I working on a after effects(CS3 ) project that was started by a another designer and when I open the project I get a "this project contains 1 reference to a missing effect.Please install the following effect to restore this reference. (Inner Bevel")
Not related to AE. AE does not have an Inner Bevel effect. The designer probably was using third-party plug-ins like Boris Continuum Complete or such. Since it's CS3, you may however be able to re-create the look using layer styles. You'd still need a reference image, though, as I consider it very likely that identical values have a different meaning in the layer style than they would have in the plug-in. Therefore a phone call to the person is unescapable, if only to confirm my theory. If he can tell you, what plug-in he used, you should at least be able to obtain the demo version of it and use it as a reference.
