First I would like to say H16 is a really cool release and as an Indie user
could not be happier with my purchase..

Upon trying new hair/fur tools, pretty damn impressive I have to say
although the help file contradicts (unless I misunderstand) what actually works and
what doesn't, or is it a bug?

In the help it clearly states.

“Once you're finished styling the fur you can turn off the display flag on the Guide Groom object. The Hair Generate object takes the guide curves and generates hair from them.”

It says exactly the same thing in the video tutorial too. so whats the deal here how do you turn off visibility on the guide curves in viewport and still be able to render the fur?

When rendering it comes up with error:

mantra: Unable to resolve geometry opobj/torus1_groom/OUT_GROOM.
Please ensure the object is included for rendering.
You can turn off vm_renderable if needed.

Confused, can someone shed some light on this please.

I cannot see another way to hide the guide curves in the viewport when finished with them.

Thanks for looking.
