From this tutorial, you will learn an amazing animation of the explosion in the blender 3D program. As always this tutorial is full made for beginners with step by step. Don’t worry if you some trouble, just comment below and I will give my full response what I can. Also, don’t say that it is hard to learn, but I will say you that it is so easy to learn just don’t take this word in your mind that you can’t learn this. If you want to learn blender, then you can’t learn directly but you will need to learn its tips and tricks. So after all of this let’s learn how to make explosion animation. First in here I had some objects to make, also I had some steps to learn in a very easy way, I am just showing you the main steps, not the little one because there are hundreds of steps, but the main steps what I’m showing you “I am not doing that” it just for understanding you better.
- UV Sphere
- Domain of smoking
- Changing UV sphere to the particle system
- Border for fire and smoke
- Setting up the lamp
- Giving the flame effect to smoke with node editor
- Setting up the camera
First of all open blender 3D program. In the upper menu change the “blender render” to “cycles render”. Select the cube and press X to delete. Press shift A and make a “UV sphere” in the mesh. Press S and scale it half of the default map. Select the “UV sphere”, then go to the particle system tab in the right sidebar. Click on new, change the “number” value to 500 under “emission”. Change the “end” value to “2” under “start” also change the “lifetime” value to “7”. Now change the “random” value to “1” under “lifetime”. Scroll down and you will find another “random” option in the “other” tab, so change the value to “8”. Scroll down and uncheck the “emitter” option.
Go to the “object” in the left linear menu, then “quick effects” and select the “quick smoke”. Press S and scale it much bigger than the “UV sphere” and its default map. Press S Z and scale it oz-axis (like a pen). This frame will be the border of smoke and flame when they explode. Drag it to the top by pressing G Z to drag on the z axis.
Applying Particle Physics on UV Sphere
First, go to the physics tab change the “flow type” to “fire and smoke”. Also, change the “flow source” to “particle system”. Down bellow choose again “particle system” in “particle system. I hope you understand better than I think. Down bellow in the last on the left, check the “initial velocity”. Also, change its value to “0.25”. Above the initial velocity, change the “size” value to “4”. Hold your arrow on the size value and press I to add a key frame. Go to the 8 FPS in the timeline, and change the “size” value to “0.5”. Again hold your arrow on the “size” value and press I to add a key frame.
Setting up the Domain (border)
Select the frame object, in the physics tab change the resolution value to “150”. Change the “temperature” value to “0.05”. Scroll down go to the smoke flames menu. Hold your arrow on the “speed” value and press I to add a key frame at 8 FPS of the timeline. Than go to the 13 FPS in the timeline, and change the “speed” value to “0.1”. Again hold your arrow on the “speed” value and press I to add a key frame. Bellow the “speed” change the “smoke” value to “2.5”. Down select the “smoke adaptive domain” and “smoke high resolution”. Then you must save this project any where you want, because now the cache baking option is locked, but after saving the project the cache bake will be unlocked. After saving go to the smoke cache, and change the end value to 60. So after that let’s set up the lamp.
The Lamp (sun)
There is nothing special in here, so first, select the lamp. Go to the sun icon tab in the right sidebar menu. Change from “point” to “sun” down bellow in the menu. Also change the size of it to “1”, click on “use nodes”, and change the strength value to “7”. Grab it to the right place by pressing G. Make sure that the rays of the sun fell down below the UV sphere on the map (not too much). So now let’s change the background color.
In this paragraph, there is nothing special to changing the background color, but some easy work. First, go to the world icon tab in the right sidebar menu, and simply change the color to full “black”.
Applying flame with smoke
First of all, select the frame object, and drag all the tabs like what I’ve showed you down bellow in the image. After this step, change the “object mode” to “node editor” in the down linear menu of the right viewing window. Zoom it to see clearly. Press shift A and search for “emission”, connect the node from “emission” to “shader”. Press shift A and search for “attribute”, than connect it’s node from “strength” to “fac”. In the attribute node, there is a name option and write the name of “flame” in it. Drag the “emission” and “attribute” nodes to make some distant between them. Press shift A and search for “math”, than drag the math node between the emission and attribute nodes to connect them automatically, change the “value” from “add” to “multiply”, also down bellow of the node, give the value of “50”. Press shift A and search for “ColorRamp”. Connect the ColorRamp node “color” to the emission node “color”. Zoom on the ColorRamp node, and in the changing color place, you will see a dot type thing on the right corner, click on it. Below in the simple color changer, change the color to “black”. Now click on the left corner dot and change the color to orange bellow in the simple color changer. So that’s it we are done in the node settings, close the node editor screen by dragging the left viewing screen to right. Go to the physics tab in the right sidebar menu. In the smoke cache, click on bake, then wait until he baked. After baking let’s set up the camera.
First of all, press 0 on your num pad in the right of the keyboard to select the camera, then press Shift F for fly cam and move around with W A S D on Windows keyboard (I don’t know about Mac). Drag the camera where it fully covers the animation from start to end at 60 FPS in the timeline. Then select the camera. Go to the camera icon tab on the right sidebar menu. In clipping, increase the “end” value to “145.800” to focus the far objects. So finally let’s render it.
Go to the camera icon tab in the right sidebar menu. Change the resolution from “50%” to “100%”. Also, I change the size of it to “1280x720p”. Also on the right, change the “end frame” value to “60” because our animation will be end at 60 FPS. Change the file format to “H.264”. Also, choose your output folder above the file format. Bellow go to the “sampling”, in samples change the “render” value to “50”. If you had a powerful GPU then go to the “performance” tab, and change the tiles to “500”, but you have not then please don’t touch that option because that will crash your CPU. After that, scroll up and click on animation to render it. After rendering you will find an amazing animation of the explosion.
So that’s it our project is done.
