you pretty much answered yourself – hair instances are always scaled so their Y bounding box fits the length of the hair it’s instanced on.
you can get around this by parenting the grass object under a (hidden) cylinder, and instancing that. The cylinder’s Y bounding box will define the scaling and you can freely scale the grass object underneath it.

I am trying to override this. I can't even figure out how to rearrange the stack so that the scaling of the object or points is done after the object is scaled to fit the guide hair. For instance... if I scale the grass blade (the instance object group) in Y then the grass field has short fat blades that go the entire height of the guide hair. If I put a deformation cage on the blade, it does deform, but is then stretched to fit on the guide hair in y.

I would like to animate the shape of the blade of grass, as well, using the shape animator. Am I maybe not seeing the scaling of the blade of grass because hair always tries to scale the y of the instance to match the guide hairs? Anyway to override that?

I am instancing blades of grass (in a group) to hair and any animated scaling of the instance does not translate to the hairs. Is there a secret that I am missing? I am following the docs, but some info must be missing. Anyone? -- Best Regards, Stephen P.
