[VNgen] Workaround: Alpha blending errors on character attachments
Lucas C
DeveloperVNgen uses an advanced compositing system for animating characters with multiple layers, each of which can be individually animated. But sometimes, you may notice unwanted outlines around character layers. This is due to alpha blending errors caused by antialiased edges around sprites. Unfortunately, these errors are inherent to GameMaker Studio itself and cannot be fixed by VNgen at present. However, a few workarounds are available to reduce or eliminate the effect beyond visibility.
