vraylog.txt decoder needed :)

Is it possible to optimize render times with this info in the end of vraylog.txt file

Number of raycasts: 19082406940
Camera rays: 359592456
Shadow rays: 2841686950
GI rays: 2011085449
Reflection rays: 444182631
Refraction rays: 124707525
Unshaded rays: 14938364864

For sure, and I have done that a number of times when I had to look at user scenes. For example, in this case, you get more unshaded rays than anything else. Unshaded rays are produced typically by VRayDirt and AO. Which means that if you drop those effects from the scene, you can probably get quite a bit of speedup. Next are shadow rays, which means that if you find a way to reduce the number of lights, it will also help. It also tells you that there is no point to spend time trying to optimize reflections or refractions as they take just a small part of all rays.

Best regards,
Vlado

Very interesting. Thanks for this advice !
I will take care next time I need to deal with my render time vs quality...

Great info!
Thanks Vlado!
