By default, the plugin is always compiled with optimizations enabled. If you'd like to debug the plugin, you need to do the following:

• Make sure the plugin is in your project (not engine), and that you're in DebugGame
• Create an empty text file named VoxelDevWorkflow.txt in YourProject/Plugins.
• Rebuild the plugin. This will also disable Unity build for the plugin, so you should see >600 actions.
• You can check VOXEL_DEBUG is enabled in the engine startup log: VOXEL_DEBUG=1 will be printed
• The code handling this logic is here: https://github.com/VoxelPlugin/VoxelPlugin/blob/dev/Source/VoxelCore/VoxelCore.Build.cs#L31
