Major Update v4.0

In this update v4.0, the shader has been heavily modified with a whole new javascript codebase, and now has a lot more functionality and usability, however, there are some drawbacks as well. Here are some key highlights of this update but internally it has been updated a lot, for a detailed changelog, please refer to the extension script itself.

Auto-grabbing of material types from the editor

Auto application to all the objects in the scene

option to exclude the object from being lit by the shader so that you can have internal lightmapped, or dynamic lit objects along with the custom shader lit objects

Removed unnecessary properties from the shader action and instead of based on light, making them into material-based properties

Added Flashlight with many properties and toggle to turn on and off the flashlight, so you can control the intensity and tightness, there is also a flashlight defects effect with controllable intensity

Vertex Colored object support

many major and minor bug fixes.

As this update uses a whole new codebase, new bugs, and other issues might pop up, please let me know of the bugs that you encounter.
Here are some drawbacks or known bugs for the shader:-

Normal maps might show artifacts on animated meshes if UV islands are used.

The game will go unresponsive until the shader gets applied to all the objects in the scene.

Framerate will get affected if the scene is complex, i.e. if there is a huge amount of materials and objects in your scenes.

I am still trying to find ways to optimize the shader as much as possible so that we can have a workaround for the drawbacks of material creation in Coppercube.

Please watch the usage video on YouTube to get to know how to use v4.0, it also comes with a demo though.
