Alternative to Mobile/Particles/Additive shader

Hi
im working with an animator that uses Mobile/Particles/Additive on Images in order to create a glow effect on UI Images.
that’s works as intended, except im having a lot of “no _Stencil property has found” warnings.
is there any straightforward shader alternative to achieve the same glow effect?

Is there an actual problem, or does the problem start and end with the warning? I’m guessing the UI stuff uses Stencils for masks so there can be situations where the glow particles don’t get masked properties.

You can download the mobile particles additive source code and add the stencil stuff.
