    Problem with rotation points after adding shading to Illustrator objects

    ssycko

      So I'm revisiting a project, and I just sat down to add some new shading to the characters in Illustrator.  All I did was add new shapes on the same layer as the object to get that really basic shading down, I just thought that I could reimport it and all the animations I already have would work fine.  Apparently not so.

       

      The first character I shaded, I just went straight through and shaded every body part, then went into After Effects to see how it worked.  I expected the walk cycles to get messed up, but I had had that happen before and all it took was a simple reimport of the layers to set everything back to normal.  It didn't work this time, no matter if I set the layer to "Document size" or "Layer size."  Here's what it looked like pre-shading:

      And after:

      There were different permutations of awful depending on how I combined the document size and layer size setting.  Every other composition that had this character animated in it are just as bad.

       

      I wasn't sure what caused this, so I decided to take another character, and just shade one part (his body).  Did so, imported it, same deal.  Before:

      and after shading just one layer:

      I have no clue why this happened, I figured since After Effects just references the Illustrator files that all would be fine after some reimporting.  Does anybody know why this happens/ how I can fix it?

          What excactly is involved in "shading"? If you use gradients, then that's where your problem comes from. There is an issue in Illustrator CS4 itself, where it will define the bounding box of a layer based on the placement of the gradient annotator even if it's way outside the path/ object instead correctly clipping to the object path. This also causes trouble in other areas. Nothing you can do about it. You would have to expand the appearance or use gradient meshes. Since you seem to be working at a fixed resolution, anyway, you might also want to do this in Photoshop and replace your AI layers with PS layers.

            The shading isn't gradients.  I actually tried them out for about 2 seconds and then got rid of them, all I did was add 2 seperate shapes/paths/whatever the technical term is (shadow and highlight).  Both shapes are just fill, no stroke.  When I read that gradients would have caused an issue I first thought maybe it was a residual problem from trying them out for a bit, but then the same problem happened when I just added one extra shape onto the red dinosaur without touching gradients.

              That's odd. I'm realyl only aware of this one specific issue. Do you use open paths anywhere? Do you use clipping masks? Compound paths? Live effects? Anything that may extend an objects bounding box? Do you run the latest 9.0.2 version of AE? There was aan issue with importing cropped layers that only got fixed in this update...

                Sorry for taking so long on the response, I've been away from this project for a little while.   I just checked, I'm indeed running 9.0.2, and I'm not using anything other than closed shapes on each body part layer.  I think the reason why the body layer keeps splitting even though it's a solid shape, it has puppet points on it and for some reason instead of just moving the body around it tears it from the rest of the body.

                 

                This is terribly frustrating.
