zdepth problem

Bakit po ganito 'to?
'Pag nagcre-create po ako ng bagong channel sa raw render ko, na natransfer ko na yung zdepth output image, eh all black lang ang lumalabas?? help po mga master.

ito po.

you will need to change the default values of your zdepth distance parameters.

see this one sir

and or this one, same procedure din

salamat sa pagdaan mga master.. ntry ko n yung ke sir pakunat, yun po yung method na sinunod ko pero ganoon yung output.. pero bago yung sa'yo sir RM. sigurado na gagana na yan. salamat po ng marami. GB

mapapansin mo, wala gaanong gradient ang zdepth mo, ibig sabihin, hindi sya makakapag produce ng magandang depth of field. Try to change the range sa camera mo.

mali kase procedure mo sa paglalagay ng alpha channel, review mo ulit iyong tutorial..

yung parameter ko po kase sir bok eh min: 50, max: 150

gawin mo 0-150. Dapat nasa buong range ng distance ng camera mo.

anong ibig sabihin nun sir?? eh paanu po yung sample ni sir pakunat na 1000-3000??

baka mm ang gamit nyang sukat. Meaning, nasa 1m-3m ang subject. Try mo mgtest render. very low lang saka maliit lang. Para makita mo ang difference ng range.

sige sir.. paanu po pala yun, may nakikita akong may unit sign yung mga number nila. paanu po palitan yun? nakaenglish yata po yung akin.

Your values would not mean anything to anyone not working on your scene because everything will be dependent on scene scale.

One technique to visualize where your zdepth starts and ends is to turn on
either viewport clipping if you'd like to see it in your camera viewports, or use what I do - I turn on the environment ranges in the camera properties.

By turning this on, you will see an editable range in the top view, the start range tells you where it starts and the end tells you the obvious.

I normally do not use a value of zero for the start because the grayscale starts from the camera and you will lose valuable tone definition in the resulting zdepth pass.

Also do not encompass the whole scene as this will result in loss of detail and confidence by your clients! (joke!)

One more tip is to use floating point file formats, by doing so - yo uare technically extending the grey values to more than 255. Thus allowing you to apply levels to post adjust where you'd want the focus.

I forgot to mention that you should copy these values to the zdepth pass parameters in the element part of rendering.
