Alpha test in dx11?

[ggml]

how can a png with alpha show in a standard depth buffer dx11 renderer ?
tried ConstantAlphaTest but didn’t work as expected

Simplest way, in pixel shader specify before output:
if (col.a < threshold) discard();

(Not sure if it’s with or without())
That would break Antialiasing… tho

Forgot to mention there is also AlphaToCoverage on Blend Advanced

And more cool MSAA https://medium.com/@bgolus/anti-aliased-alpha-test-the-esoteric-alpha-to-coverage-8b177335ae4f

@ggml: Enable Blend State >> AlphaToCoverage (DX11.RenderState). This also preserves MSAA. But it works only if you have no depth tests like depth prepass applied…
