Transferring clip from After Effects to Premier Pro issue

So, you've done all the work in After Effects and now want to edit it?  As Mylenium says, the ideal workflow is the other way around, that way you only apply effects to the elements in your final edit.  But seeing as you've already got it looking right in AE, render out the composition using an Apple ProRes codec.  You can then drop this into Premiere Pro and add the final touches.

You seem to misunderstand the workflow. You don't export a Premiere Project, you render a clip or replace the source clip with an AE composition via DynamicLink. Otherwise if there are other issue you have to be more specific and provide screenshots and better explanations of what you actually do. There's just too many ways to make stuff in AE not show up from inadvertently having toggled soem layer switch or turned off an effect to working at odd zoom levels that make predicting results hard to using wrong render settings to genuine issues with e.g. hardware acceleration functions this could be a million things.
