  1. Hello; Please take a look at image bellow. When I add background to my camera, some artifacts appears in middle of my fire. When I turn off background, fire is OK. I can't figure out why camera's background image rises this problem. Thanks for helping.
  2. fire from small source

    Hello!! I have a simple fire simulation using the smoke solver that is using a bush as a source. Do you guys have any recommendations for sourcing on small objects? The bush is incredibly thin in some areas, so it seems the only solution is to crank up the resolution in volume rasterize attributes and the smoke object. Of course it becomes realllllllly slow. Any other ideas that might help speed things up? Thanks

  4. House fire sourcing Pyro

    Hello! I am trying to achieve an effect of fire coming from a window. I am unsure how to approach this. The goal is to have a flame that comes out of the window, and smoke drifts slightly to the left. Currently i have a deformed sphere, as my source geo. It looks ok, but i feel like there might be a better way. Any suggestions are appreciated. https://www.youtube.com/watch?v=SAh92E4UMFw Reference at 3:00 https://youtu.be/s-UOhgKVtQs?t=179
  5. Hi Guys; I tried to create a small fire like a matches flame, but my problem is what I see in viewport is very different from render output. How could I fix this? Thanks. Flame_01.hip
  6. Hi; I tried to achieve a smooth shape and calm fire as a matches flame, but as you can see in image bellow my fire is in a crazy shape..! How could I control shape of fire to make it smooth? Any comments will be appreciated. Thanks.
  7. Horse Mane and Tail on Fire

    Hi Guys , I am a newbie to Houdini and I have a small scene with a horse run , I would like to have my horse's mane and tail be on fire, i don't need a big smoke trail tho. was wondering what is the best approach to create this effect and any reference tutorials or hipfiles that I can look at to get an idea for this . any advice is helpful. thanks
  8. Create a Trail explosion in Houdini 17.5

    Hey all, I am trying to do a explosion like this in the picture. I am very desperate, I have searched up the whole internet around but have find nothing... I have tried to do some particle emitting from a sphere with some forces but it wasn't like this... Can someone help me please... ps. if someone have time to make a hip file for me it would be a bigger help thanks in advance,
  9. I am having a really tough time matching the reference of cannon firing from an old pirate ship. I am not able to get the smoke quality and shape or the wind that picks it up. My sim always ends up looking too powdery or thick. If I lower dissipation then the fire or explosive part remains too long. I would be grateful for a working scene file or a setup. Here is the reference:
  10. Fire on the ceiling

    Hi everyone, I'm currently trying to create an effect of fire burning under a ceiling, looking something like this: http://footage.framepool.com/en/shot/774901137-explosive-flame-fire-disaster-ceiling-fire-blaze As far as I understand the phenomenon there is a layer of gas floating between the air below and the ceiling above. It gets ignited and starts burning at the interface between air and gas. The flames rising up create this kind of nodule structure by constricting the gas into little pockets. This is the theory but I'm completely stumped on how to create the actual effect. I've tried creating little pockets of fuel but the pyro sim simply burns into them, disregarding the fact that there should be no air that makes combustion possible. Does anyone have some experience with this kind of simulation or at least an idea how to tackle it? Any help is appreciated. Thanks in advance Paul

  12. leaf burning

    Hello everyone! Any useful advice on how would it be possible to recreate this effect? Thanks Isy
  13. Hi magicians, I was trying to create render passes for the fire, I want my temperature and fuel to be render as different render passes, I tried to use temperature and fuel as float in extra render images, but the problem is that, I am not been able to get it properly. what is the way to get render passes for temperature, fuel and heat in extra image details ? I would also like to know the way to render normal passes and any other passes which can be rendered out from volume, like opacity pass or something helpful in compositing. I get the fire mask from the shader but it is not that useful. Thank you.

    A lot of people asked me to share this fake fire method.If you interested it, you can will check this simple hip. After rander i used ACES for a better look. fake_fire_rnd.hip
  15. Explosion Houdini

    Does anyone know good tutorials for learning Explosions? Thx in Regards
  16. hello guys, im working on a project for which i need to recreate this look in houdini i would really appreciate if some could help me figure out how to do the cape effect im kinda new to houdini and stuck at this effect.. working on a deadline please help out as soon as you can if possible thank you
  17. Hello im a student and pretty new to houdini working on a personal project can u please help me figure out how this effect has been made since im still learning & cant afford high end simulations i would be really grateful if someone could give me an in detail explanation of how to do this... its pretty urgent since i need to finish the project in the next 15 days.. Thank you guys in advance
  18. Can someone please give me an indepth explanation as to why the CPU vs GPU sims look different? I have noticed when making a fire sim, GPU gives a bit more streaky and jagged sim (better licks) than a CPU sim which tends to be a bit more billowy with more 'shrooms' or rounder shapes in general. Sadly GPU crashes on any large scale sims yet I really like the look. How can I get CPU sims to look as streaky and jagged as GPU? Any tricks to stop a GPU sim from crashing? Cheers!
  19. Hello! I want to present you my latest project! Did a test of cloud and fire, the video below. Hip_file is available for download hip file https://gum.co/IlDLG
  20. Hello, I am currently doing some RnD on a rocket engine. For this to work properly, I need a way for my emitter geo to shoot flames with initial velocity in the normal direction of the emitter. I made a gif to show the problem. Red is the emitter, the arrow represents the direction of the initial velocity. Right now, my simulation only shoots flames with an initial velocity in one specified direction. I used the "add initial velocity" in the create volume source node of the emitter. But I don't really know how to animate that. Appreciate any help, thanks!

  22. fire propagation

    Hey! I'm doing a pyro sim and I need to set some objects on fire, I'd like to recreate a sort of propagation effect where an object is set on fire on a specific point and then the fire run across the surface. I found some example where some people suggest to go for the "real" solution, set a volume with density and low temperature on the entire object and inject some heat and let it go. that's nice but I'm looking for a more art directable approach, because I'll have to be very specific on when some part of the object will be on fire or not...any idea on how to approach it? thanks!
  23. - Hello everyone im trying to render pyro sim in maya and the problem is fire doesn't appear, instead it show blocky voxel like in the render my setup was : created pyro sim from shelf (Exploison) exporting the sim after converting it to vdb, load in maya via arnold volume (grid density) added aiStandard to the volume, than aiStandardVolume to shading group (in this stat only smoke is visible) So when i try to make emission type "channel" and the channel heat i get this blocky voxel issue Thank you
  24. flame gradient shading

    hey guys! i m trying to make like reference image with houdini. but it's not easy how can make like this reference image?! i mean blueish -> transparency -> bright i need help! verrrrrrry thanks for any tips or advices.
  25. Plastic Curtain on Fire

    Hey guys! Was just wondering what's the best way to melt a plastic curtain with Houdini? Something like this - https://images-na.ssl-images-amazon.com/images/I/51hzskGD15L._SX425_.jpg I want it to melt and shrink in a way the plastic material behaves when it's on fire. There are many melt examples out there using flip but I am not sure how will I achieve the shrinking effect. If you guys can come with any ideas or point me towards the right direction, that would be amazing! Thanks, bifrost
