V-Ray 6 for Cinema 4D Update 1 - reaction

[akos_kiss]

Hi All!

I've just looked at the release notes and updated to the new version. And i have to say i'm ecstatic! This update is amazing and has sooo much quality of life improvements!
I just wanted to say a huge Thank You for the new features and fixes that are included!

[viktor_angelov]

Thank you for your kind words!

Enjoy your time with V-Ray!

[haniel1107]

plus one! Thanks!

[Rickmc]

Great Work

[stefan_laub1]

+1 from me too!

Same here, great work guys!
- light decay - finally!
- Nvidia AI upscale - interesting - I was always wondering about similar to DLSS technique for rendering.

- New path guiding light method for Light Cache (experimental) - how does it work exactly?

[sirio76]

how does it work exactly?

Turn it on, and enjoy the speed up.
I’m testing it in many circumstances because the speed up is scene dependent, by increasing the LC subdivision to 3000 I rendered an interior scene almost twice as fast, but is not always like that.

Thanks, very interesting. If it will help with airplane cabin scenes, I would be delighted

You can check this blog post for more details on the implementation and how it works. You should just keep in mind that this feature is still a Work in Progress, so it will not affect all scenes. Also, while we gradually add more parts of the scene to use this feature, preserving render results of scenes using this option, will not be guaranteed in future versions (although differences should be minimal and negligible). This is why it is marked as Experimental.

Thank you - any downsides in rendering animations yet? More flicker, random noise?

Tested in one ariplane cabin scene - almost no result sadly, same noise - 2:38 vs 2:30.
With LC on 3000 it just bumped up one minute.

On such a short time increasing LC will never help because the time you gain (if any) will be wasted computing a longer LC solution. As said is scene/lighting dependent and will not have the same impact everywhere, in my interiors using physical sun I get quite often a noticeable speed up. Probably if you have a well lit cabin you won’t have dramatic improvements.

sirio76 Hey,

Just wanted to post another example - a topic on this could be interesting. The experimental LC in exterior not only renders same amount of time, but produces much more noise (wall) and more gi light on the vegetation (could be from more LC subdivs):

Expermental vs Normal:

[sirio76]

As far as I understand that settings should work better in interior or scene with many GI bounces, to be honest I've not yet tested on exterior because is not supposed to bring benefit there. Have you read the article by Vlado? It will help to understand where you can expect speedup
