I am happy to announce that Curvy now supports the huge memory advantages of upgrading to 64bit.
32bit systems only allow for 4Gb of memory - which can get quickly eaten up by a sculpting app with millions of polies. 64bit lets the app use as much memory as it likes - perfect for complex 3D scenes.
If you got Curvy on Steam you will automatically get the 64 bit update. If you bought it here please contact me with your original purchase email and I will send you a new download link for the 64 bit version.
