Retopology for scanned data

ZBrush Usage Questions
#1

Hello all,
Trying to retopologize a 3d scanned beetle, about 1.3 million polys. When I select topo from topology menu I get an operation cancelled notice because my mesh is larger than 15000 polys.

I have been off Zbrush for a while and am new to 4.0, perhaps I am missing something simple? Does my model really need to be less than 15000 polys? Since it is scanned data I do not have lwer subd levels. Would really like to generate a clean topology then give UV master plugin a try.

Any advice would be greatly appreciated.

Ok, if 15000 is the limit for retopo perhaps i can use decimation master to work backwards and recreate lower subdvs?

Is this a possible work around? Please help!

Thanks.
