Hello folks, I am trying to re-create the "rocket exhaust expansion effect", when a rocket goes up and the flame is expanding because of the thiner atmosphere.. I have now 2 particle simulations, which are my main source for my pyro simulation.. but when I attached a pyro sim to the particle sim, then there are small flame points: as seen on my screenshot.. (it was rendered with Blender, Cylces)... and it also looks that ugly in Houdini... how can I achieve the wanted effect like on the reference picture: and how I need to set up my pyro sim, so that these dots will dissapear and will get visible as a seamless flame like on the reference picture..? - I have tried to add substeps but But the main thing is, that I am following the SpaceX Starship programm, and there will be a much bigger Rocket with more engines... And now i am wondering how can I create this massive flame which will be produced by this massive rocket... I have attached 2 images, and 1 video, where I am showing my current particle simulations: one image my current simulation... the other image is the reference image... and the 3rd image is the problem which I am facing right now... I would really appreciate some help from this community, thanks in advance Daniel 2022-05-11 14-03-50.mp4
