Peeling a wall hasn't been easier, a more upgraded method where the edges tend to shrink and curl compared to the normal peeling effect.
Tool's features:
- currently working on plane surfaces, while can be applied to organic shapes but still some things are to be developed.
- normal things like defining the mesh resolution and pieces size.
- The edges of the paint are fi...

A great tool to cover any surface with snow.
Tool's features:
- Covering was achieved by using "Mask by feature" you can specify the snow blowing direction and what parts are blocked by the model "in the shadow".
- A nice cracking pattern through the snow.
- A layer of randomly scattered snow flakes.
- Falling snow particle system.&nb...

Remember the Recursive Fracturing tool, well this is the same but done with vellum.
Features:
- Activation stage, cloth will freeze until it's activated.
- Multiple fracturing stages (two in my scene but you can push it more).
- Activation and fracturing are triggered once the points are inside a group,...

The original tool can be found here...
What's been updated:
- Much faster setup (keep an eye on fps and performance monitor), normally the clouds are static an no shadows need to interact with them, if that's the case then the old setup is enough since you are going to bake it once. 2021-05-12 12:06:31 +0000 UTC View Post
Update:
- Twisting the uv to create a whirlpool like effect has been added.
- and why no body ever told me that I didnt uploaded the old setup 🤦♂️
A simple setup that help you cheat a suction effect performed on the uv channel, features:
- suction center, it has some limitations when it's near the edge of the uv.
- suction direction, but mostly inward.
Adding more details to your smoke sometimes can be tricky and a straight forward Turbulence is not the answer, so in an attempt to bring this to the next level I started looking for ways to mask gas (Turbulence, Confinement, Disturb) to a certain areas based on speed and distance as you can see in the video, and while it's not a Hollywood level but it's a step on the right direction. ...

Bricks builder or as I like to call it "Brickfy" is a new tool that takes advantage of the amazing Chain sop introduced in Houdini 18.5 to convert any object "in theory" into stacked bricks.
Tool's features:
- Automatically divide and prepare any object according to the brick size.
- Distribute bricks "any kind of models" randomly, cycle or by percentage.
- Ra...

My take on water explosion, it's heavily inspired by Graham Matthew's setup.
Tool's feature:
- main plash done with flip.
- secondary "dump particles"
- the particles will conform to the water surface once in range.
- Alpha by age and radial range at the base, so we wont see those particles at the edge of the flip container.
Rendered with redshift and GI was ...

In an attempt to mimic how dirt in water behaves, I created this simple setup Using different flip densities, which gave an acceptable results.
If you look closer you can see that the heavier ones are not settled down and they are still fighting (jittering) at the bottom as if there is some kind of boiling happening there.

The anatomy of this setup goes like:
- Box: Sadly still RBD doesn't interact quite well with vellum so I had to fake the rigidity of the box by using Struts constraint with some stiffness,
- Wires: I went with the hair constraints since I can control the bend.
- Cloth: I had to create a custom force to stop it from collapsing and to give that air resistance feel.
I...

Getting my self familiar with grain solver doing some stress and stability tests, I thought it might be helpful to share. As you can see I added some straws but they don't rotate as what you would expect following the stream, instead you'll need to use RBD Grains.
I tried creating the same effect with vellum but failed, the isolated grains keep jumping here and there, and also ...

Skip to the 20s to see the tool in action and how does it function, it was based on the previous fireworks tool but with custom explosion shapes, so you will expect the same features but with some more:

- If you shape already has colors then it will use tho...

The most ultimate guide to redshift proxy, instancing, timeshifting rs sequence, not sure if I covered everything but what happened is that last year I faced a lot of scenarios

Update 29-09-20:
In the previous setup I built the curve orientation manually, and I figured out that Houdini introduced a "Orientalongcurve" sop that will calculate that for you "Roll, Pitch, Yaw", so I introduced some controllers since it can be controlled by attributes. I thought of posting it here since it might help someone ;)

I was inspired by David Ferreira work that was featured on Houdini Hive 2020, so I thought of utilizing the flow field I created earlier this month:
by mixing two methods the gradient and the curve guided fields but in a simpler way. And surprisingly it ended up well, I tried a couple of ...

A nice trick that will allow you to up res an already simmed vellum hair, in my example I simmed only 350 hairs and boosted them to 5000.
The steps are:
- Generating the low res strands.
- Create the vellum simulation.
- Generate the high res one and use the low res as a guide.
Well it sounds complex but believe me it's a strait forward setup, also it was the first...

Remember the old balloon setup, well it got improved:

- new shaders (Redshift).
- new balloon model with a tie now ;)
Still cleaning it, I'd love to blow them up but it's out of my knowledge at this stage, already planned.

In 3ds max it's a matter of hitting a button, well not in Houdini it had to be difficult, but dont forget that it's procedural so if you mesh is deforming you'll get a deforming line as well ;)
One thing to mention is that this method might produce overlapping curves, so just add a delete sop to clean it out.
