Fire Spread Tutorial in Houdini

hello and welcome to this new tutorial which is fire spread tutorial which i have made this one [Music] so to do this we need this animation so for this i am using mix mo animation which is from the site this makes samos site you can choose any character whichever you want you can upload your character then animations so i'm using this character this is my previous tutorials connector which is a superhero landing tutorial and in this tutorial i am using simple this standing idle animation which is three this one so to download this you just download this with skin which is which will come in fbx format to use that fbx format jump into rodney you can either call it or you can import so i'm importing it so file import film box fbx and just import that standing idle zero three or you can use any one then import it will import that same and it is here so this is like old animation old character i am using it has all these bones and animations so what do you want to do just disable this display flag and use geometry node and here use object merge to import that animation so just go to the standing idle and go down these are the geometries this is first and it has some other geometric part so use our object merge again and use second one then merge both of them okay and distributional object so now you can see it has all the animations you can use as it is or if you want to use as a alembic you can use this rope alembic output it will output as alembic then you can reimport it whichever you want so that's how i used all my animations to convert to lmb i have more animations let's just use one more here which is think this one this one this is the same okay and just use switch node to show you and one more thing these are very big objects so let's scale them home so [Music] okay so this one is actually very big so just scale it down same for this second one [Music] and just convert this okay now both are scaled down now you can use any one whichever you want for fire spread i am using building tools so let me just save this as a tutorial [Music] okay so for this i am using this built-in tutorial oh sorry built-in nodes shelf node this one i'm using this one spreading fire select this click on object and enter it will create all the necessary nodes okay so just get back and it created these nodes which is a source node summation node and import node so in source node it has all these points and it is using this object to start where to start this fire currently it is starting from head on different location you just pause it select this object and move anywhere you want it will start from there if you want like on my book somewhere this one it will start from here so and main come to this simulation spread it actually control the spreading of the fire so if you go to total bud it will show you the spreading as a visualizer [Music] see [Music] and if you want see spreading is like slow if you want fast slow fast or slow you can always change these values this will control the spreading and all these values so if i go to like if i increase this value and if i increase too like then it will spread more faster [Music] and you can change this search radius also i delete this and just use one okay and if i just use two [Music] okay you can use these values and if you want more points you can always go to this point section and decrease this value and it will have more points if you want different object if you go to let me switch to other object if i switch to zero [Music] my geometry is still made [Music] five okay i think five is enough and i can go to source and again uh you can always increase this box i think box is small or maybe three or you can use any different objects just put it above its head okay and i think i'll move this forward okay okay now it will spread from here so now it will grow to all its body okay so if you want more detail just you can give this sub step it will increase sub step and it will spread off mode or more faster okay so let's go to just to none go to main simulation which is this one and you can either crease or decrease these values and um let me just use this value 0.01 and close below so below ground it will act as the ground [Music] and in pyro solver you can always increase temperature and all that values my own c3 and flame shape sub steps everything is here you can play along it so let me simulate for a couple of frames okay it has some simulated couple of things but still it's slow you can always go and change the rate of that and if i go to fire import it has this post process volume you can always use smoke and all that i think if i use one will show some smoke also okay so for rendering and i use this v-ray [Music] okay so let's just used grid for ground and [Music] camera nothing i need material and for this i'm using this material for ground [Music] and for volume i'm using v-day volume and if i go to grid apply this video material this one and for same for this character then for fire i may use this volume okay and let me just use smaller frame [Music] okay less [Music] under setting just use rtx and video frame references [Music] okay so it's not showing because we need to define something here in fields color is defined by flame see and it is using this light i am not going to use default light disable this and how it will have genuine light okay you can use this increase multiplier and for this material let me just go for it this one a little bit glossy [Music] and simple light [Music] negative 19. [Music] and then i used 5x5 [Music] yes something like that it will have all these values okay so of or if you want like skeleton to different material just use different material [Music] just use porcelain [Music] okay so there you have it that's how i created this fire spread okay you can use this and as all and if you want to use this glow option you can always use [Music] glow option in v-day so for light i think [Music] slightly [Music] [Music] [Music] so [Music] [Music] and after that you can use this glow option [Music] yes this one how much you want it's up to you okay so this will be your tutorial you can use animation any animation any object that will be used okay and goodbye
