The alpha and luma options do not show up in the track matte drop down in After Effects

Hi!

The alpha and luma options do not show up in the track matte drop down in After Effects.

Track matte is where it use to be in After Effects, but the options for alpha and luma are gone.

What can I do to get them back? 

This is what the track matte dropdown looks like now:

Gracias yo igual estaba batallando para encontrar las opciones de Alpha Matte, alpha matte invertido, Luma Matte y luma Matte invertido y con este artículo me quedo todo claro, mil gracias.

Puede ser complicado de inicio porque estabamos muy acostumbrados a la vieja interfaz pero este artículo explica bien el nuevo cambio y queda todo claro una vez que uno mismo lo explora en el programa.

If it helps, turns out there's an invisible checkbox for inverting alpha masks (check Screenshot 1). And it seems that alpha and luma have been moved to the Mode column (Screenshot 2).

Why Adobe keeps complicating things?

Why Adobe keeps complicating things?

Because there's a million users out there that kept whining about the old system being too complicated for whatever reasons...

I'm not sure if you still need this, but if you do: When you view your layers, right after the four icons, there will be three empty boxes. If you hover over the middle box, a half-filled and half-empty circle will appear. Select the middle box to turn on Alpha Matte, and click again to turn it off. I've provided a screenshot for a visual.
