I want to generate two preview images for these two objects.

I tried to run the following code
RuntimePreviewGenerator.GenerateModelPreview
But that return result is null

Can this plugin work within the ui?

RuntimePreviewGenerator.BackgroundColor = Color.clear; //new Color(1, 1, 1, 0); //new Color(0.3f, 0.3f, 0.3f, 0f) ;
tex = RuntimePreviewGenerator.GenerateModelPreview(model.transform ,256,256);
image.texture = tex; // RawImage

Thanks

Hi, when using your script in one of my editor scripts I get the following error when trying to save as PNG:

UnityException: Texture '' is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings.
CreateAssetBundles.SaveTextureToFile (UnityEngine.Texture2D texture, System.String filename) (at Assets/Editor/CreateAssetBundles.cs:37)
CreateAssetBundles.BuildAllAssetBundlesiOS () (at Assets/Editor/CreateAssetBundles.cs:29)

Trying to generate a preview on a simple Unlit/Transparent material on a primitive Quad.

Issue occurs regardless if a render pipeline was set or not.
Tried tweaking player settings with no luck.

Preview Generator configuration:
RuntimePreviewGenerator.PreviewRenderCamera = null;
RuntimePreviewGenerator.PreviewDirection = Vector3.forward;
RuntimePreviewGenerator.BackgroundColor = new Color(1, 1, 1, 0); // Also occurs using Color.clear and a black background;
RuntimePreviewGenerator.Padding = 0;
RuntimePreviewGenerator.OrthographicMode = true;
RuntimePreviewGenerator.MarkTextureNonReadable = false;

Previews work fine in editor, but Android builds using OpenGLES3 seem to ignore transparency on textures. On Vulkan this works correctly, but the platforms I want to support do not support Vulkan.

Specs:

• Unity version: 2019.4.9f1
• Platform: Android
• Device: Samsung Galaxy S9+, Android 9 (Pie)
• How did you download the plugin: Package Manager: v1.0.0. Using the Asset Store version shows the same result.

Additional info:
Minimum API Level: 26, Android 8 (Oreo)
Target API Level: 30

I created an object with the following hierarchy:

And the following view:

But the following is previewed:

Is there any option to make it work with UI items?

Is supersampling or antialiasing available

When render a prefab with Particle System ,the bounds is too larger which make camera too far away ,can't get the true thumbnail.

Unity version: 2019.4.7f1

Imported Runtime Preview Generator package.

Configured runtime preview generator, set background color to Color.clear, also tried new Color(0, 0, 0, 0);

In editor this works, but an Android build shows the resulting texture has a black backgorund fully opaque.

We use the alpha of the preview texture to assist us with raycasting and selecting objects in the scene using Google Cardboard.
I have tried OpenGLES3 and Vulkan graphics API but they show the same result.

Any help would be appreciated.
