I'll have a look at them but up until now I have not used billboards yes. The premade ones never were what I needed.
I think I have it set at 15000 standard but I am quite sure these didn't get that far. They either timed out before that or finished rendering.
As both the Plug-In & Billboard Builder are very new, it's not that surprising to find people reluctant to use billboard's, as firefighters in a medieval scene look a little odd....but if a little thought & time making the right images to make into a small crowd, that's only 2 or 3mb for 6 figures, has got to be better than one figure of 50 or 60mb each, plus clothing....And a lot less stress on the hardware....
