IDOL!
THANK YOU VERY MUCH!
malaking tulong ka sa community natin! ikinararangal ka ng mga kababayan mo!

i do my zdepth in AE (after effects) mas madaling mag adjust kasi lalo indi ko na gagawin ulit ang procedure adjustments on parameter setting value nalang... anyway, maraming tutuwa sa tutorial mo, bro.. also play more on zdepth min and max value for better matte registration (white-to-gray-to-almost black mattes) hope it helps added tips thanks for posting...

astig ka unat!!! tnks sa pag add...

thank pare..gling nito

bro salamat sa d2 pero 1st tym ko makita itong zdepth kya khit me tuts diko pa rin ma gets medyo paki explain kung ano ang hlaga nito sa image?tnx bro in advance malaking help ito sa mga newbie d2.

sir sa pgkakaintindi ko at sa itsura nung final pic na nkapost, yan ang mgsisimulate ng depth of field ng real life camera lens.. kc out of focus ung mga elements n mas mlayo.. correct nyo lng po ako kung mali pgkakaintindi ko

Sir dickie....pede pa post ng tutorial mo about zdepth in AE......thanks......God Bless

no problem aayusin ko lang bro...

Nice one pakunat. Allow me to add a few things to your cool tut, here's one tip:

Zdepths are aliased by default. There is nothing you can do about it because every pixel is rendered based on its distance from the camera. These are the jaggies you see along the edges of the objects. This is a not good if you intend to add post process dof or fog because the jaggies too will appear the same. To bypass this limitation - use environment fog instead. Environment fog is anti-aliased.

HOW TO MAKE ZDEPTH PASS FROM FOG:

Set your environment far and near areas from the camera. Basically this is the same as the far and near setting of the zdepth. Setup your scene in such a way that you'd have white fog against black self-illuminated objects (use global mat override) and white environment color.

For AF peeps out there, the workflow for AF is pretty much the same as how you'd do it in PS. For DOF, add an adjustment layer above the image. Add a blur (I prefer lens blur) to the Adjustment Layer. Anything below this layer will be affected by the blur. To selectively add the blur - add the zdepth pass above the adjustment layer and use this as a TrkMat.

This process is a lot easier if you use CS3 AF - lensblur can use a mask layer (the zdepth pass) from within its controls.

i came across with this beautiful tut of sir pakunat's while i was browsing latest post. and i saw sir vertex u wer the one who posted last, curious bout what you have to say so i opened it.

i actually am having a problem with the jaggedness the zdepth produce and when i post process it in PS, lumalabas nga po ung jaggedness.. good thing i read this one again... and parang mas maganda effect nung environment fog for the DOF's alpha. i tried to make a test render and wala ngang jaggedness.

but then again thanks to sir pakunats tuts... this is really great.

sir vamp lestat patingin naman po ng sample nung fog and paano i set up TIA

ito po ung practice ko sir wenz

original image...



zdepth pass



jaggedness that is visible...



output using sir pakunats ps work




ito namn po ung environment fog pass



output using again sir pakunats ps work




well, as u may see, wala masyadong difference... pero there are cases na na experience ko lumalabas talga ung jaggedness, lalo na at high reso... maliit kasi reso neto, kaya di maxado klaro. pasenxa na for that. the point is that it works for the alpha in making our DOF...

this is how i set up the environment fog pass... btw... really dunno if this is the correct one... sir vertex, pa correct nlng f something is wrong with this...

first... go to environment... simply press 8 for easy access...

make your environment white

add fog on effects as it is shown here



adjust the fog's parameters



then make a material... pure black.. then instance it to the global override...



hope this one helps... parang tuts na din pala toh...
kung meron malabo, ask lang po.

Citing the vamp's example above, this value means that at the near area - there will be 20 % of fog and at the far area, there will be full 100 % fog. Anything in betwen will be interpolated by the values

The far and near areas are determined as I mentioned by the same setting in the cameras.

To render fog, you don't really need lights or shadows or reflections. The global mat override is fine enough.

If you aren't using the glossy properties of vray rendering, MB, DOF etc, fog pass can also be rendered with the scanline renderer (which is faster IMO)

yup2x.. i tried setting my far and near parameters in the camera settings just now... and it works more accurate rather than setting it in the fog parameters... it means that the black and white is more clear and i supposed this should be a better alpha...

tnx sir vertex for this one..
