Render Alpha Zbrush4

ZBrush Usage Questions
#1

Hi

I try to make a mask for Photoshop
I make a render with best quality and then I clic create maps.
Any option I choose (masks, Img, dep…)
I have this message :
This image have not been generated
Please execute a best Preview render and try again.

What do I do wrong?

I use zbrush4 on a Imac 2.8GHz Intel Core i7 with 8 G of ram

Thanks

Fred

Best Render is not the same as Best Preview Render. BPR is the square icon at the top left of the Render palette, next to the Create Maps switch. (It’s also on the top of the right Shelf next to the canvas.)

BPR requires that a model be in Edit mode. It only renders polygons; not pixols.
