Maya2011: Rendering Shadow-Channel of hidden object

Tried this for hours yesterday and it’s driving me crazy. the shadow channel always produces a black image with a pure 100%-alpha channel and no shadow anywhere.

I did "hide" a simple cube, put a spot-light somewhere and placed a flat primitive below as a floor.
The beauty channel is fine.


scene with object visible


scene with object: display / hide / hide selected object


shadow pass settings

any suggestions? 🙂

Thanks in advance

Editing PFTrack Geometry Imported to maya help

I have imported a tracked geometry from PFTrack to Maya. The issue is that when I click auto map it divides the uv up into to many triangle face. (I wish PFTrack would stop triangling up my models.).

Does some one know of a tutorial that explains this process or does any one have experience with this problem????

Filming projections

hello all,

I know this is more of a post-production kinda forum, but I thought someone here might be able to help anyway.

I was wondering if anyone could suggest how to get rid of flickering or strange waves of light or bars of colour that appear whenever I try filming projections.
We’re filming on a Canon 5D so its in progressive, and so far we’ve had the same problems whichever input we use on the digital projector. We’ve tried playing around with the shutter speed and with the refresh rate on the computer we’re playing the videos to be projected from but with limited success.
Can anyone help?!

Thanks,
Greg

Nuke 6.2v1 Roto tool question??

Is it possible to have multiple roto shapes visible in 6.2v1 while roto-ing with the ROTO tool??? In older versions of nuke, setting the bezier tool to color or some other tab would hide the points but keep the shape visible while roto-ing with another
bezier node. Am I missing something or did this option change in 6.2v1?? It seems like you can’t have more than one Roto node selected at a time.

Also, can I rescript the node to change this if I need to??

Cinesite destroys Los Angeles

Cinesite destroys Los AngelesLondon, UK, March 11, 2011 – Cinesite, one of the world’s leading film visual effects houses, has completed a series of stunning and technically challenging visual effects for the new epic disaster movie by Sony/Columbia, Battle: Los Angeles, which opens in cinemas today. Cinesite were responsible for many of the film’s standout battle sequences, including shots of smoldering downtown Los Angeles, the invasion of Santa Monica beach and an explosive battle against aliens.

Directed by Jonathan Liebesman, Battle: Los Angeles is a sci-fi thriller that follows a Marine sargeant (Aaron Eckhart) and his platoon as they take a stand for mankind against an unknown enemy thatÂ’s invading and destroying Los Angeles. Working closely with Liebesman and production vfx supervisor Everett Burrel, CinesiteÂ’s visual effects team was headed up by Ben Shepherd, visual effects supervisor, who spent 10 months working on the film, including six weeks on set in Baton Rouge, Louisiana.

CinesiteÂ’s Emmy award-winning work on the HBO miniseries, Generation Kill was a key factor in Liebesman choosing them for the job. Their expertise in creating detailed military hardware, helicopters, light armored vehicles and elaborate explosions meant that a pipeline was already in place which could be built upon.

To create the scenes of epic devastation, Cinesite applied realistic smoke, dust, fire and water explosions. Physical elements shot on location were composited onto digital matte paintings. Layers of haze, smoke and dust were created in Maya Fluids and CinesiteÂ’s proprietary software, csSmoke. The donut-shaped smoke rings seen at various stages are CinesiteÂ’s trademark in the film and symbolize the aliens landing. Liebesman set BenÂ’s team the task of creating dramatic but realistic smoke rings after the director was inspired by an explosion on set. The team rose to the challenge by experimenting with proprietary software and creating photorealistic thick black smoke rings which exceeded the directorÂ’s vision.

Cinesite also built the Commander Alien which was designed to have human mannerisms so the audience wouldnÂ’t at first identify the figure as an alien. The model was key frame animated and to make the Commander stand out from the other aliens, he was heavily textured and given a greasy, sweaty look and feel. The alien hovercraft was another element that the team generated. Based on original designs by Paul Gerrard, it features in the film as a gun platform for the aliens to fire from.

Additionally, the team produced the sequence where the Marines leave Camp Pendleton to tackle the invasion of Santa Monica airport. The plate was shot with three helicopters which Cinesite enhanced to a formation of 12 by adding CG ones. The airfield was further populated by tanks, light armored vehicles and armor, as well as atmospherics such as smoke streams and distant smoke rings.

“We really enjoyed working on this feature. It enabled us to use the full breadth of our talents from creature creation through to crafting complex elements. Jonathan was inspired to work with us after seeing our work on Generation Kill and trusted us to deliver something that would go beyond his vision. It’s everything you want from a disaster movie, and then some!” said Antony Hunt, Managing Director of Cinesite.

Where to get ORAD help

Hey guys, I’m not sure if this is the place for this, but I’m kind of desperate for some help.

I’ve been working with vfx programs for years and there’s always a lot of online community support and easy places to get help.

A couple of years back, part of my job became working with an ORAD virtual set system designing and maintaining virtual sets.

I am having a couple big problems with the authoring and playback programs for the ORAD (3Designer and Maestro) and desperately need some help, but oddly I can’t find any sort of online community discussing this setup.

For those of you that have worked with these systems, is there anywhere online that I can get help that doesn’t involve convincing the bean counters to pay large amounts of money for me to talk to someone in Israel?
