Houdini Fire Simulation | Axiom | Karma Render
Realistic fire simulation created in Houdini 20.5 using the powerful Axiom GPU solver. I have also use GPU based Karma XPU rendering in solaris. It is very strong to get quick renders along with nVedia Optix Denoiser. At last I used nuke and its upscale technique to get hires resolution output without loosing any quality. You must use OCIO aces 1.2 or higher to get similar output. I have kept file prety clean and optimized. Simulation will depends upon asset, its size and values. My orignal setup was not procedural but, I have kept this one systematic and also my final result was done with voxel 0.006/7 and temperatue value - 4.Versions UsedHoudini 20.5.654Axiom 3.3.079if you need just simulation setup pls look at "Houdini Axiom Realistic Fire Simulation"What is included Complete Simulation setup. Karma shading and rendering workflow. Asset link is included. 2 version of FFR render of my test in karma. Single frame cache. What is not included Nuke Script. Asset and Texture [Path is given to download] Imp : Quality will depends upon your resolution and how strong is your GPU. If u have 4gb gpu then u need to sim at low res only.Youtube Link : https://youtube.com/@vfxhub4?si=GQtVHfLNaq-IEgz_🔧 Workflow Breakdown:🔥 Fire simulated using Axiom (GPU-based solver)🌎 Solaris (USD workflow)🎨 Shading & rendering in Karma XPU (GPU based)🚀 Final quality enhancement using Nuke upscale technique (upscaled to 4k)Simulation Details :Voxel size - 0.008 [my final result is with 0.006 and temperature = 4]Sim Time - 30minRender Time - 5min per frame (16-32 samples xpu render)Total Frames - 120My system details : Ryzen 9950x | 64gb ram | rtx 4060ti
