Well spotted Rob - I can confirm that this info is correct: Hexagon 2.5.1.79 is available for free dload under your 'Product Library' tab once you have logged in to the Daz site. Assuming, of course, that you have an account! Which I'm sure you all do 😀
Daz are also continuing development on this, as noted by @undesignated in the general forum and further information can be found in the Hexagon Beta product page https://www.daz3d.com/hexagon-beta and the Daz forum discussion thread https://www.daz3d.com/forums/discussion/215001/hexagon-beta-version-2-5-2-109/p1.
Also, are we not allowed to hotlink to outside sites? Because I can't post with an external links and it's starting to annoy me.
