Cloth
Today I tried on some cloth simulation.
These are the two tutorial links:

Firstly, I went to the Mixamo website to download the free character with animation. I downloaded it as an FBX file and I'll import it to Houdini. To group the animation together and cleaning things up, I'll first select the body and a "body_geo" with a set of nodes will pop up. I'll go to the take list. I'll merge the mixamo_com in the take list to the main and delete the other nodes in the take list except the main. So now, my animation will work just fine. To resize it, I'll first select the body and go to the Modify tab > extract. After I do so, an "object_merge" will appear. I'll rename that node to "body" and inside that geo, I'll put in a transform node and scale it down to 0.1.
I'll do the same for the other 3 parts which is the hair, left eye and right eye by duplicating the "body" node 3 more times. Next, we'll export the geometry by creating a ROP output driver in each of the node and render.
So now everything is completed, I'll go and create a new file and import in the geometry that I just rendered. I'll now drop down a mantra surface and change the specular color to something dark. After that, when we downloaded the model down using FBX file and extract it for the first time, they'll have some default material coming together. So I'll assign that material with it.
I'll now start to create the skirt for my character. Firstly, I'll start by creating a circle and resize it. Then I'll go and do a polyextrude and do some alter to the settings. In order to achieve more details, I'll put in a subdivide for the skirt polygon. Then I'll adjust the radius and center accordingly.
After that, I'll color the skirt by using a mantrasurface.
So now, I'll go to the cloth tab and select the body, then click on the cloth body collider. Then I'll select the skirt and cloth on cloth object. So now the simulation is created. However, the skirt is not attach with the body and it looks weird. So I'll use the attach to body tool to attach both together. I'll select only the top part of the skirt.
So now the cloth simulation of the skirt is done. I enjoyed doing this tutorial as I find it quite fun to help the character to create some clothes for her. I've also learned how to use basic shapes and gradually create out some cloth.

Particles Spray On Waves
I tried on another tutorials whereby we can create particles spray on waves.
This is the link for the tutorial:

For this tutorial, I'll first have to create a grid, changing it to a nurbs. Then I'll apply a soft transform in the middle of the grid points and adjust it.
I'll then add in a mountain node and created out a network box to clean up my network. Next, I'll go and create three curves that will be used as an isobars.
I'll apply a transform after the merge node to do the keyframing for the isobars to animate and move.
After that, I'll add in a convert node after the mountain to convert it into a polygon. Then, for the other side of the transform node, I'll add in a color node and make it red color. Then I'll combine both nodes using an attribtransfer.
I'll now group the points together by creating a group node. In the group node, I'll create an expression of $CB < 0.8
I'll then add in a "popnetwork" and dive inside to create a source. Then I'll adjust some of the settings and this is the final result for this exercise.
