For those going "WTF is Orange's alternative?", see here:
Hudell was awesome and made it so you should be able to just pull Kaus' plugin out and drop this one in place, with no changes to notetags and such.
For those just arriving...
The creator of this plugin (Kaus Ultimate Overlay) is permanently banned from this forum due to theft of graphical resources. This plugin will have no updates and no support. Please use Orange Overlay linked above.
Sorry for the delay. What I did was get the KSU_ParallaxSmoothing plugin and set it to ON
He's not going to respond. He got banned for life for stealing art assets. So I even if you can find it. I wouldn't take it on faith that he had permission to use it.
Dang, what a shame. (That it's stolen, not that he got banned)
