Nice tutorial, especially to showcase the Pyro Spread. Some notes for Houdini 19.5: 1. Pyro Post-Process does not have the same parameters as in Houdini 18. Actually the parameters of the Pyro Post-Process node also exist in the Pyro Solver node so I'm not sure why it exists at all. 2. The blue flame effect can be achieved by using a Pyro Bake Volume node and following exactly the steps of this video with the following exception: in the Pyro Bake Volume node go to the "Bindings" tab and in the "Fire" drop-down menu change the Intensity and Color Volumes to "flame". This is done because there is a slight problem in Houdini 19.5 regarding rendering this scene with Mantra that I will explain below. 3. I found out that the fire was not rendering at all with Mantra. The problem was the density attribute, which was missing. Giving the fire even a very small density (0.001) allows for the fire to render normally. But, if you add density and you don't change the "Fire" parameter in the Pyro Bake Volume to "flame" and leave it to its original parameter (density) it will create a blue smoke instead, hence why in the above step we changed said parameter. Feel free to check it out and perhaps create a new tutorial updated for the new version of Houdini. Also completing it with a render pipeline in Mantra and/or Solaris would be awesome.
hi, where do i find the density attribute and how do i add it? i'm having trouble rendering the fire too with h19.5. thanks. edit: interesting after noodling around i found that if you go to the fields tab in the pyro solver, you can enable density there by checking the emit from flame box which renders the flame now via mantra. thx for getting my neurons firing.
Hello Mo, thank you for sharing. I have a newbi question. I'm trying to use the Pyro SOP Solver with Redshift. I created a RS Volume and connected to the volume channel of the Redshift Material and I can't even see the fire in the render. I did also put the volume contribution scale of my HDRI to 1. Have you any suggestion ? EDIT 1 : I found a way to see the smock : volume contribution scale of my HDRI to minimum 10.
Thank you guys for the awsome video! I am a total beginner to houdini maybe you can answer my question: Is there a way to animate the noise, to keep the fire moving around the surface? Thanks again you guys are great!
Can anyone please point me to a resource talking about how to do this with pops as triggers for the spread? ive looked everywhere but there doesnt seem to be a straight forward answer anywhere, similarly using pops with the new pyro spread node seems to break it as well. i cannot figure out how to use pops for infection solvers of any kind help or advice would be greatly appreciated
Thank you for your tutorial. I've been start using in houdini 19.5 but seems the pyropostprocess is change as well. didn't have any slider for change density and the colour as well. Could you help me? Thanks
Thanks for the video. How do you render this look out in Redshift? I've been trying to get the blue flame look but it seems like it's not possible in the same way?
hey, the tutorial is very nice but have one question. I am using Houdini 17.5 so does not have pyropostprocess node so, instead of this what I can use?
I think something is missing because when using the pyro-spread, it is causing problems and it is also not animate... Cloud u solve this plzzzz..... And yaa when I click the node of Pyro spread open one box open CL , means

Nice one thanks for this
Крутые уроки!!! Thank you!

thanks for video. About terminology - is flame (fire) effect a motion design or VFX or particle system essence?
Thank you guys for the awsome video!

Thanks again you guys are great!
You can modify the source by a volume VOP and then multiply the density by the noise Then hook the offset to the time input. Hope it helps

pyrobakevolume is the new version
It's amazing if Chinese special effects artists are like this

Hey If you find out how to render it do tell please! I am on the same boat
You probably need to import the Cd Attribute into a redshift volume material.
hey, the tutorial is very nice but have one question. I am using Houdini 17.5 so does not have pyropostprocess node so, instead of this what I can use?
My advice would be to just download Houdini 18 - the apprentice version is free. Cheers, Mo

pyrosource1-initialize-Source Fuel
worst tutorial
nothing happens after pyrosourcespread
sorry for you, it worked for me
try removing the fuel and temperature attribute it creates automatically that's how i fixed this step
