Showstopper problem trying Omniverse tutorial

[JonJingleberry]

So, I thought I’d try the demo for omniverse (Cesium for Omniverse Quickstart – Cesium), but also running into no love :-(. Step 1.6 in the tutorial shows the omniverse plugin 0.3.0 should be ok. However, in reality, I’m seeing a red-triangle with exclamation point, which seems like it is trying to say it is some problem in loading (attached)–no place to explain what the icon means. The omniverse plugin for USD seems to be loaded fine. I can’t seem to proceed with the demo without this.

Hi Jonathan - thanks for reaching out.

Could you check if there are any errors in the console?

Also could you post more details about your environment - OS, GPU, and Create version?

[JonJingleberry]

Hi Sean, thanks for checking. I am using the Omniverse app with Create v 2022.3.3, Windows 11 Home build 22621.1413, 11th Gen Intel(R) Core™ i9-11900H, with NVIDIA GeForce RTX 3050 Ti Laptop GPU.

I tried removing the cesium extensions from the exts folder after disabling the USD extension from the Extensions window. When I opened Create, I got this message in the Console:

2023-03-23 23:36:24 [Warning] [omni.ext.plugin] [ext: omni.kit.scripting-104.2.2] 'c:/users/kayej/appdata/local/ov/pkg/create-2022.3.3/extscache/omni.kit.scripting-104.2.2+104.2.wx64.r.cp37/bin' in '[[native.plugin]]' was not found.

For the fun of it, I removed omni.kit.scripting-104.2.2 and then Create would not launch, so I put it back. I also then put the 2 cesium folders from version 0.3.0 into place in Documents\Kit\Shared\exts, and got these 3 messages when I launched Create:

Then I went into Extensions and tried to activate the 2 Cesium plugins. Back in the console, I got the following messages:

2023-03-23 23:45:30  [Error] [carb] loadPlugin: Library path doesn't exist: c:/users/kayej/appdata/local/ov/data/kit/create.next/2022.3/exts/3/cesium.omniverse-0.3.0+wx64.r.cp37/bin/cesium.omniverse.plugin.dll

I tried to uninstall Create app from the launcher and from Windows Add Programs, but for the life of me I can’t see where to uninstall it. I tried uninstalling the Omniverse launcher, but when I reinstalled that, the Create app was ready to launch. I am reluctant to uninstall other NVIDIA apps on my system because I do have an NVIDIA graphics card and I might mess stuff up there.

I also tried installing the Cesium plugins from the Extensions window directly (i.e., not putting the files in the Documents folder as instructed in the tutorial). I got more errors than before.

Thanks for any help!

[adam_morris]

Hi Jon, sorry to see that you’re having issues. Let’s get you to a clean install of Create.

@JonJingleberry

I tried to uninstall Create app from the launcher and from Windows Add Programs, but for the life of me I can’t see where to uninstall it.

To uninstall Create you can click the “hamburger menu” next to the launch button in the Omniverse Launcher. It’s the button my mouse is hovering over in the screenshot below.

That will open a little menu and you can click “Settings” which will open the screen where you can uninstall Create. Go ahead and uninstall it, then before you reinstall, make sure the “$HOME/Documents/Kit/shared/exts/” path is empty.

Once you do that, run Create once just to verify everything is working again. Then, close Create, and reinstall Cesium for Omniverse to the “Documents/Kit/shared/exts/” path and run Create again. If you’re still having issues please share the errors you’re having in the console at that time.

Would love to try this out, but I’m experiencing the same issue. Create 2022.3.3 …

[JonJingleberry]

Hi Adam, thanks for the help, just to close the loop I was able to uninstall Create but when reinstalling, just got the same error about the id already being used. Unfortunately, I have to move on so I can’t spend more time on this.

-jonathan
BTW FYI trying to uninstall the Ominverse Launcher is a bear (nothing to do with Cesium) – going through typical Windows install tells me it’s no longer there, but on my computer reboot, hey-yo! there it pops up. I turned off the app to launch when Windows starts, so I’m pretending that I really uninstalled it, but I know deep down it is still lurking. Problem I have deleting folders/files in my NVIDIA folder is I don’t know which folders/files are needed for my graphics driver and its gui.

[sean_lilley]

Hi @vsnappy @JonJingleberry, we think we know the problem here. If you tried installing Cesium for Omniverse from the extensions window without first installing the release zip it won’t work. Make sure to follow the instructions in the Cesium for Omniverse Quickstart by downloading the release zip and copying the extensions into Documents/Kit/Shared/exts.

If done correctly, you should see the image on the right

Installed from repo	Installed from release zip

The reason that installing from repo doesn’t work is because our extension consists of C++ code that is compiled into several DLLs. We don’t include prebuilt DLLs in our github source tree, only in the release zip.

We’ll think about how to improve this workflow so it doesn’t cause confusion for others. Hopefully this helps get you up and running.

[vsnappy]

Thanks Sean,

That helped immensely. I did need to track down the previous repo based install and remove it from my /AppData/Local/ov/data/Kit/Create.Next/2022.3/exts/3 directory.

I think the confusion is based on the “Install” button in the Omniverse Extensions browser and no mention of the Quickstart or need to use the zip files in the Extensions description presented in the Omniverse Extensions browser.

[sean_lilley]

@vsnappy glad to hear it helped. And thanks for posting those extra steps. I think that explains the “Extension with the same id is already registered” error that @JonJingleberry was running into.

I agree that it’s confusing and we’re seeing what changes we can make for how Cesium for Omniverse appears in the extension registry.

[sean_lilley]

Just to give an update here, the reason Cesium for Omniverse appears in the extension registry as a community extension is because we were using the omniverse-kit-extension tag. Nvidia automatically scans GitHub for all repos with that tag and adds them as community extensions.

We’ve since removed the tag and are waiting for the extension registry to be updated. Once that happens you’ll no longer see the community extension; the extension will only appear if you install it according to the Cesium for Omniverse Quickstart.

[sean_lilley]

This issue is now fixed. Cesium for Omniverse no longer appears as a community extension.

[gilmar_guzman]

I have followed all the steps and I still have the error, are you in maintenance to fix the problem? because omniverse still recognizes the pluggin as community.

[sean_lilley]

Hi Gilmar - It looks like a different issue. The extension shows up as a user extension (see image).

Could you double check that you’re following the steps in the Quick Start correctly? Make sure to tick the Autoload box for the Cesium for Omniverse extension and then restart.

You shouldn’t need to do anything with Cesium for Omniverse USD Plugins, that will be enabled automatically.

[dbs4261]

I am also running into this issue. I cannot enable autoload because omniverse failed to solve all extension dependencies. I have fully removed omniverse and followed the quick start guide again without success. I am running on Ubuntu 22.04 with the 525.125 driver.

[sean_lilley]

Hi @dbs4261 - I see you’re running Create 2022.3.3.

Cesium for Omniverse v0.8.0 requires USD Composer 2023.1.0 or above.

[dbs4261]

Good catch, that worked! Might be worth updating the quick-start to mention you have to go into the beta tab tog et that version of create.

[sean_lilley]

Yes! We’ll update the getting started guided shortly.

[Nikolaos_Lavdakis]

Greetings. I have followed all the steps from quickstart quide given above, i autoloaded cesium for omniverse nevertheless i get the error as well. (windows 11 on NVIDIA GeForce RTX 3050)

@Nikolaos_Lavdakis For some reason Omniverse can’t locate CesiumUsdSchemas.dll. Could you try placing the extension in a different folder without special characters? It’s possible the Unicode characters in Έγγραφα is causing the problem. Let’s see what happens and then go from there.

[Nikolaos_Lavdakis]

Thank you! I had my os in my native language and apparently omniverse couldnt recognise the name of documents’ folder in greek.
