Welcome to the forum.

Yes, SARndbox 2.8 is the recommended version.

In “I can’t make it rain”, you mention “1” and “2” keys. Did you assign these through the configuration file or the on-screen pop-ups? I recommend the on-screen assignment as a way to get immediate feedback whether the key assignment worked. Try adding “3” and “4” as more rain/drain keys through the on-screen assignment.

Once you have the keyboard rain/drain working, the rain hand is a matter of using the right hand shape.

Let me know if this works for you. There are other things to try.

@viagoito4 My first guess is that you are editing a different file than the sandbox is reading. How many files does the locate SurfaceAddWaterColor.fs command show you?

I don’t know the details of your configuration, but I assume the file read by your sandbox software has a path like “/home/viagoito4/src/SARndbox-2.8.1/share/SARndbox-2.8.1/Shaders/SurfaceAddWaterColor.fs”.

We switch between full-color and white maps for the same reason, using the control pipe. This Switch texture water to lava post describes how to change colors. For white, create a .cpt file with the following values.

-25.00 255 255 255
25.0 255 255 255

AFAICT, “Pause Topography” is not available for assignment to a key via the configuration files, but I could be wrong. If you are comfortable patching C++ source, the following diff will add a “pauseUpdates” control pipe command. This will toggle screen updates using the same algortihm the assigned key uses.

I suspect the problem is with your Kinect power supply/USB adapter. Your output from lsusb shows one Kinect device: “Motor”.

Bus 003 Device 019: ID 045e:02b0 Microsoft Corp. Xbox NUI Motor
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

There should be two more USB endpoints for the Kinect. Our development v.1414 has the following three devices connected via USB.

Bus 001 Device 010: ID 045e:02ae Microsoft Corp. Xbox NUI Camera
Bus 001 Device 008: ID 045e:02b0 Microsoft Corp. Xbox NUI Motor
Bus 001 Device 009: ID 045e:02ad Microsoft Corp. Xbox NUI Audio
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The error you see with cd ~/src means you probably need to start from Step 3. The src directory is created by Build-Ubuntu.sh.

When I do “make” it says no such file or directory

This is also because the output from Step 3 cannot be found.

Details:
Ubuntu 18.04.6LTS
NVIDI GeForceRTX2060/PCIe/SSE2

Did you get back to Ubuntu 18.04.6LTS after the update? Or is that what you expect to still be installed?

This is important because the “Software Installation” instructions do not work with later versions of Ubuntu.

I suspect there is a problem with the keybinding. You should have two keys: “Capture” (measure disc) and “Capture Background” (reset sand heights). After selecting “Capture”, a window will pop up; press a different key to bind that second key to “Capture Background”.

The “and a half” method is that water flows out of the sandbox at its edges. Shaping the sand so that the box edges are low points in the topography will let the water escape the sandbox.

4/5

Quoting from the help output: “-evr <evaporation rate> Water evaporation rate in cm/s”. This can set a constant evaporation rate to remove water over time, but is fixed during the run of SARndbox.
