3D Materials

Overrides

You can override the Material used for the 3D Texture Preview. This is done by inheriting from N3DTexturePreview.I3DMaterialOverride.

An example is provided at NTexturePreview/Examples/Custom 3D/Editor/N3DTexturePreviewExample.cs. The file specifically operates on Texture3D assets named "3DTexturePreviewExample", but a method of your own might perform any logic to provide a custom preview material.

Installation

Ensure your project is on .NET 4.x by navigating to Edit>Project Settings>Player>Configuration>Scripting Runtime Version and switching to .NET 4.x Equivalent.

Edit your manifest.json file to contain:
"com.vertx.ntexturepreview": "https://github.com/vertxxyz/NTexturePreview.git",

Or pull the project locally and use the Package Manager (Window>Package Manager), adding the package.json file present in the root of the folder with the + button.
