I made this mod to capture some in-game footage without the distraction of whispers flying around in certain scenes. You can see it in action below in the trailer for Chapter 12 High Stakes Re-score



This mod affects all the regular hooded-figure type whispers throughout the entire game, including the fully modeled whispers in cutscenes and battles, the 2D hordes of whispers that fill up the background, and the circular barriers and domes. This also removes the most noticeable smoke and mist particle effects emitted by the whispers, but some of the smaller wind, sand, and distortion effects are not affected, and still visible.

I only made this to capture footage, but it's fine for gameplay as well. Whisper battles might be a bit harder since you won't see them at all, but you can still find them by attacking and letting the targeting system bring you to them. 

This mod does not affect the armed type of whispers that are introduced during the final battle of the game. This also does not currently affect any of the sound FX related to the whispers, so you'll still hear the wind soundscapes and attack sounds in battle. If there's interest, I can make another version with the whisper sound FX silenced as well.
