  1. Swirl Pyro Equivalent

    All good answers- The vorticles seem to be closest to for me, but motion-wise Ill have to mess around to get something as nice as the swirl attribute.
  2. Swirl Pyro Equivalent

    MVP : ) thanks
  3. Swirl Pyro Equivalent

    the patterns caused by all these nodes seem to be turbulence patterns not circular swirl motion
  4. Swirl Pyro Equivalent

    I tried messing around with that setting, but it did not seem to do too much. Ill try it again tho.
  5. Swirl Pyro Equivalent

    Hey, I have been struggling to get a nice swirling motion in slower moving pyro smoke simulations. In Maya fluids I had an option called swirl witch worked beautifully. I found an old post addressing this issue, but it seems to have died before arriving at a good solution: http://forums.odforce.net/topic/23132-smoke-swirl-vorticity-with-smoke-solver/ Here is a simulation I did in Maya using the swirl attribute. https://youtu.be/Ifd6FJ2oHIc In houdini I have been using disturbance but I don't seem to get the results I want. Disturbance doesn't really seem to add swirl but more turbulent detail. For example, look at this sim I found on vimeo. You can see the disturbance start overpower the simulation towards the end, it doesn't really add a swirling motion. https://vimeo.com/220668349 What is a good Idea to get nice swirls? Thanks
  6. Mixing Pyro Colors

    I had one more question, why can't I use any of the inputs on the pyro shader? For instances, if I make a constant change it to color and plug it into the smoke color nothing happens.
  7. Mixing Pyro Colors

    I found if I add a volume vop (after dop i/o) I can access the Cd and change the color

    Thanks, ill look into this
  9. Hi, I have been working to create a pyro simulation with multiple colors. I did this by giving my particles different colors then in my fluid source node use the attribute Cd in velocity volumes. I use that as a vector field in dops. This method works, but if I want to change the color I have to re-sim the whole thing. Is there anyway to modify the Cd attribute colors after the simulation? I just seems like there must be an easier/better way to get multiple colors in a pyro simulation. It seems like I should be able to set to colors like red and blue and simulate that. Then at render I can modify the Cd colors to what I need. Or is re simulation something that just needs to be done? It just doesn't seem art direct-able if I have to re sim every time I need to fix the colors. thanks in advance. explosion.hiplc
  10. Vector Field & Gas resize

    Haha I am dumb : ) thanks
  11. Vector Field & Gas resize

    Gotcha, I added a gas resize field and that did the trick. thanks : )
  12. Vector Field & Gas resize

    I am not sure where to plugin the gas match field, but I plugged it into the pre-solve. When I match it to the density it creates a new problem. The color vector fields stops matching pyro. The first photo you can see it did resize the container to match, but there is a problem with the vector field. thanks btw : )
  13. Vector Field & Gas resize

    Hi, I am trying to add different colors to my pyro simulation. I have a vector field for the color. How can I make it adjust the size of my vector field to match my main pyro container? My main pyro container has a gas resize fluid dynamic node. How to I make the vector field adjust with the gas resize fluid dynamic? Thanks explosion.hiplc

    I see, thanks for the clarification!!!

    that works pretty well, but once my particles die the fluid suddenly stops going in the direction they were : ( I guess it happens in the example video i posted as well
