  Question/Problem with 3d Grid/Video Wall tutorial by John Fischer

  Posted by Chopper06 on February 4, 2006 at 3:11 pm

  Hi, Im pretty much a newb when it comes to AE (im using version 5.0 unfortunately) but am trying to learn what i can through various books and tutorials. I was having a go at the 3D Grid/Video Screen tutorial (2003) and am having no success in getting the results i should. I do everything as described in the tutorial up until the point where it says ‘do a RAM preview, and you should get a nice flowing line effect.’ The preview is running but all i have is a black screen in the comp window. When i then try to go on and disregard this, and add the the Fractal Grid comp to the 3D grid comp, the ‘nice flowing line’ still fails to appear.

  Any ideas what i may be doing wrong? Is it an AE version problem because im using 5.0? Any help would be really appreciated. Sorry if this isnt enough info to be of use!
  Cheers

  It sounds like your computer doesn’t have enough RAM to produce the shot.

  I used to have this problem too, until I bought some more.

  Basically, Fractal Noise is a number cruncher. When After Effects needs to do something, but can’t handle the load, it produces a black screen.

  There is a solution however, (apart from parting with your hard-earned cash that is). Take just your fractal noise layer and render it out as a video file. Bring that back into After Effects and swap it for the original. Now the number crunching is done and AE can get back to compositiing.

  Hope that helps

  Hi Graham thanks for your response! Unfortunately this solution didnt work for me. I followed the tutorial again from scratch and then Rendered the layer, but it just produces a 220megabyte 5 second black screen (sounds ridiculous!)
  Im really not sure whats up with it now, i guess its something to do with my settings or version. I followed the tutorial to a ‘T’ as far as i can see…

  Thanks for your help anyway, i really appreciate it! Any other ideas? From anyone?

  Well my topic was mostly ignored apart from Graham’s attempt to help, but i thought id say i figured out the problem. The original tutorial says to make a ‘Layer’ at a certain point, when in fact it requires you to make a ‘Solid’. Or thats what worked for me anyway…
