Yes, you have to enable the“Extract any UVW type attribute with arbitrary name as UV map attribute” in the Redshift ROP.

I wonder why this isn't enabled by default.

There hasn't been separate display and render flags in almost 20 years.

Don't use flags to set what is shown in the render. The force object list configures the renderable objects regardless of flags. This is the way to control and objects render/display visibility independently.

Hey thanks.

Well, there is a display toggle in the Geo SOP to hide an object only from the viewport. In fact there's 2 ways to do that.

Why it's not a HairGen SOP beats me, since you can easily workaround that by hacking the SOP. So I suppose it wouldn't be hard to add a simple toggle to the parameters.

But then, this is Houdini....
