Hair particle object with array modifier - array doesn't show in render mode

Hello,

I’m making a brush.

I made a simple clump of hair (for the brush) using cycles 2.66 (clump shows up ok).

But when I tried to apply an array modifier, the array shows in “solid” mode, but doesn’t in “render” mode (only original clump).

I already tried "convert"ing the clump to a mesh, but same results.

Any ideas?

(Sorry if you see a second post of this, but it seems 1st post didn’t take)

Thanks Tradersam
