Crytek have released the first version of the Mod Software Development Kit for Crysis. Among loads of other good stuff, it contains updated versions of the CryENGINE2 Exporter and the PolyBump plugin for Max 8, 9 and 2008 (both 32-bit and 64-bit).

I always liked the polybump plugin for normalmapping, good results out of the box. There are a few changes to it since I last used it but it seems to do the trick
