alpha sorting issues

Hi - I’ve two objects (Unity 5.5)
one has a standard shader (opaque - ie land) and the other a 'Particles/Alpha Blended texture) (ie water)
They work just fine - BUT, when if I change the standard shader from opaque to transparent then it no longer cuts out the water - ie the ‘sorting/blending’ no longer works correctly.
Any help/suggestions to if this can be fixed?
Cheers

That sounds entirely normal - transparent objects typically don’t write to the depth buffer so they don’t “cut out” anything. If that’s not what you want, you might want to include a screenshot to explain your problem.
