Adding scale to Billboard Material (World Position Offset)

Hi,

I am working on a billboard material for Landscape Grass meshes.
While Foliage lets you assign random scale on meshes, Landscape Grass doesn’t – hence I’m trying to add random scaling inside the vertex shader.

In the attached image, both parts work individually, but I can’t figure out how to combine the World Position Offset instructions without distorting the billboard meshes.

Any help would be appreciated!

Many thanks in advance.

it may be a bit late but try an add node it should work
