1.how can i add alphamap in pbr Material （like blender alpha）？

2.I download a material, It contains AO、Metalness、Roughness etc，I set AO image to AmbientOcculsionMap，one of Metalness or Roughness image set to RoughnessMetallicMap？
I See ： If provides RMA map in one texture, set both "RoughnessMetallicMap" and "AmbientOcculsionMap" to the same texture

I saw alpha channel is already in your first image with green leaves, why not just use that one instead of creating another image for alpha map?
