That is the nature of reflection and refraction. The colors from the environment are calculated through the surface. If you don't want to see that you can turn it off at the material level. Dive into the basicliquid material and locate the Settings tab. Set the value for Inside IOR to 1.0.
The IOR or Index of Refraction is a mathematical light bending algorithm used to simulate the light passing through a surface. You can emulate various materials from water to diamonds by simply setting the appropriate IOR.

Have you tried using the latest version of Houdini? It looks like you are installing version H13.
Try posting your Mac hardware specs or review the system requirements.
Houdini 15.5 does not work with most Mac hardware. Especially low-end machines.

Attributes can be added to the crowd system inside the CrowdSource node. Just insert an AttributeWrangle before the OUT node and type in your new attributes.
You can then reference those attributes inside the CrowdSim network. For example change the CrowdTrigger (orange node) type to Custom VEX Expression and the node essentially becomes a wrangle where you can examine any attribute and use logic to set the @itrigger as necessary.

You just ALT-Click on the word Color next to any color swatch. This will add a keyframe for that current color at the current time in the timeline. Change to a new frame and then pick a new color, then ALT-CLICK again to lock in that keyframe.
The numeric RGB color fields will turn GREEN to indicate there is a keyframe on them.

That is what the path inside the chop() function is for. The path specifies where the data is coming from (i.e. your chop network output). Where you paste the line of code indicates where the data is going to. Try pasting your chop() function in the Const. Birth Rate field.
To determine the path for your case, you have to have a CHOP network in your scene. When you start typing the word chop( and you get to the typing of the quote character ", Houdini will prompt you with a list of possible sources to form the bread-crumb trail to your data. Each time you type a new slash character / you will get a new list possible paths you can take at that time.
NOTE: The channel name will not automatically appear in a list, you have to know it and type it manually to complete the path. In my example path, the channel name happened to be kick. Houdini defaults to a name called chan0 for mono sources and a pair chan0, chan1 for a stereo image. So you can use the left channel of a song to control one parameter and the right channel to control another.
Typically audio will import in the range of -1 to 1. So I follow up a file import with a limit and envelope. This will change your audio amplitude range into the value of 0-1. Then you can just use a fit01 along with the chop() to remap the audio value into a usable range for whatever target field you like. (i.e. 0-360, 0-1000, etc…)
A thousand particles are emitted when the beat is loud, less as the amplitude drops off over time.

You can fetch data from a CHOP network using the chop function.
I put together a short video on how to leverage the amplitude from a sound wave to drive position along path but you may be able to modify it to drive particle birth rate.

You can do this in passes. For instance use a ROP Output Driver to export the Cubo as a .bgeo.sc sequence. Then bring that sequence back in as a Rigid Collider for the cloth. Make sure to set the static object to Use Deforming Geometry and up the volume based Uniform Divisions.

You may want to add another attribute to the system just for monitoring for your special case. You need the popseek to look at that attribute and change the way it seeks based upon that flag. So when you transition to climbing set the flag on the new attribute and then on the next frame the popseek can review that attribute. You could even come up with a switch that monitors the attribute. When it is set an alternate popseeksteer is used instead of the walking one.

You do have to specify the full path and filename, not just the path. Also the full path should not have any spaces in the path. Make sure your user name for the system does not have any strange ASCII characters in it.
I have attached the example 08_02.bclip and .cmd files referenced in the video. Just use the .bclip to continue the video even if you can not get the convert to work.

A FEM Solid won't interact with a cloth just using shelf tools.
That is the nature of the system as it stands at version 15.5. If you want your cloth to interact with the sphere don't define the sphere as a Solid object, define it as a Rigid Body Collider.

If you can, post your HIP file or an example file that demonstrates the problem.
Have you inspected the collisions meshes? Most problems are because the collision representation of the actual geometry has holes in it, thus not colliding.

That is what the UV Layout node is for. It allows you to dial in your UVs into a single tile 0-1 space or across several UDIMs. Make sure the display flag is set then press SPACE-5 over the viewport to see the UV layout. Drop down a ROP Output Driver after that to write out your object with the UVs.

It is not really better, just another option. Try turning it on an off, you'll see the difference.
When the isooffset is off the fracture thinks of the shape as essentially being hollow so in this case of the sphere each fracture will travel to the center and form a spike. When the isooffset is on the fracture will think of it as a solid shape and create fracture chunks inside the volume interior as well.
