Hey All,

For a couple weeks now I've been baffled by Daz3Ds "Catmark" subdivision algorithm. Does octane offer the same algorithm?

From my tests with octane in maya, and using maya's own subdivision algorithms, there is nothing similar. Octane's subdivision in maya looks the same as daz's catmull-clark legacy.

The real issue is that Daz's HD features only work with catmark not catmull-clark legacy.

Can anyone shed some light on how octane deals with this in daz3d and also if anyone happens to have maya skills i'm trying to get those catmark subdivision in maya so i can use HD morphs etc from daz.

Thanks!

I'm sorry, but I don't know the answer to your question (and I doubt anyone else will).

Subdivision has nothing to do with Octane it is done on the geometry before it is sent to Octane. So whichever one you set in DAZ its then sent to Octane and looks exactly the same. I've played with this and HD morphs to some extent and it worked without a problem. The only minor issue was that when you change the subdivision in DAZ the Octane plugin doesn't know about it so you need to explicitly rebuild your scene for the geometry to change.
