How to make sprite mask only apply to only specific sprites

Hi All

Im trying to make a slider script, which creates 4 child game objects

SliderFull spriteRenderer
SliderEmpty spriteRenderer
SliderMask spriteMask
SliderPin spriteRenderer

Ive set the mask interaction for the SliderFull to Visible inside mask and
Ive set the mask interaction for the SliderEmpty to Visible Outside mask

Which works but there is no simple option to specify which spriteMask to use and I only want the SliderFull and the SliderEmpty sprites to use the mask, I intend to have several sliders and GameObjects in my project which will need their own "separate" spritemasks, so how do I ensure that this instance of SliderMask only Applies to this instance of SliderFull and SliderEmpty ?

Thanks

 

sorry to post on a dead thread but did you ever figure this out?
