If set to [code]true[/code], glyphs of all sizes are rendered using single multichannel signed distance field generated from the dynamic font vector data.
If set to [code]true[/code], glyphs of all sizes are rendered using single multichannel signed distance field (MSDF) generated from the dynamic font vector data. Since this approach does not rely on rasterizing the font every time its size changes, this allows for resizing the font in real-time without any performance penalty. Text will also not look grainy for [Control]s that are scaled down (or for [Label3D]s viewed from a long distance). As a downside, font hinting is not available with MSDF. The lack of font hinting may result in less crisp and less readable fonts at small sizes.
[b]Note:[/b] If using font outlines, [member msdf_pixel_range] must be set to at least [i]twice[/i] the size of the largest font outline.
[b]Note:[/b] MSDF font rendering does not render glyphs with overlapping shapes correctly. Overlapping shapes are not valid per the OpenType standard, but are still commonly found in many font files, especially those converted by Google Fonts. To avoid issues with overlapping glyphs, consider downloading the font file directly from the type foundry instead of relying on Google Fonts.
