adding shadow to green screen footage issue??
Hi Community
I am working on a 3d enviornment and trying to cast shadow from keyed image onto back wall. Added light and changed material options etc.
When i am looking at 2 views, On the left view which is custom view 1 the shadow shows up perfectly. On the right view which is my active camera the shadow doesn’t show up at all.
What am I doing wrong??? Obviously, i need that shadow on the active camera.
Sincerely

Are you using OpenGl?

Yes It is on.. Should it not be on??
And why is it showing up on one side and not the other??

Just turned it off… didn’t do anything.

OpenGl should be off – Adobe recommends that as well.
Do a collect and post the project for us to take a look and see if we figure it out.Tudor “Ted” Jelescu

Hi again Ted
I can do that and collect, however its 355 MB. A little high to upload. So when I toggle cast shadows on the keyed image, it works fine on the Custom View view. However, on the active camera view it does nothing. In addition, I am casting a shadow on a Boris continuum 3d text and it works totally fine.(in the active camera view) I am completely stumped.
If i delete the solid layer (continuum 3d text) the shadow casting in the active camera of the keyed image still won’t work.
I am keying the image with Primatte Keyer.
Anybody??

Do you have the keyed footage precomped and that precomp as a 3d layer?

Yup
Sean
you see, i could understand it not working at all and having a
mistake somewhere, but why it would work in Custom View and not
Active Camera is baffling to me. -
Duplicate your project, replace the footage with stills and see if the problem remains. If so, you can do a collect and post that project up.

So I rendered frame out to photoshop file. imported
in and made it a 3D layer. It worked as it should.Now what??
I am going to render out as an animation codec with alpha to experiment.
I can’t imagine this being a codec issue!the original footage is h.264 file out of a canon5d.
any other guesses as to what is happening?

Boys I am going mental here!!!
I am using CS5.5. Just tried the same thing with .mov with animation
with alpha. Exact same issue. Moving light did nothing to the keyed
image. It did move the shadow on the solid layer that is using continuum.As before, the custom view is correct, the active camera is not showing
shadow from the keyed video image.I am calling Adobe for all the good it will probably do.
aaarrgghh!!!
I am running a 2011 mac book pro with 16Gb of Ram.
Am I missing a setting somewhere about the active camera??
