I'm just having an issue in masking the normals after changing the operation of the merge to stencil still I'm not able to see the color wit grade can you help with that
You dont really need the uncompressed exrs. You wont see the difference if you use it just for matts. And it will save you a looot of time and disc space. 32bit maybe because you need the negative values, but uncompressed is not really necessary in this case.
Fair enough! I haven't tested compressed versus uncompressed, generally I just go uncompressed with utility passes, because sometimes you will get artifacts if you don't do so. Generated UV Maps are one example of this (If you leave Zip compression, you will get a rolling artifact if that map is moving and is pre-comped with compression).
However, 32 Bit is still probably ideal for this.
@@CompositingAcademy if you're talking smartvector maybe but I do 1 or 2 px blur usually on smartvector. These techniques are interesting because you usually don't have the time to do these kind of techniques on TV shows so I haven't seen a lot of this stuff.
Cool. but you dont't show controls shuffle node in relight backdrop....
Would I need to mask out any moving object before hitting the analyze button?
Yes that would be best. This technique works best on shots with a lot of parallax though, so the camera needs to have some motion to it moving around the scene
what is use in shuffle node in normal pass lighting check on no alpha but
You are wasting disk space. EXR has has two lossless compression formats ZIP and PIZ. I personally use PIZ with 32 bit float. PIZ compression is faster to write, but slower to read than Zip and PIZ compression works especially well for images with a lot of noise or film grain. ZIP (1) is the fastest compression to read and write by default since Nuke can directly unpack in and out of scanlines rather than wait for larger chunks of data to be unpacked before beginning to read them. Although uncompressed files will be read faster than ZIP (1) if space is a premium compression is recommended
Cool that’s good to know. Usually with Utilities I always just did uncompressed, I know with UV generated patterns that are projected for example you have to go from Zip to uncompressed - otherwise you will get a very subtle distortion through the STmap that is noticeable in motion. Probably good to save on disk for position or normals I guess.
The Aridan Herr node dosent give me an alpha and I really don't get why, I've done like you, I really don't get it. And also my postion pass dosent look like yours, for me its green top left corner, yellow top right corner and red bottom right corner. On the bottom left corner its black.
Hey there,
Make sure before the position pass node you have a solid alpha. You can do this by shuffling the alpha to a solid "1" in the Shuffle node. The Adrian Herr node seems to require a solid alpha on the picture to work.
Also, make sure you are selecting the correct channel in the node (position pass layer that we created).
I have the exact same problem and I followed it all correctly, even used the nodes from the script and still have a full white alpha instead of the section I am ctrl clicking, did you ever work this out? Thanks
@@OscarsEditing Same here. Found any solution yet?
@@orfeasantoulinakis9856 no mate, pretty annoying
@@OscarsEditing Hey guys,
Make sure you are selecting the right channel in the node. If the position pass is in your RGB layer, then use that layer. Also, like mentioned above, make sure the alpha channel is a solid "1" (or pure white) before plugging in the node. It's a custom node from Nukepedia, seems to have a weird quirk that you need the alpha before plugging it in.
