Actionscript updating dynamic text
When the dynamic glyph cache is enabled, Scaleform 3 and higher version supports Blur, Drop Shadow, and Glow filter effects applied to text.Text filter support requires dynamic cache; when using glyph packer or static font textures filter effects are not supported.
Plus, an optional Blur filter can be applied to the text itself. If you add Drop Shadow and Glow filters to the list, only the last one will be taken into account. If the “shadow” or “glow” filters have “Knockout” or “Hide Object” flags, the text (the second layer) is not rendered.Combined with the dynamic adaptive glyph cache, filters work almost as fast as regular text.
