Developement right now is for the MAC but it has been promised that there will be a Version for the PC,Providing VECTOR gets off their DEAD arse's and just SELLS it to Scotts company,They want to Turn Bryce6 into a Higer end Software that will eventually rival Max or maya Or Lightwave...The first thing they have said they will change is the Rendering Engine...Granted that is still a few years off after Bryce6 comes out but it can be done...Like I said if only Vector would sell...
