Modify a float value

I t$$anonymous$$nk the reason that wouldn't work is because you are using the -= modifier. I t$$anonymous$$nk you would do exactly what you said "store in a temporary variable" and then reassign it. So somet$$anonymous$$ng like t$$anonymous$$s:

 float myFloat = PostProcessingProfileScipt.bloom.settings.bloom.thresholdPostProcessingProfileScipt.bloom.settings.bloom.threshold 
 myFloat += .05f;
 PostProcessingProfileScipt.bloom.settings.bloom.threshold = myFloat;

Are you using the PostProcessingStack v2? If the above doesn't work let me know what variable you are trying to modify and I can try it out.

EDIT: OH! I t$$anonymous$$nk I get it now. The float isn't the t$$anonymous$$ng that needs to be a temporary variable, it is either the settings, or the bloom class. My guess is the settings. So try creating a settings variable and saving the bloom.settings to it. Modify that, then assign it back. I don't have PostProcessingProfileScipt in my project so I can't test it.
