Minus_Alpha argument

Sorry, for the double post, but I forgot to mention that this only works with #PB_Shadow_TextureAdditive.
I don't believe it's possible to get the desired effect with Modulative or Additive shadow types.

Check my previous post. Should take care of his and your problem. I think.....

Thanks Samuel. I'll be experimenting with your example.

Yes. It's working. Thanks Samuel!

Hmm, look at my screenshot. The shadows don´t work correctly...

Yes. But it is a shadow. Then we can find the settings.

I'm guessing your talking about the shadows being on both sides of the tree trunk. I've had this happen before if my mesh is below the ground.
Try raising the tree to match the ground level and see if that fixes them.

EDIT
I believe this is an issue with TextureAdditive shadows and not the material script.
Hopefully, raising them will solve your problem. I'll try to find out why it does this later on.

I do not mean the treetrunk, but the foliage. Look at the leaves, they´re overlapping itself and destroy the shadows of the others...
