'From this day forward you are able to take your 3D render and replace textures or even add reflections and environment. In a nutshell all you need to do is to apply the Youveelizer to a layer with a UV render pass to apply a texture to a rendered 3d object, or to a Normal render pass to add reflections. All 3d objects should be rendered out from a 3d application such as 3d Studio Max, Maxon Cinema 4D, or any other 3d package capable of rendering UV and Normal render passes. However it’s sometimes difficult to render out a nice UV pass. A solution to that problem may be simply applying a texture that simulates a good UV map. That’s why I’ve included a nice 2000×2000 pixels “uvmap_texture.tif” in the product package.'

"RE:Vision's Re:Map also does this sort of thing [UV mapping & more], although I haven't watched Maltannon's tutorial yet to see if they work the same way. Always good to have more (and cheaper!) options!"

Still missing an Ambient Occlusion plugin for After Effects, any news on that issue?
I'll keep an eye out but you should mention this to Maltaannon and to Stefan Minning, who made Normality.

How would you see Ambient Occlusion plugin for AE? If you want to apply the Ambient Occlusion to a render you simply take the Ambient Occlusion pass and multiply it with the render. If you want to render an Ambient Occlusion pass from After Effects you can't really do that, since AE does not read 3d mesh data - only flat pixels, therefore it cannot generate Ambient Occlusion. However you can try to simulate that using Normality and a light, but the results will not be as accurate.
For anyone interested in ambient occlusion in After Effects, I'm currently working on a plug-in to do just that: http://www.minning.de/software/occlusionist
