Alpha of Vector not displaying ?

Unity Engine
1

Hello everyone,
I’m currently try to use Polybrushes VertexAlpha for detail meshes of terrain ( wind sway ).
So I made a normal plane, painted everything red, and painted with a green color and 100% alpha the top part.
I selected the Polybrush/Standard Vertex Color as the materialshader, but unfortunatly the green is still 100% visible …

Does polybrush alpha not work , or did I something wrong ?
The expected result should be that the green is transparent , so half of the plane should be invisible …

Kind regards,
Daniel

Hi, I am having the exact same problem. Trying to create a plane that is part vertex-color painted, part transparent. How do I do this with Polybrush?
