Editor.RenderStaticPreview

Parameters

Returns

Texture2D Generated texture or null.

Description

Override this method if you want to render a static preview.

When overridden RenderStaticPreview can be used to render a list of assets converted into a single texture. This function will need user supplied source code that can merge the assets together. The size of the create texture can be supplied by the provided width and height.
If null is returned the builtin icon for the class type is used.
