I'm trying to control visibility of Hair / Fur geometry and thus playback speed in the viewport.

But when I use Bundles to control the visibility, it seems to have no effect on playback speed whatsoever.

Looks like I have to actually hide the "Hair Generate" SOP with the Display toggle on every single "Hair_Generate" SOP, and then force it in the Render Output to stop Houdini from calculating the Hair while playing the anim in the viewport.

But that's just a horrible workflow when I then need to hide and unhide certain hair SOPs from the render or not.

According to the manual the only alternative to control the hair visibility seems with the RMB display toggle on every Hair Output separately, but that seems broken for hair, besides that its just a horrible workflow because one can't adjust multiple Hair Outputs at once. So try managing multiple Hair Generators that way.

Is there a more user friendly way to control Viewport visibility and Render visibility separately that also affects calculations / playback speed as well ?
Like layers in XSI, where there's a separate control for Viewport and Render visibility ?

Or should Bundle Visibility affect playback speed as well, and is this yet another bug ?

Its a Request For Enhancement

Yes, I'd like that option as well, among other things.

But unfortunately the Houdini GUI is a bit outdated, to put it mildly...

Did you send support an RFE ?
