Can dforce hair be turned off for a scene?

Toobis

I suspect iray dforce hair is slowing down my scenes when I add one so is there any way to turn off a hair being dforce?

Not usefully - it isn't actively dForce, in the sense of being simulated, except during an actual simulation - it remains strand-based hair, though, so the geometry load is constant. You can reduce that by lowering the number of segments (if it isn't already 0) in the Parameters and of course you can make it invisible (make sure you are working on the hair, though, not a skullcap or the like).

When working on a scene and not doing anything with the hair, just click the eye icon in the scene panels next to the hair(s) to make it invisible until you are ready to run a simulation or render

any chance you could give me a screenshot on where abouts that is in the menu's? thanks.

I think Richard must mean the line tessellation value, if he is referring to the Parameters pane. I'm on my phone away from home, so I can't post a screenshot. Look in the store for a Line Zero shader product from Chevybabe25. It greatly reduces the system load of many dforce strand based hairs and renders beautifully.
