Unity Issue Tracker - Crash on various stack traces when using Texture2D.CreateExternalTexture() while rendering

As expained in the docs at https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Texture2D.CreateExternalTexture.html you need to pass a VkImage* (thus a pointer to a VkImage. E.g. changing the script to the following fixes the issue locally for me on vulkan: IntPtr vkImageToRef = nativeTexture.image; IntPtr imageRefStar = new IntPtr(&vkImageToRef); texture = Texture2D.CreateExternalTexture(width, height, TextureFormat.RGBA32, false, true, imageRefStar); This can also be found on the forums: https://discussions.unity.com/t/error-when-importing-textures-using-vulkan-native-rendering-plugin/898563 As for the crash when using other APIs than Vulkan. This is because you are passing in an invalid type. When using DirectX you have to pass in a valid DirectX texture to CreateExternalTexture not a Vulkan image. See the docs referenced above for the correct usage of the CreateExternalTexture function on all graphics APIs.

Reproduction steps:
1. Open the attached “repro_IN-101754“ project
2. Open the “Assets/Scenes/SampleScene.unity“ Scene
3. Enter the Play Mode
4. Observe the crash

Reproducible with: 2023.3.0a15, 6000.0.49f1, 6000.1.4f1, 6000.2.0b2
Not reproducible with: 2022.3.63f1, 2023.2.0a20, 2023.3.0a14

Reproducible on: Windows 10 (22H2)
Not reproducible on: macOS Sequoia 15.3 (M2 Ultra)

Notes:

Reproducible in Player
Reproducible on DirectX11, DirectX12, Vulkan, and OpenGL ES 3.2
Not reproducible on Metal
“DllNotFoundException: NativePlugin assembly:<unknown assembly> type:<unknown type> member:(null) VulkanTextureImporter.Update () (at Assets/Scripts/VulkanTextureImporter.cs:68)“ error is thrown when using Metal on a reproducible-with Editor version, or using any other graphics API on a non-reproducible Editor version
