Object Field with large preview image.

If you can get a preview image in a Texture/Texture2D, you can do one of the following for your UI Toolkit implementation:

1. Create a

VisualElement

and set

style.backgroundImage

to the texture:

Code (CSharp):

1. Texture2D previewTexture = ...;
2. VisualElement ve = new VisualElement { ... };
3. ve.style.backgroundImage = previewTexture;

or use an

Image

and set its

image

to the texture:

Code (CSharp):

1. Texture2D previewTexture = ...;
2. Image im = new Image { image = previewTexture };

 

Oh yeah. So you could do a couple of things, among those:

1. Create an InspectorElement that will hold:
i. a PropertyField (that you bind to a property holding your asset)
ii. a VisualElement of your choice (as mentioned in my previous reply)
Then, write a callback that will be called when the property's value changes, so you will be able to update the element's backgroundImage or image when called. You specify that callback with PropertyField.RegisterValueChangeCallback().

2. Write a custom property drawer (assuming you want to use your field in the inspector), that could be used for a specific attribute for a specific data type; that would let the editor take care of creating an InspectorElement for you and mostly everything else if you provide a binding path to your property (that holds the asset).
