at all. Emission and glossiness variation should be enough.

I've been picking up the settings for the AO and noise. Came to a the conclusion that it is necessary to draw a mask manually.  So there is still a lot of work to make it look decent.

Here is what author writes - "We used SolidAngle Arnold as our render engine and Cinema 4D software for the design boards on this one. The biggest challenge was to keep the flames/shaders believable but stylised and crafted to the story at the same time"

I have encountered that kind of map onse.

It should be a Blend of Light MTL and some sort of metall. Just play around with masks in mix amount. In this lexus scenario i would sugest blending Metall with translucent effect blending trough falloff map mixed with AO map and some texture for diversity.

For example here i used AO + gradient ramp + noise
