In fact, I don't understand why Ocean eventually switched to a Blender. DAZ has excellent optional engine Octane, which gives a juicier and clearer picture, unlike the proprietary engine Cycles X of Blender. I'm not sure, but in my opinion...
Bro...
The Octane plugin is the biggest shitshow I've ever seen. I used it in 2020 and it's the worst. It's extremely buggy and OTOY has one developer on it to fix all the stuff. (After the last one quit.)
Check the OTOY forum and the Daz Plugin... Just take a look at what's going on there.
Their list of issues is growing longer and longer.
Octane itself is really good (Like for C4D/Standalone) but the plugin for Daz is absolute garbage.
Ocean will use the Blender as a render engine, and not engage in modeling and sculpting, so I can't find any reasons other than that Cycles are much faster than any engine I know.
Sculpting was the first big reason I wanted to move to Blender. Due to DAZ's (artificial) limitations, you can only sculpt in low-res there.
In Blender, I could work with high-res sculpting.
So please don't say it as if I had said I'd not engage in the extra features Blender provides. That's the whole reason to make this switch.
Bring everything to a new level. (Slow and steady without overwhelming myself.)
Let me give you a few reasons why I want to switch:
1. The ability to create my own environments/Pay freelancers for environments. (Seasons Winter, Autumn, etc.)
2. Animations/Cinematics. Entire 3D movies have been made in Blender. This is pretty much the biggest reason.
3. Sculpting
4. The entire physics engine. (Rain, snow, etc. that interacts with objects/people)
5. The ability to hire freelancers/Artists.
6. Growth. (Escaping the comfort zone from DAZ and investing in the future.)
There's just so much more about it than just wanting to render faster. (I think Daz renders faster tbh (With people present.))
Ocean uses Octane when rendering, so the picture is very different from the renders of other developers, even on the Iray engine. After all,
I render everything with Iray. (Except for one image.)
