do receive transparent shadow work with the 2.64 build sun light?

I’ve been using the new 2.64 test build with harmony and I wanted to know if “receive transparent” works on alpha textures using the sun lamp buffered shadow. I clicked the “receive transparent” tab on the alpha material and it still shows up as a square plane where the shadow is displayed. I wanted to know if it can do this or it’s not possible.

Transparent shadows have never been supported in the BGE, I also don’t think they were introduced in the initial phase of the harmony project either.

I forgot spot lamps can’t cast transparency.
