Hey there!
I downloaded Environment Set from NatureManufacture.
Now I wanted to add my snow material on the leaves of the tree. Therefore I made the leaves material to a material function but the opacity mask seems to be ignored there. See the pictures below:
This is the original material:
This is the copy&pasted material function with no working opacity mask:
This are both materials blended, but it’s ugly with the not working opacity mask.:
So my question is: How do I fix this problem with the opacity mask in the material function or in the snow-blended material? I hope you can help me!
