  1. Rocket exhaust - Particle based pyro simulation

    Thank you, it looks better, but I dont know how to give more fuel to the outer regions so that they should be more visible...
  2. Rocket exhaust - Particle based pyro simulation

    Rocket exhaust expansion_test1.hipnc so here is the hip file for you
  3. Rocket exhaust - Particle based pyro simulation

    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
  4. Attach pyro sim to insane particle speeds

    Hello I have set up a particle simulation, where the particles are moving with fast speeds.. now as I am rastarize them and bluring the edges, I still get pointy smoke... then I have add some substeps to the smoke sim in the pyro solver node, but still the same result.. does someone knows, how to tackle this problem and get a nice and flowing pyro sim with a fast particle system? Help would be much appreciated
  5. driven smoke simulation with particles dont collide with the geometry

    lol where is everything?! I cant see the particles and also the smoke xD I am enabling the blue flag but still nothing there!
  6. driven smoke simulation with particles dont collide with the geometry

    here are the files... Tank farm venting.hipnc tankfarm.obj tankfarm.mtl
  7. driven smoke simulation with particles dont collide with the geometry

    Also, please need some fast help, because I am on a deadline project until next friday!!
  8. Hey folks I have set up a particle simulation where I have then attached a pyro sim to it (through the rasterize attributes volumes node)... Also I have imported a few objects where the smoke sim should interact with... Everything is fine, until one point: When I am wanting that the pyro sim should collide with the object (seen on the screenshot), then the smoke is just going through the "wall of dirt" (its just a wall with some grass and dirt... ) I just need the collisions so that I can then export the smoke simulation as a vdb sequence... What I have tried so far: - I have give it more thickness with poly extrude node (also added the collision guide thing to look if everything is fine) - also I have increased the substeps on the smoke sim - I have add a object merge node in the pyroFX node (as seen in the screenshot) - just ignore this one node where I have add the red line... But everything I've tried so far, I got no luck to fix it..
  9. Smoke simulation driven by particles

    Thanks! But I already figured out the problem by myself And sorry for the late reply, I kinda forgot about this xD
  10. Smoke simulation driven by particles

    Hey folks, I am messing around with a particle simulation. Now I want to hook up a pyro simulation which will be driven by the particle sim. This is my smoke sim setup from the particles: (it would be awesome if someone knows, how I could set it up so that there will be the typical smoke mushrooms visible during a rocket lift-off). Because I can't figure it out how to make the smoke going outwards and not just sticking to the particle simulation.. I have tried to increasing the turbulence and disturbance in my pyro solver to break up the thing that the smoke is sticking to my particle sim... but this hasn't worked out yet. Help would be much appreciated Thanks!
