Absolutely a good version.
Unfortunately I have hurt my hand, so I haven’t been able to do the tests I wanted. (I am writing this with the wrong hand)
I have made a very fast test and gotten some unexpected results.
I wrote earlier that YafaRay outperformed Sunflow on the speed.
I no longer think that is right. I have tried the SPR(v1.9) on some older projects that are quite big and complicated, and I found that Sunflow is A LOT faster. Especially glass, mirrors and glowing surfaces seems to slow YafaRay down.
On SH3D-demo projects, YafaRay is absolutely faster, but as soon as things start to demand more of the renderer, Sunflow can be more than ten times faster. ( 6 hours compared to 29 minutes)
Have a look at this ( small) project file: Boxes.sh3d ( 49 kb).
This is basically a very simple project, containing four boxes, placed 50 cm above a mirror, everything resting upon a white backdrop ( illum 0 ).
Boxes from left to right : 1 coloured white, 2 textured with a white texture , 3 same white texture applied to each side, 4 red texture applied to each side.
The renderings:
Default YafaRay = 1 min 30 seconds ( manually timed)
SPR(v1.9) YafaRay = 2 mins 48 seconds ( plus some strange texture effects)

Spr(vi.9) Sunflow = 5 seconds (!)

I will do some more tests when my hand is working again :)
