V-Ray Scene Optimisation Script

[kosso_olli]

Oh dear, nice to hear that you are alright. Shame about that car though, what was it?

Regards

Thanks lele. Only brute force will fix that engine now. It's always a disappointing surprise when real life intrudes into virtual serenity.

[^Lele^]

Hey, thanks for the wishes, both of you guys.
It was truly quite scary, and my girfriend was beside me, which made the (unscathed) aftermath all the harsher to bear, unable to not think through the what-ifs.
I'm sure a night's sleep will set me back on the right track, recovery from mental exhaustion is something i ought to be quite used to, by now... :P
Olli, it was a BAD italian car, a Lancia Lybra.
1.3 tons for 130 bhp.
With the oil pressure gone, steering the thing and applying the brakes required quite the steady effort.
Here's a picture of the dropped rod shaft, to give the most physics-minded people an idea of the forces at play.

With the oil pressure gone

That'll do it...

[^Lele^]

eh, the pressure went in a big white cloud, after the bottom of the engine exploded.
A stroke of huge luck that the wheels kept turning when i pressed the clutch, as the whole crankshaft is in bits.
Ah well, enough of this madness. :P

One more question about putting everything at its default: is this true also of the LC samples. Or should you use the Sqr(renderheight*renderwidth)? Is there a post where vlado states how to arrive at the numbers.

Sorry for the late reply; there is no need to change the light cache settings when changing the resolution.

Best regards,
Vlado

[rajdarge]

so how then do you:

set your AA as it's needed to clean dof/moblur/high frequency geo or texture detail, and the simply use the "min shading rate" spinner to sample multiple times per camera ray shot.[\quote]

DO you pick a sample of the image with region render and just twiddle till it looks right?
is there a post or something that sets it out. Also the "new universal settings" I looked for this in the forums (tricks and tips) and found pretty much the same universal settings since 1.5.
Sorry to go on about this topic, but I've a lot to catch up on.
@Lele: Vlado's approach has the advantage of working with IRmap does it not?

[^Lele^]

DO you pick a sample of the image with region render and just twiddle till it looks right?

You'll have to, picking not only the right parts in an image (ie. the hardest to resolve) but also across an animation (ie. the longest blur trail, and so on).
That's the theory, anyway.
I've seen it done right and wrong ina million different ways...

@Lele: Vlado's approach has the advantage of working with IRmap does it not?

The script too, if you left the GSM @ 1.0 and changed subdivs for indivisual effects, to achieve the same target SPP.
Edit: unfortunately, given i do not use IRMap, i didn't care to include it in the presets (nor will i, sorry.) and as a result the high GSM the script uses will make it render nigh forever.

[AlexP]

and as a result the high GSM the script uses will make it render nigh forever.

To counter this I just reduced the Hsph subdivs by eye to whatever gave a similar looking distribution (similar to what I had pre-script)
Completely non-scientific but worked well enough

[^Lele^]

eheh, nope, that IS very scientific.
GSM multiplied, and YOU divided

Oh dear, that one looks hideous! But nice interior I have to say, with leather upholstery at least. So what comes next? Do you have a passion for these italian cars? I think I can remember you driving around in a Fiat Uno back in the days at Macke...

Umh, no, never had that.
Maybe you think of the Tipo, another ugly monster.
The only car i ever chose, was nearly 20 years ago, now, an old and faithful Fiat Panda.
After that, with all my travelling around, i got assigned, at each return home, whatever my family decided they didn't want anymore.
And they kept scrapping the previous one i was driving.
So i had this coming, i guess, driving EoL vehicles all this time. ^^
Depending on what will happen in the next few days and weeks, i may choose to stay car-less, or buy another used Panda: that thing never stops, no matter what you do to it.
I seriously only enjoy driving on the track, and do the least possible amount of driving on the road.
If i was to leave Italy again to chase jobs, well, having a car would be quite useless.

Oh. Lele... glad you guys managed safely from your car trouble.

Thanks for more briefing on the script,
and I will stick to the usual formula of less camera rays and more secondary rays.
Thanks again.

[Neilg]

I've not had a car for 4 years now, it's been liberating. Got a massive amount of cycling in
Glad to hear you're ok.

I was indeed collecting only the file paths for the output part of the V-Ray settings.
Updated the struct file, so that it now ought to keep all of the panel info.
Script updated in the first post of the thread to v1.49.
