Hello,
Please see the picture below, I’m trying to blend grass into rocks based on their normals in UE5.1.
There is no error with VertexNormalWs.
But, with PixelNormalWS, an error popped out with the message ‘[SM6] (Node PixelNormalWS) Invalid node PixelNormalWS used for Normal input.’
Does anybody know why? and how to solve it?
