How to resolve the errors related to .rendertexture files and image2car package?

Omniverse Core Platform
1

When I open my USD file in USD Composer, the console will report the errors below:

2025-08-26 08:46:11  [Error] [carb.imaging.plugin] createimage: Invalid image format extension: .rendertexture
2025-08-26 08:46:11  [Error] [gpu.foundation.plugin] Failed to load texture C:\TST0519_test\Materials\Left_Sideview_Mirror\Sideview Mirror Left.renderTexture (reason: 3)
2025-08-26 08:47:07  [Error] [carb.imaging.plugin] createimage: Invalid image format extension: .rendertexture
2025-08-26 08:47:07  [Error] [gpu.foundation.plugin] Failed to load texture C:\TST0519_test\Materials\Mid_Mirror\Mid Mirror.renderTexture (reason: 3)
2025-08-26 08:47:11  [Error] [carb.imaging.plugin] createimage: Invalid image format extension: .rendertexture
2025-08-26 08:47:11  [Error] [gpu.foundation.plugin] Failed to load texture C:\TST0519_test\Materials\Right_Sideview_Mirror\Sideview Mirror Right.renderTexture (reason: 3)

Then, I wanted to make use of the image2car extension to run the file by adding the vehicle’s image. I first downloaded the image2car extension and enabled it, then added the vehicle’s image. When I pressed the play button, the situation was as shown in the video—it seemed like the vehicle had no trajectory and was falling freely.

The console also reported the following errors:

2025-08-26 08:49:49  [Error] [omni.physx.plugin] PhysX Vehicle: vehicle is being created but the stage has no matching physics scene prim with PhysxVehicleContextAPI applied. Default values are being used but might not match the required setup for the vehicle.
2025-08-26 08:49:49  [Error] [omni.physx.plugin]

Please tell me how to resolve them, thank you.

@1057533704 i am just another user but wanted to make a few points based on what’s mentioned:

  1. Create 2022.3.3 has reached EOL and is several years old; some of the support for these extensions may no longer be available/supported. the latest kit app is 108, where you can grab from github
    GitHub - NVIDIA-Omniverse/kit-app-template: Omniverse Kit App Template
    to the same point, OV Launcher will be deprecated by Oct 1st, so it may be a good idea to make the transition at some point in the near future.

  2. at some point, those AI extensions ended up being consolidated into Ganverse3D or AiToolbox extension. i’ve not used any of the AI extensions so i can’t say with 100% whether you can find image2car in the latest kit. that said, there are other photo to mesh extensions (such as ALPHA3D) that you can look into via the legacy tool found in Legacy Tools for Omniverse Launcher | NVIDIA Developer . if you are using 2022.3.3 primarily with the intent to use these extensions, you can ignore the first two points.

  3. regarding the issue with the free-fall mesh, you will probably want to create a physics scene prim via Create > Physics > Physics Scene. however, i have to reiterate that i have not used these AI extensions in the past, so this suggestion is strictly based off of the console message.

Yes, I’m sorry to say that this Version of the software is very very old. Nothing of that age is guaranteed to work now. Please install the latest version of the kit template 108.

Please uninstall and uninstall Launcher and purge.

Then install from here

Thank you for your reply. Regarding 3, actually I have created the PhysicsScene for my Instance, which is shown in the figure below:

So I don’t know what’s wrong with it. And this USD file works well on the computer of my colleague.

Regarding using Omniverse Kit App Template, I have no idea about ALPHA3D, maybe I should go deeper into it.

Please uninstall this old version and uninstall Launcher and purge.
