I am planning on buying zbrush from a 3rd party, one of the sites that’s a recommended vender to be exact. I just wanted to make sure I would be able to upgrade to zbrush 4 when it comes out for free.
Yes. ZBrush 4 will be a free upgrade for all license holders, regardless of whether you purchased from our website or from one of the authorized resellers listed at http://www.pixologic.com/resellers.
Happy ZBrushing.
