Vertical Snow Fade

I’m trying to create a landscape blend with snow on a mountain side. I now want to do a vertical blend to 0 on that mask.

Here is my scene and mat:


I tried putting the Linear Gradient node into the alpha, I’m not quite sure how to use it. The Clamped value seems like it might be my answer too, but again, there is no specific documentation I could find for the World Aligned Blend.

Any ideas? I’m sure there are a dozen ways to do it.

check your PM
basically you have to multiply your SnowBlendBias with the WorldPosition’s blue channel (Z), maybe add some value, and multiply with some other value (0.000x or so, small one)
