Khaos in Mantaflow
It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, and video editing. As a community-driven project under the GNU General Public License GPL , the public is empowered to make small and large changes to the code base, which leads to new features, responsive bug fixes, and better usability. Which can be automatically mapped to the foreground and background elements in the compositor.
This is especially helpful for adding background images to the render, or color grading visual effects. A lot of artists that work on VFX shots struggle with merging their render with the background image. Sometimes even when they match the lighting.
But there is one other thing that needs to be taken care of which is the color range. This is especially helpful for adding background images to your render, or color grading visual effects. This addon allows artists to create a fully animated ocean in Blender in a short period of time. Whenever we say Blender addons for simulation and visual effects related to ocean effects, this tool is probably the first that comes to mind.
Advanced Ocean Modifier comes with 3 Ocean Presets for calm or stormy weather and something in between as a third option. You can tweak all of this using the settings. And for creating water and foam effects, Cycles materials are already included. And you can use Advanced Ocean Modifier to make 3D models float on the ocean surface. Or have them interact in a short period of time then of course. As a result, you can make objects create waves and foam.
Overall this addon creates beautifully animated ocean waves with foam effects. However, it does not achieve a very high level of realism that we can see using Houdini, Bifrost or phoenix FD for that matter. But we can say that advanced ocean modifiers are doing a good job so far. Nebula generator Khaos Image Source: inspirationtuts. But now taking advantage of the enhance Eevee volumetric system it became much better.
Nebula generator also used some of the results and progress achieved by some of Blender community artists. And packaged them into one tool that can create nebulas easily.
There are a lot of parameters and settings you can change to adjust how the nebula looks. Like the color and textures of the gas or galactic dust, the number, brightness, and distribution of the stars which is automatically created using a particles system. Even though it is possible to create amazing looking nebulas in Blender using this addon, there is a problem yet to be completely solved which is rendering animations of those nebulas.
The problem is not in the addon itself but in the nature of how the volumetric system works. It has fast render times even at high resolutions. Also, a range of configuration options that allows you to change the color and shape of the nebula. In addition, by animating the parameters, the clouds can be made to appear as if they are moving. Khaos Khaos Image Source: inspirationtuts. With its assets and intuitive user interface menu, it provides the ability to procedurally add various particle effects including fire systems, smoke systems, dirt systems, and various particle debris such as glass, concrete, rocks, tree branches, dirt, metal shrapnel, rebar rods, wood pieces, and sparks!
The 3d asset database includes over 35 re-topologized 3d models and scans of common explosion debris you would find in the real world. The developers made it so you can select and add this explosion debris inside custom particle simulations to the scene automatically. You can render the debris fields out separately to composite them seamlessly with a VFX compositor like Nuke or other compositors.
Also, Khaos has preset materials to get different results Whether you want a dust blast or a fiery explosion. Once added to the scene you can adjust the settings further to get a more specific look if necessary. The custom-built fluid engine of flip fluids is based around the popular FLIP simulation technique that you can also find in other professional tools such as Houdini, Phoenix FD, Bifrost, and Mantaflow.
You can do a lot using flip fluids. For example, generating and simulating millions of foam, bubble, and spray particles to give a sense of realism to large bodies of water. Blender users can easily choose their machine configuration from recommended system requirements to high-end options, which suit all your project demands and will speed up your rendering process many times.
11 great Blender Addons for Simulation and Visual Effects
As long as you have a semi-strong background in the software you should be able to apply these to your workflow right away. Every simulation requires experimentation to get the look that you desire. The process is not as simple as pushing and pulling geometry like one does in standard 3D modeling. Explosions in the real world have a lot of random variation and systems within them. Because of this quality, one thing you should try to avoid is using only one particle system to get a desired look to a sim.
You can even create secondary and tertiary blasts making it seem like the first blast set off a chain reaction. The more concentrated parts of the fuel particle field will burn out slower, and the less concentrated parts will burn out faster.
This helps create a unique shape to your explosion too. You can also vary the lifetime of different particle systems as well to create interesting results. The KHAOS omnidirectional operator throws fuel in every direction, while the groundburst operator throws fuel up and out with a degree of control and the directional operator throws fuel in only one direction.
You can combine these operators to create a unique look to an explosion or simply create your own particle system for a simulation. Multiple fuel fields in a particle system create a more unique explosion shape 2. Increase Domain Resolution Divisions Use this technique for a larger scale looking explosion. Then bake with more high-resolution divisions once you like the general look and movement of your simulation to get more detail.
One of the main inputs that controls the way smoke is simulated in Blender is the size of the smoke domain. The smoke domain resolution size controls the number of cells Also called voxels computing the smoke movement inside of the domain cube.
Adding more domain resolution divisions to your domain cube does several things. First it increases the visible resolution of your smoke. Second, it gives the simulation a larger scale look Meaning given the original particle system you add the smoke movement and interaction will look like it belongs in a bigger environment. The smoke high resolution divisions attribute adds additional smaller scale details to the original smoke mesh using noise patterns over the original mesh You can increase the strength of this noise but I usually keep mine at 1.
Keep high resolution off until you like the behavior of your simulation and then re-simulate with high resolution once you like the behavior. In short, use a small number of domain resolution divisions to recreate smaller scale sims like a candle, and a larger number of domain resolution divisions to create larger scale fire and smoke explosions. Experiment with domain resolution divisions with the high resolution checkbox off, and once you like the behavior of your simulation crank up divisions accordingly to add more detail.
The largest scale smoke simulations I have simulated at domain resolution divisions and 2 high resolution divisions. For the smoke on the right we have the same resolution but have increased domain resolution divisions for larger scale looking simulation.
On the left we have less domain resolution divisions but more high resolution divisions for a smaller scale look. Whether you are going for photorealism or not, it is important to consider whether or not you want to add more debris to your blast to give a more violent and chaotic look. With my Khaos add-on for Blender you can add various debris fields to your scene with one click.
That said, you can also model debris in 3d and link them to a particle system yourself for a similar result. Some options for awesome debris you can add include glass, rocks, dirt pieces, wood, and metal shrapnel.
Quicktip: Render your debris systems separately so you can composite them with more control. With and without debris added 4. Particles can burn out fairly quickly when creating fiery blasts. While this can be great if you are trying to create a sudden explosion, you may want to create a slower burning look with lingering flames in some scenarios.
This technique, along with the use of lots of concentrated particles, can help create a fierier gasoline style explosion. One key to larger looking smoke simulation is smaller scale detail and bubbles within the mesh.
To recreate this look in blender you can add turbulence fields with a small amount of noise variation to push and pull the smoke in random directions over the course of the blast. I recommend keeping the strength from 10 — 20 on the turbulence but it depends on your simulation.
Turbulence created detailed smoke bubbles 6. The reason for this is that you often need to add glow and motion blur to blend the pixels in a more realistic manner. You can also keyframe the glow or glare over the course of the explosion so that it starts incredibly bright and then dies down as the flames burn out.
Although this does take more work, this method can offer that finishing touch to make your explosion look ready for a Hollywood blockbuster. With and without glow and slight motion blur added in compositing 7. That said, in this short piece I will give a few tips that you can apply right away in your work. First of all: I almost always export my simulations in the OpenEXR file format for more range in compositing. In addition to this I also render most things with the RGBA setting so that an alpha channel is in the output animation files, just in case I want to change the background later.
Make the volume sampling step size around 0. And remember to play with the smoke material density and flame brightness, color, and contrast as well. That said, they can be so satisfying when you get them right! Keep resetting that cache and see what cool explosion styles you can create. Experiment with the density of the smoke, the temperature, the vorticity, scale, and the ignition speed to get different smoke and fire behaviors. It features tons of real Blender projects built using the plugin and shows just how much you can do with explosions.

Where do addons go?
Khaos Ultimate Explosion Blender Add-On
When an addon is installed it can be hard to know where it actually gets installed. On windows, there are generally two locations with a third sometimes existing. However, for me, this has been created automatically in some way. Either way, there are the locations on Windows that is used for addons in Blender. For other platforms and more information on Blender's paths you can take a look in the manual.
Now that you know how to install add-ons and what pitfalls there are to look for if an addon does not install correctly, we can continue to look at some of the most common and useful ones. So these are the add-ons that I have found useful over the years of Blending. The list is 2. Some are built-in, some are free and others are paid addons. Some may be in alpha or beta stage. Modeling add-ons BoolTool How to get: Built-in This add-on adds a few shortcuts to quickly create boolean operations.
Select the boolean object and then shift select the base object. The operations are then done by holding ctrl and press one of the basic math operations on the Numpad. The only thing it does is that it adds some functionality to the F key that improves the modeling workflow.
It adds a few functions to the "F" key. You can create a face from a selected corner vertex and fill faces way quicker than without this addon. Watch this short video on how it works. It works pretty much the same in 2. Scatter Objects How to get: Built-in This addon makes it easy to scatter objects in an area based on a grease pencil stroke. Very handy when you want to add some debris or scatter some rocks around an area. Select the objects you want to scatter, then select a target object last.
Hit F3 or space and search for "scatter". Start the operation and paint on the target object. Hit enter when done. Extra settings are available in the Active Tool tab in the properties panel.
Simple Lattice How to get: Github add-on page free version Just like bool tool enhances the boolean workflow, simple lattice improves the lattice workflow. The addon adds a menu entry in the object menu in object mode and in the mesh menu in edit mode. When selecting either of them a lattice will be created around the selection, adding a lattice modifier to the object. It even works with Blenders new multi-edit support. It will add a lattice modifier to any object that is fully or partially selected and add a lattice modifier to that.
Then it will also add a vertex group for the selected geometry in edit mode. Three point arch How to get: Github add-on page Free version This addon adds a tool that makes you able to create quick arches. It is found in the N-panel in the 3D view under the create tab. Hold ctrl to snap to vertex then just click three times following the gizmos visuals. A pillow will be added with everything needed to simulate it and the simulation will even start, making a pillow within a second or so.
From there you just have to adjust it to your needs. It is really impressive. Perfect for anyone who does not work with characters from day to day but still occasionally needs one.
