[2.91] Blender Tutorial: Quick Smoke Simulation for Beginners

hey everyone my name is olaf and in this tutorial i'm going to teach you how to make this exact simulation in blender using the built-in blender physics as always it's going to be quick and easy so uh let's get started okay so let's start off by pressing x to delete the default cube and then press shift a and let's add a sphere which gives us a bit more interesting smoke and then let's go to objects quick effects and then quick smoke so that we get the basic smoke settings for the sphere and then press s to scale up the domain which is the border of the smoke simulation and then press g then set to grab it on the z axis and then let's go into the simulation settings under the physics settings and i'm going to increase the resolution so let's set it to 100 for now and then next let's enable the adaptive domain and the adaptive domain will decrease the baking time because it adapts to the simulation and let's add some additional resolution as well for the adaptive domain to increase the quality of the simulation and then let's add some noise to the smoke so that the smoke doesn't look that smooth and instead looks a bit more realistic and then i'm going to set the type to all so if we can bake the simulation and then let's do a test bake at a lower resolution and i speed it up with this part as you can see we now have a very basic smoke simulation so let's add some lighting before we improve the smoke simulation itself so let's go into render view and then let's switch to cycles and i'm going to use the gpu and set the number of samples to 50 and if you have a gpu make sure to increase the tile size for a faster render and then let's change the light into a sun and set the strength to 5 and because we want more smoke i'm going to increase the length of the simulation so let's set the end frame to 400 and then next we can select the domain and then go into the domain settings and let's free the previous bake so if we can create a new one set the end frame to 400 and then let's scroll to the top and increase the resolution if you have a fairly normal computer i recommend setting it to around 200 or 300 and then next i'm going to add a force field a turbulence force field with a strength of 0.2 to give the smoke some variation and then let's save before we continue so i just give the file a name and then press enter to save and then next we can bake the simulation once again but this time with a higher resolution and after about an hour of baking on this computer we have this very basic smoke simulation as you can see when we move on the timeline and we want to see what it looks like in render view you can just switch to render view so let's see what the smoke looks like and it looks nice so let's save before we continue so uh file save as then click on the plus sign and then save and then next we can drag the top right corner of the window and now we're going to go into the shader editor to edit the thickness of the smoke in renderview so let's go into rendered view and then we can change the density of the smoke which controls the thickness of the smoke as you can see so i'm going to set it to around 6 which is slightly higher than the default value and then we can drag the top right corner of the first window to remove this window okay and then i'm going to hide the sphere in rendered view and in the viewport if you do not want to hide the inflow object you can just keep the visibility on and then i'm also going to make the background a bit darker so if we can see the smoke a bit more in contrast to the background okay and then next i'm going to uh go in to the camera so press ctrl alt number 0 to set the camera to the current view and then press n and lock the camera to view so something like this and press g to grab the camera and as you can see this is a smoke simulation that obviously fits the instagram one one aspect ratio the best okay so let's set the resolution to 4k and then select a folder for the rendered images so i'm going to select the large renders folder and you can of course save it wherever you want on your computer i'm just going to call the folder smoke easy and then give the render a name and then after the render is done you can just convert them from png to mp4 i have a tutorial on that topic on youtube just search png to mp4 and you will find a very quick tutorial for that and then let's render so let's go to one of the later frames and do a test render for one image and see if it works correctly so render then measure image and i think it looks fine so the next step will be to render the whole animation so let's close this window and i'm going to change the position of the camera slightly before i render the final animation and this is the time to make the final adjustments and once you're happy with the adjustments you can start the render okay so let's go to renderer and then render animation and that's it for this tutorial i hope you enjoyed it and if you want more smoke simulations and physics simulations in general make sure to like and subscribe and i will probably make more of them very soon
