how do you change the outline so it doesn't change with object scale?

[laurentopia]

I tried this but that doesn't work

return 10*normalize(input.positionOS + outlineNormalOSUnitVector) * _OutlineWidth; //you can replace it to your own method! Here we will use the most simple method for tutorial reason, it is not the best method!

first you convert positonOS to positionWS
and convert normalOS to normalWS,
then use positionWS + normalize(normalWS) * _OutlineWidth

I have updated the shader to use world space outline width
