This website won't be updated anymore, here's my current one:
SVG To PNG Auto Import
Automatically convert your SVG files to PNG!
You don't have to export to bitmap yourself anymore!
Just place the script inside your project and whenever you place/update a SVG file inside your Assets folder, a PNG file is created/updated alongside it.
The easiest solution on the Asset Store!
The plugin comes with a pdf file with documentation and a FAQ section.
Works with both Unity & Unity Pro!
