Pointinstancer animation

Omniverse Core Platform OpenUSD
1

I implemented numpy data as a vector with color and direction using point instancer.
Afterwards, I want to use timeline to make this vector change over time, but it doesn’t change when playing.
How can I animate data changes over time in Omniverse? (USD Composer 2023.2.5)
Of course, I have all the numpy data according to timecode.

Hi and welcome to the forum. Ok let me ask and expert how to do this.

However, in the meantime you are using the version old version on the launcher system. It is now Legacy Software which are not updating and do not recommend. Honestly, I would just uninstall it. Everything we are doing is moving to simple, free downloads that do not require a log in at all.

All of our code is moving off Launcher and into GitHub and our own NGC website. If you are launching Composer for example, just find the install path and run the “omni.create.bat” file. Same thing with Isaac Sim, just go find the installation path and find “isaac-sim.selector.bat”. You can even make shortcuts on your desktop. However, just in doing so, you are already using the older versions, that we are no longer updating on Launcher.

To Uninstall the Omniverse Launcher on Windows, follow these instructions:

  1. Exit all kit apps

  2. Close the Launcher interface

  3. Right click on the “Green Launcher icon” down in the bottom right corner of the system tray and click “Exit”

  4. Start the “Add / Remove Programs” system for and select “Nvidia Omniverse Launcher”. Uninstall it.

  5. Start “Task Manager” and go to the “Details” tab. List by the “Name” column

  6. Look for all processes running that start with “omni” with a green icon. These are Omniverse processes. If you have none running, ignore this.

  7. Right click on each one of them and use the “End Task”. If you have none running, ignore this.

  8. Delete ALL of following folders, if you find them:
    c:/users/USER/appdata/local/ov
    c:/users/USER/appdata/local/omniverse-launcher-updater
    c:/users/USER/appdata/roaming/omni-launcher
    c:/users/USER/.nvidia-omniverse
    c:/users/USER/documents/kit
    c:/users/USER/documents/omniverse

  9. Restart your computer

For the new Kit versions, you have to use our “kit app template”. You have to do a small amount of building to use it, because we are moving to a developer focus, but it is easy.

Follow these instructions:

1. Download "git" from https://git-scm.com/downloads
2. Start a windows command console by using running "cmd" from the Windows Start menu
3. Navigate to the root of c: or d: drive. Example "cd\"
4. Copy and run "git clone https://github.com/NVIDIA-Omniverse/kit-app-template.git"
5. run "cd kit-app-template"
6. run "repo template new"
7. select the “USD Composer” template 
8. run "repo build"
9. run "repo launch"

I just heard back from the engineers. They said that we only support up to 4D vectors.
