I have tried to find an information about that but unfortunately I have been able to find nothing so far…
Will there be any release for native 64 bit operating system ? Like MudBox?
So far the information known is, Zbrush is very likely not 64bit native , but 64 bit compatible (which just means , it’ll run fine on a 64bit machine).
The only thing that will fully use all your ram above 4GB, is Decimation Master. Which I kind of like, wished Transpose master was aswell, since I usually run into mem crashes with that too.
Dec master is 64 bit.
