Is it possible to write an expression that adjusts a mix value based off of transform

Hey guys,

So I have a glowing object that scrolls from left to right. During that, I have an interactive light layer turn on and off as the object passes. So for instance:

x = 0
mix = 0

x = 100
mix = 1

x = 200
mix = 0

I will be animating the transform, but I don’t want to animate the mix. Is it possible to create an expression for the mix value that animates as the transform.x animates?

I have an idea:

In mix value:
Transform1.translate.x/100

This works for turning on the layer, but how do I work in turning it off at 200?

Thanks,
Andrew

integrating new 2d objects to final stereo shots

hey guys,

converting a complete 2d shot to 3d shot in nuke works very well for me, but i’m really a little bit confused about this:

i already got stereo footage (shot in stereo), but now i have to add in this stereo scene for example a airplane which should be integrated in the final stereo shot.

so i am setting up as usual my stereo views and now i got a read node for the left image sequence and one for the right image sequence.

would this the right approach?
– join the views
– project them on a card
– create a complete new zdepth
– displace them to add my new 3d object into it
– set up a new stereo rig to match both and reshoot it in nuke

i would like to avoid splitting my final stereo shot and shot again with a new stereo rig only to place my object in this scene.

how do you solve this? with stereo 3d tracking? or any better workarounds? :confused:

thank you guys

Timecode in Text node

Hi there,

any way to add a value to a Textnode which displays the frame number/timecode in Shake.
So far I’m using %F to display the number but I would like to add a custom offset to it.

Any pointers welcome.

Unexpected – “Batelco Infinity”

BATELCO "Infinity" takes you on a journey through people´s minds in a visual effects-loaded interactive film which has been causing a stir on Facebook.

At over three minutes long, the film shows several protagonists as they re-imagine the world around them, which marks the global expansion of Batelco, a leading Middle East telecom provider. Bahrain-based agency FP7/BAH teamed up with Spyfilms, Canada and City Films, Beirut, German directing duo Alex & Steffen and the german posthouse Unexpected to create this film along Batelco´s proposition of ‘Bringing ideas to life’.

After its launch on Facebook with an interactive webcam layer it soon got more than 118.000 fans and even more views – over 2000 daily new ‘likes’, an average of 83,000 daily post views, over 1 million wall impressions up to date and fans from 43 countries across the globe.

Besides one single take where the RED camera was used (the shot with the opening elevator door and the skater) the whole film was shot by New York-based DoP Simon Coull on four Canons 7D, two 5Ds and the coolest gear like Eric Austin´s small camera helicopter from www.helivideo.com.

German-based studio Unexpected Postproduction produced over 100 visual effect shots for the film, ranging from small enhancements, sky replacements, digital animals and stunt-doubles to a subway transforming into a huge rollercoaster rushing inbetween high rise buildings, F1 racers chasing each other on city streets and futuristic gliders blasting through the city canyons. A large number of those shots are 100% CG as they would have been almost impossible to get in real life!

Relight Node in NuKe???

hi,
just want to know what is the purpose of relight node?? can anyone suggest any tutorials or links???:confused:

>> Gizmo better than Groups ?

Hi,

Why every body wants to work with Gizmo, and not with Groups, what’s so nice in it ?

Thanks, I’m really curious about that.

Error message: layer mask: mask.alpha already at index 1 instead of 0

Does anyone know what this means:

layer mask: mask.alpha already at index 1 instead of 0

It started popping up when I used a Copy node to copy an alpha from the A input to the mask.a of the output (B input has rgba). I did this because I wanted to render out one set rgb and two alpha’s to exr.

Everything works just fine (including network renders), but the error message confuses me.

Thanks!
