Project upgrade problem - The name 'm_CachedSmoothValue' does not exist in the current context

I upgraded one of my projects to 2020.1.17f1 (from 2020.1.16f1) and am seeing quite a few error messages. I’ve been keeping this project up to date throughout the 2020 releases and never had a problem before. One message that is repeated quite a lot is…

Library\PackageCache\com.unity.visualeffectgraph@8.3.1\Runtime\Utilities\PropertyBinding\Implementation\VFXInputButtonBinder.cs(36,17): error CS0103: The name ‘m_CachedSmoothValue’ does not exist in the current context

Any suggestions on how to remedy this?

I also have this issue with a new project made with 2020.1.17f. The issue occurs when adding and switching to the new input system.

you can work around it by going to Project Settings > Player > Active Input Handling and setting it to both.

other people have had the same issue.

Awesome! That did the trick. Thanks!
