Hi Conrd,
I’m at about 18 min with quality 4/5. It depends on the about of gloss involved , if you are too reduce times.
In previous post 8 should have been 18.
One thing to note is you can move from calculating GI to Generate Faces when it says Render Complete . I used to wait for up to 8-10 min watching the program make multiple passes after GI , each time the image quality gets better. Then click Step #2 Generate Faces.
It seems you do not get any clearer ‘Face Generation’ by waiting.

I always add a floor / surface and then water image to create water. Haven’t spent much time on getting it better.
