[ HOU-2490 ] Vray hair Embree on/off inconsistencies.

[Dubbie99]

We are seeing inconsistencies when rendering V-Ray hair objects depending on whether Embree is on or off and with smoothing on and off.
Each of the permutations renders very different. I would expect them to all look pretty much the same besides the curve smoothness.
Embree on with no smoothing is particularly bad, with nasty artifacts.

Embree OFF


Embree ON


Embree OFF with smoothcurves


Embree ON with smoothcurves
