you want to play with nuke? now you can for free!

tried with no switches and with different ones...but to no avail, error stays the same. i tried using rc2 and 3 and the matching converters...nukeversion is 4.5.21

damn, i cannot reproduce this problem.
i have been using the vrimg stuff for a long time too so i would know if this was messed up.

[instinct]

odd. need to look into it again then. does vrimg saving also solve the premultiplication problem ? or do you restrict to not use the raw passes?

I guess rendering to vrimg and then extracting the channels would be about the same as rendering to multiple EXR channels from vray frame buffer section, wouldn't it? Plus you avoid that extra step converting files...I understand vrimg is better when dealing with hires stills, due to the amout of ram u save, but i dont see the benefits rendering an animation...

[instinct]

the converted exr is ONE exr per frame with all the channels integrated.

Uhmm i didnt know nuke was aware of that. As a combustion user, im used to rpf, and this format can't contain layers, only integer channels. So ur telling me nuke will let u separate a reflection layer for ex, from a single exr file? Like a kind of super PSD?

[instinct]

yep. an exr can have up to 64 channels and nuke is aware of all of them. that makes a nukescript a LOT less cluttered. Exr has incredibly nice additional features. like each chan can have a different colour depth...different resolutions, there can be multiple resolutions of the same layer, it can be tilebased instead of scanline based...etc.etc.etc :P

I am going to test it right now. Thanks for the tip, Thorsten!

P.S this is my 500 POST! Yeehaah! :P

Anyone know roughly how much nuke costs?

[dlparisi]

~$5000 + $999 Maintenance if this is still accurate...

Cheers for that - After effects exr workflow doesnt seem the best so this might be an idea...

what's very important to note about how nuke deals with channel data is that it can group the channel data into layers.
why is this important?
well, other apps take channels as seperate data elements and leave it at that. if you have specular (red, green, blue) that's 3 channels.
you have to combine them and then do the merge operation.
this is sub optimal.
ideally the software knows its a triplet and can just deal with it.
nuke was designed with this theory in mind and vray's exr's adhere to it amazingly well. additionally, nuke supports the data window in exr which means that you can have a 1920x1080 image plane but the tiny jet, car, person, in that shot is only 300x300 pixels. nuke only processes those 300x300 pixels. as you can see, that results in a giant savings of rendertime

i have been playing with it all day and i must say it´s vastly different from combustion or AE. I can barely finish a composition and render it to disk..
The all-in-one exr is exciting but workflow is rather intimidating...
Despite the above, compositing with nuke is lots of fun and very promising.

should i do a very quick tutorial that gives a little teaser intro to nuke?

yeas please!

tut would be great.
