I know you, guys, told me that you cannot do alpha shadow PER object. So if i want light to shine through a glass ALPHA SHADOW must be enabled globally.
Can you at least add a button in diffuse and glossy material "IGNORE ALPHA SHADOW and do not calculate" next to opacity map. It is very important.
One of the examples:
I have a car where I would love light to shine through the glass. But I cannot afford the render time because I have lots of trees with opacity map used for leaves on the background. So if i enable ALPHA SHADOW just to see a light shining though a car windshield then thousands of trees on the background will be calculating alpha shadows for the leaves and this slows down my system by 6-8 times and we do animations only.
And the trees shadows look great with alpha shadows off. So if you had this feature "ignore alpha shadows per material" I could've had light shine through car glass and disable alpha shadows for tree leaves making my rendering still very fast.
Could you send me the scene, so I can try if the implementation I have in mind actually makes a difference? I still don't think it does, but it's worth a try.
