Thanks alot for your help! I agree, this should not be a secret setting…

For me, the problem did not show up before 3500 frames of rendering. So I will start to set the “Purge Every 1000 frames”… (it feels like this Purge thing otherwise could slow down rendering) I will do some test…

Thanks!

Did some tests, here are the results. Seems something is really eating up the RAM…

THANKS A LOT!

This is exactly what I was looking for. I installed the full Knoll Light package, then just added the unmult effect to the separate layers (the multiplied layers with ADD, Screen etc. ) Then changed to checkerboard background and you can see the actual alpha.

Then… render.. then… success!

Thanks, I have tried that but it does not work at all unfortionally…

Since some of the multiplied layers like GLOW creates glow outside of the Beauty-pass with alpha I cant use the Beauty as a mask because the glow will not show since it is masked away. I have also tried to do the Beauty white and lighten the glow, also to make the spec pass lighter and try to mask with the luma-matte, but that is not possible since it destroys the gradients and everything looks really bad.

So, I dont really know how to solve this… I think it should be possible since After Effect for sure creates some kind of alpha-channel information to make it work when there is a background.

I am also having this problem!!

I have lots of rendered tiff sequences separated into passes from Maya. It looks like this. First a Beauty pass with the main object and a real alpha channel, then on top of that a Glow pass, Spec pass, SSS pass etc. Those passes doesn’t come with a real alpha channel because they do not need a alpha since they are just black with lighter areas. And the lighter areas are all you want. SO, you use the multiply layer effect in the composition, the ADD (or Color dodge, screen etc). Voila! looks perfect against a background!

But it only works against a background, like a solid, a filmclipp or anything. BUT, if i want to export the Maya files with a alpha channel and not the background, its seems very hard. I tried to change to checkerboard background but I cant get rid of the Background. I really need to render just the 3D to make the workflow easier. (I have 186 layers in the comp right now…)

I have finally found a workaround to work with stereoscopic material in After Effects!

I am first finishing my left camera composition completely. Then, I copy the full project, rename it Ae-projects-RIGHT-camera-version then open it and replace all left-version-files with the right versions using the AE script “immigration”. Then I import the project in the left version.

This is a workaround and does make it very complicated if you want to continue to make changes in the left and right composition since you have to make every change twice…

so my conclusion is… USE ANOTHER SOFTWARE if you are going to make stereoscopic material.

[Jonathan Kempe]

I have looked around for a work around. A little more simple approch to stereoscopic 3D workflow in After Effects…

That is working with LEFT comp until its finished. Then just duplicate the comp and replace the footage. BUT, for now you have to replace every footage file one by one using “Ctrl+Alt+/ ”

Does someone know of a more advanced script that makes the replace footage command on multiple layers. That is, still you will have to manually put in some data in that script that replaces all “left” letters with “right”, or have some option to EXCLUDE certain text like “left” or “right”? And the filenames will off course be exactly the same without the text “left” or “right” and they will have to be manually selected.

Thanks

How does such a scriptline “replaceSource()” look like? Someone friendly out there that wants to help me start scripting?

This little script would be a great upgrade to really make After Effects a very good compositing program for stereoscopic 3D. Together with the new CS5 standard effect “3D Glasses” that makes you preview film or animated stereoscopic material (using the old red – cyan glasses on any standard screen) you could have a nice 3d pipeline for posting stereoscopic 3D for TV, Movies or Blu-ray…

Thanks alot Lennart!

I checked out the CSTools and they seem to be fine to start with! There´s one called Mocam and it seems very interesting.

If I like this way to work with cameras I probably go for the SteadyCAMPro sometime in the future.

Thanks!
Jonathan

Yes. Still its not a good way to do it. I want to have full control over the speed and point of views.

Watch this example movie and you see what I try to do.

How do you make this in Cinema with splines? Its impossible. Or? Any suggestions?
