Welcome to a new Houdini Course: Ash Disintegration

This effect is achieved through a method which is essentially layering two different simulations that run at the same time.

We will start by fracturing the rose geometry, using a custom fracture method, which combines the common voronoi workflow with the boolean fracturing method.

After we fracture the geometry, we are going to run the first simulation which will operate on our fractured pieces, and we are going to create a custom solver that drives this simulation.

And then on top of this simulation we will run a second simulation that will make each individual fractured piece turn into even smaller pieces that disappear entirely over time.

So essentially, the geoemtry will first disintegrate into big pieces, and then these pieces will disintegrate into even smaller pieces, and we will be able to control this transition between simulations seamlessly.

Rendering

After we set up all of the geometry and effects, we will render a few passes using Redshift. In this section I also go over how to export custom AOVs such as custom textures and houdini point attributes.

Nuke Compositing

Then we will bring everything inside of Nuke to create the final result.

Here I go over how to leverage the AOVs that we generated to have complete control over all aspects of the final look.

Downloads

You will have all the geometry required included with the downloads. Everything else that I couldn't include (like megascans texture) you will be able to find by using the links provided in the links notepad.

The download archive also include the completed Houdini project file (ver. 19.0.589)

Course just finished.
Another excellent content with interesting solutions explained in a very clear way.
You confirm yourself as an excellent teacher and I will certainly follow you in your next projects.
I hope you will want to consider the idea of using Karma in the future which now seems stable and promising.

It would be really helpful if you could make compositing videos for Natron. Like for example the Ultra Instinct aura; there seems to be no DB Natron artists.

seems like the course is no longer available in your page :(

Hello Voxyde! I'm doing my TFG from the animation & VFX degree and this tutorial is perfect for one of the shots where a photo burns. There's any discount for students? This tutorial would help me a lot but I don"t have the money for it. Thanks in advance!

Hello, this was a great course! Thank you for instructing it clearly.

I had a question on how to make some of the pieces on the left of the flower start to disintegrate sooner and not be static during most of the simulation. I tried messing around with scatter, but still had pieces not simulating until close to the end.

Any help is much appreciated, thank you!

What if people want to use Mantra to render the sequence instead of RS? I think RS isn't a good idea for regular beginners.

[ps]

I bought this course at CGCircuit but where I can download the rose object file..?

Hi, I have paid for this course, when I click the pay button, but the Gumroad web page stops and nothing responds, please help me, thanks!

Just call it what it actually is… Blip simulation
