Some first impressions

[möbius]

Hi Guy, Happy to be on board for the Lavina beta...

so i just installed it and gave it a test run on an quite resent interior szene. I must say it rendered the entire scene with just a few issues but so far it looks promising to me.





There are two questions i have ...

1. What is the longterm plan for Lavina? Will it remain a standalone tool, or will it evantually become a render plugin for a DCC application?
2. Are there plans to improve the realtime experience? I ask this, because from a pure user Standpoint for now it appears more like a fast progressive renderer with a densoiser. I would have assumed, that it would not recalculate the image when i move the Camera but rather just progressively bake the lighting into the scene in the Background and only recalculate when i change the Light or alter the szene.

Cheers Markus

If you don't mind sharing the scene, it will help us figure out which features to add support for.

No concrete plans yet, but it's certainly something we intend to explore more.

That's what happens for the secondary GI bounces and the light cache. However, for the primary GI bounce, we don't have a good solution yet.

Was that previously rendered with GPU in vray next?

i'd like to try lavina but we'd need to get a new card and will hold off if it only takes GPU scenes.

Hi Markus,

Project Lavina will first come to market as an independent application. That is what this Beta program is assessing.

>> I would have assumed, that it would not recalculate the image when i move the Camera....

As a pure ray tracer, any change to the scene requires the entire image to be recalculated.

>>...rather just,,, bake the lighting into the scene in the Background.

Unlike raster solutions, there is no baking in Lavina - your scene's lighting is always evaluated.
This means your FPS while editing, or animating, should be the same as it is for just navigating - and it also means what you see is always correct - that there is no "preparation" phase where things are not correct.

Kind regards,

I’m in the same position. I would like to try it but unfortunately bought and RTX 2060 a bit before the rtx 2060 super, which is listed as the minimum required, came out. So I also would need to by new graphics.... card after already having done so somewhat recently.

You can certainly try it on RTX 2060, it's just that the performance will probably be quite bad. However, this depends on the scene as well, for certain scenes it might be enough.

In fact, you can even try Lavina on one of the Pascal GPUs that nVidia enabled DXR on.
Such as 1070Ti, 1080Ti, but performance will be very bad.
Running Lavina on these GPUs is useful only for comparison to the RTX GPUs.

I run a 1080ti. Performance isn't amazing but it's fairly usable on an interior.
Showing this to our tech guy may have nudged him to upgrade our cards.

I didn't realise this would all go through vr scene export. Are there future plans to integrate this more into a traditional workflow (3dsmax)?

Many possibilities exist. Please suggest what would work best for you and why - we want your opinions!

As Vladimir mentioned, the 2060 will work - just more slowly. The RTX's CUDA core count, clock speed, and RT core count all impact Lavina's performance.
In the case of the 2060, it scores 75%, 85%, 75% (95% in boost) on those traits in comparison to the 2060 Super, so multiplying those together shows that you should expect about 1/2 the performance, or 60% if the boost clock is being used.
Those numbers aren't guaranteed, but it's a good measuring stick to use when comparing and choosing GPUs.

And that all said, your 2060 is still much better to have than a previous generation Pascal card that doesn't have any RT cores.

I bought the 2060 as a card to run the UI, with an idea to add a second card if/ when I decided to take a stab at the gpu rendering workflow.

Such as 1070Ti, 1080Ti, but performance will be very bad.

I exported a full scene of a car (CAD-data, 20mio polies, 3500 parts) into Lavina, and was quite impressed witht the speed on my single 1080Ti. It ran very fast!

Nice to hear And the good news is that it can go even faster.
