  • Linking ramp effect to unrasterized vector that sits on a 3d layer

    Posted by Dennis Dillert on April 21, 2009 at 5:28 pm

    Hi guys,

    I have a 3d scene where I have a vector graphic in the middle with a ramp effect applied to it. If I leave it as a rasterized graphic, everything works fine. However, if I want to maintain the vector information, it somehow messes up the ramp. The ramp now seems to be applied to the camera (or global coordinates?), not the object itself, because if I move the camera in 3d space, it affects the ramp effect and moves the transition parameters of the object.

    How can I link the ramp effect to the object in 3d space or is this a bug?

    I uploaded a file to https://rapidshare.com/files/224071442/ramp-effect.zip.html. Extract it to your desktop and try to move the camera in y to see what I mean!

    Thanks
    Dennis

    I’m using After Effects CS3

    There are a couple of things that happen when you continuously rasterize a layer: the render order changes within the layer, and the items (like effect control points) that were measured in layer space are converted to composition space.

    Here’s a relevant excerpt from the “Continuously rasterize a layer containing vector graphics” section of After Effects Help:

    “When you apply an effect to a continuously rasterized layer, the results may differ from the results of applying the effect to a layer without continuous rasterization. This difference in results is because the default rendering order for the layer changes. The default rendering order for a layer without continuous rasterization is masks, followed by effects, and then transformations; whereas the default rendering order for a continuously rasterized layer is masks, followed by transformations, and then effects.”

    To force transforms to happen after effects for a continuously rasterized layer, you can use the Transform effect, or you can precompose the layer(s) with the effects and then animate the transforms of the precomposition layer.

    Thanks Dave, I tried that and it worked magic. Any chance to get the precomped layer to the original size of the object itself? Tried masks, but then the mask handles seem to be in the way in the original comp!

    Thanks Todd. I’m using a camera movement in y, so the only option seems to be precomp layers.

    Many thanks to both of you!
