I'm sorry you are running into issues. I just double checked, and I no longer have any references to ProceduralMaterial anywhere in the Visualizer Studio codebase. Please make sure that your asset has been fully updated. The easiest way to do that is to remove the asset and reimport it. Please let me know if this helps resolve your issue.

I just released a new update which properly supports Unity 2018. Sorry for the inconvenience!

Hey, I'm sorry you are experiencing issues with performance. With Visualizer Studio, the most expensive part of the code is the actual visualization that runs through the Unity framework, which allows customization on how detailed and expensive the procedure is. Have you tried adjusting the Window Size and/or Window Type on your Visualizer Manager object? Setting the Window Size to a lower value will increase performance at the cost of visualization resolution. The Window Type defines which formula to use when creating the raw visualization data. More info on that can be found here: https://docs.unity3d.com/ScriptReference/FFTWindow.html Basically, the higher up the list, the better performance, but lower quality visualization data. And last, you could try changing the audio channel to either Left or Right (if you didn't already), and it will only perform visualization on one channel instead of both, which will improve performance. Hopefully this helps get performance to where you need it to be. If you have any other questions or concerns, please feel free to contact me at AlteredRealityEnt@yahoo.com.
