Display normal map with alpha / masking

[KonataNX]

Hi,
I have 1 thing that I still don't know how to do even now~
For example, I want to create a leaf which built by plane at all~
I draw the diffuse map with alpha channel (opacity)~
Then create the normal map on it~
The thing is that the normal map won't display perfectly on the plane~
The diffuse alpha area still have normal information~
And if I turn on alpha test, the result still not good~
Even in Marmoset Engine or 3Point Shader~
The alpha edge is very weird and jagged~
How do I display a good quality normal on an alpha object?
Hope somebody know this, Thanks a lot~ =)

Post some screen shots and your texture flats so we can see what's happening.

What does having a normal map have to do with how your alpha looks~
You can try alpha to coverage in marmoset~

Yes~ Thank you EarthQuake~
I checked the alpha-to-coverage with 0 alpha threshold and it work fine~
The shadow below the alpha follow the alpha edge as well, cool~
Last time my problem occurred is because my alpha is not 100% white~ (Dirty color)
I checked it out and paint it fully white color inside so that it solved~ ^_^
