"Lele's VRay Tools" Script Pack:Realtime Sky Added

[^Lele^]

Err, this was some blunder alright :P

The DoF preview is NOT linked to the actual physcam parameters.
For now, use it only as a visual cue to where your focus center will be, knowing that the physcam may or may not defocus in the same way (most likely not)

A form of correct (or near correct) preview is under study, but it ain't very easy.

Sorry for this

The script pack is now also available @ highend3d.
No changes to what's on scriptspot, just a newer place to find them.

Just been trying your script's Lele. V cool.

I wondered if you could give us a quick run down on how best to use the LC/PPT calc.

I dont quite understand what I need to do to get the best settings!

Thanks

[^Lele^]

There's no "best Settings".
It's merely another way to express the humber of subdivs and the size of the samples for the LC/PPT.
Consider an image of 1000x1000 pixels (1 MPx).
Setting the subdivs to 1000 will create 1 million samples.
Or a shading rate of 1 (1 MSamples/1Mpx).
The same goes for the sample size.
In the normal render dialog it's expresses as normalised fraction of the image size.
Ie.: a 0.02 in the case above would equal to 20 pixels (1000 x 0.02).
The calculator does just that: makes for you those calculations, so that you can set a sample size, a shading rate, and changing Image size will allow you to preserve them (change render size, the values set before will lead to different absolute sample sizes and different shading rates, reset them in the calc and you're safe to go).

Feel free to ask for more infos, should this not be clear enough.

[m_hinks]

umm, I think i understand, Ill play and come back with questions!!

I can understand the logic of sample size in pixels, but what is the shading rate refering to?

[^Lele^]

Imagine the LC as a paintbrush.
And your image as a canvas.
You're painting an impressionist piece, made of dots.
Now: how big will be the dots is your sample size.
Just how many layers of paint you'll lay on the canvas is the Shading rate.

[m_hinks]

thats does help, although being reminded of school is harrowing!

Just for example, your 1000 x 1000 image, what would you give as good setting?

Im presuming the smaller the samples the more you will need? or blur with the interp. samples dial

[^Lele^]

Well, smaller samples should be able to resolve with more precision corners and finer details and potentially lead to more noise if the sample rate is low, and/or the interpolation distance/number is small.

For an exterior, normally a shading rate of 1 doesnt' change much in terms of quality compared to a SR of , say, 5, due to most of the light shooting back towards the nothingness.
Bigger samples can also generally be used.

For interiors, things change quite a bit, as the chief property of the LC is it's "bounciness".
So raising the shading rate to 5 or 10 (ie. LINEARLY 5 or ten times more samples than there are pixels, or 5 to 10 coats of "paint"), in conjunction with a sample size of, say 3 to 5 pixels, will lead to very accurate results.
You may, from case to case, want to blur the LC a bit more (i generally prefilter it to 25 samples), to avoid mid-frequency GI noise, and to give the primary engine an easier time.

It's just a rule of thumb, feel free to test and report back different experiences, in case.

Updated the script pack for VRay SP2.
The Stuff Collector will now collect vrayIES files along with standard IES.
I made sure the VRay Light Monkey works with the textured area lights.
Get it from scriptspot as per usual (first post, my signature).

Hey,

thank's Lele

i try now.

[Fekta.studio]

I have some problems trying to install the script pack from main istaller in 3dsmax 2008 64bit - vray sp2. its give me this error.

[^Lele^]

Very odd.
The file, i can confirm it, is existent in the package, and entirely meaningful.
Did you try unpacking in a temp folder, say, in the root of one of your drives?
It looks like read access rights denial (my documents, desktop, some other folder here and there...).

im admin, and have all the rights, but its my bad, i drop it, not run it...

[cecofuli]

I Lele,

i found that Light Monkey v0.3 not change the subdivs for VRayIES. Can you fix it? Thank's

cecofuli

[^Lele^]

No.
The way the lightmonkey is set up is to mimic the standard vraylight interface.
I would need to create a separate iesLightMonkey for the scope.
Will look into it soon enough, for sure.
Thanks for the tip, Francesco!
