Exhaust/Thruster shadder for Cycles

[daviddomingues]

Hi!
I’m making a sci-fi short and I’m trying to create an exhaust/thruster effect for a spaceship and I can’t seem to get it right

There’s some example online like this:

Blender3D - Visceral Rocket Exhaust Flames without Particles

Blender spaceship thrust test

But they don’t seem to work

Thank you!

What did you try? Blend-file?
