Ok, guys i did a test. Here same v3 renedered twice. One with Ray tracing on and Autosettings set on FINAL. the other just my way of rendering( NO RAY TRACING..render autosettings 2 lines to right of draft word) Ray tracing one took 8 minutes Non ray traced one took 1 minute ( around). And i don't see much of a difference, except for darker shading on the RAY TRACEd one. and well alittle better skin texture on the ray trace one too. By theway, P6 , i didn't use skin shader this time by the way. it's just v3 with her high res daz texture. 1st the non ray traced which is at Render settings: 2nd line to right of word "draft" on the auto render settings screen
