    After Effect Composition turns black

    catrianty

      Hello, I have a problem with my AE composition. I've been importing new layers to my AE composition, however suddenly the composition screen turns black. All the keyframes are still there and as I slide the button across the timeline, I can see the keyframes are still there. I tried undo-ing my steps to see if I made a mistake that rendered the screen all black, but no luck. I assume I might have accidentally clicked a function/view that triggers the screen to turn black, but I'm not sure what function that was. I also first thought I activated the wireframe view but as I switched it back to the normal view, still no luck.

       

      If anybody could help me troubleshoot this problem, that would be great. Thank you so much I'd really appreciate it.

          That's a prretty small scren grab for diagnostic use.  I can't make out the layer names & such.  Only one question I have at the moment: what's in layers 1 through 28?

            Hi Dave, thank you for your reply. I have provided a larger screenshot for your convenience. Layer 1 through 28?

              One more thing. This is what the comp looks like when I highlight all the layers. All the keyframes and animation are there but the layers are invisible, just some guides and bounding boxes.

                I have a couple of questions. Did you import your Illustrator file as a composition retaining layer sizes or are all of those layers separate .ai files?

                 

                Here's another question: What happens if you solo a layer? How about purge all caches? What is your fast previews setting?

                  Hi Rick, thank you for your reply.

                  I imported my illustrator file as a composition retaining layer size. However, I keep on updating and adding more layers in the illustrator file, so everytime I added a new layer in Illustrator, I imported it as a Footoage > Layer Options > Choose Layers and that's when I added the new layers from Illustrator to AE.

                   

                  Nothing happened when I solo a layer and purged all caches. The following is my fast previews setting

                    Try starting a new composition and import your new AI file as a comp. See if your comp works then.

                     

                    It's not usually a very good idea to add layers to an existing Illustrator document imported as a comp. I'd start a new AI file for your new assets.

                     

                    Also, in your second screenshot I see a whole bunch of layers extending outside the comp boundary. This brings up a question about the canvas size in AI. Objects outside the canvas are cropped to the artboard so I must ask, did you change the artboard size?

                     

                    I also see that you have not turned on transparency grid. What happens if you do that.

                     

                    One last question about this asset

                    According to the info palette this layer is 1 X 1 pixel. That's a pretty useless layer size in a comp. If the middle bar layer isn't positioned precisely on the pixel grid then you'll end up with something that looks like this (the light tan - Note the position and the anchor point) :

                    Notice what happens when I try and line up a one pixel high (or wide or both) illustrator layer with the pixel grid as compared with a 1 X 1 white solid.

                    There's a bug in AE that causes odd number of pixel wide or high vector objects to be interpreted just slightly bigger. Note the anchor point in the previous example (0.8, 0.8). This tells you that AE is interpreting the layer size as 1.6 pixels by 1.6 pixels. That means nothing is going to line up ever. If you really intend your design to have a 1 pixel by any dimension shape and have it line up you must create that shape .7 points in AI. AE will interpret it as 2 pixels high or wide but it will display as one pixel and you will be able to line it up with the pixel grid....

                    I'm assuming that you already know about fixing the anchor point of odd sized layers so that they line up on the pixel grid. This is critical when creating very fine lines and detail that you want to use in a design. For example, if you had a shape layer that was 1 pixel by 1 pixel the anchor point would default to 0.5, 0.5 so you would have to change that to 0,0 or 1,1 to get the shape to line up on the pixel grid.

                     

                    I still don't know why your project went black. Maybe there is a problem with a single new layer you created. Maybe there is a problem with a bunch of 1 X 1 pixel layers.

                     

                    By the  way, I thought I should mention that if you convert your vector layer to a path you will get a path that is exactly 1 pixel by 1 pixel but position of the path will have to be adjusted to get it to line up with the pixel grid. The lesson here is that if you really want to use very thin lines in a design then  you should use the shape tools.

                      Empty your cache in AE. Then restart your computer and open after Effects. Should be back to normal.

                          Hey make sure caps lock is not on that will also give you the black screen, not sure if that was mentioned but I just noticed it.Screen Shot 2016-10-17 at 3.10.10 AM.png

                          caps lock off
