Notes: I've added a branch that contains no helper code other than what comes with UE5 and set it to default. The no helper code is under the no-helper branch with the helper code being under the main branch.
//-----------------------------------------------------
The non default branch of this plugin has a dependency on another - UE5ShaderUtils You find it here: https://github.com/RyanSweeney987/UE5ShaderUtils
Git: In your plugin folder run the following: git clone https://github.com/RyanSweeney987/UE5ShaderUtils
Download: Open the repo, click on the green "<> code" button and click on the "Download ZIP" option. When downloaded, extract the contents into the plugin folder, ensuring the following hierarchy:
./Plugins/UE5ShaderUtils/.... With files such as UE5ShaderUtils.uplugin inside the UE5ShaderUtils folder
