Why is this happening?
I have 15 or so planes lined up side by side with a png sequence of a sine wave animating outwards. I have set up the material properly using the color and alpha channels and with just a few of them side by side, everything works perfectly. When I line up all of them together, I am getting the accurate transparency pre-render but when I render the frame, you see a bunch of black planes. I am confused as to how this is happening. Any suggestions?

no idea based on those images, can you post the scene file?

I enabled the alpha channel in the render settings and it is rendering fine. Not sure how it became unchecked.

The problem is back. Have no clue what is going on. Here is the project file with the .avi file.

I broke the avi into a sequence of PNGs (which it appeared to be in the material) which took took it from 5.96 GB for the AVI to 15 MB for the 749 images (just a note for the future).
The file is made of 23 planes which need to be transparent for the effect to work but the Ray Depth of the project is set to 6. It’s usually set to 15 (in R20 anyway) so there are not a lot useless depth calculations going on when they are not needed but you need them. Ray Depth needs to be more than 23, 24 works but would have to go higher if you add more transparent layer that are all going to lie over each other in the shot. -
Wow Brian, I never would have figured this out. Thank you SO much! It works perfectly now so I can start fine tuning everything.
