Hi,
 
I have a question regarding ImageModeler/MatcherMover. I have some prebuilt 3D building models of a real city and I would like to map real textures from a video sequence using Matchmover, does it allow import of existing 3D objects and texture map the images extracted from the video? Thanks in advance for any suggestion/comments!

Do you really want to map animated textures on your 3D building? Or do you want to extract a single texture from one image of the video?
If you simply want to extract a texture, you can, in ImageModeler import a scene from MatchMover and select only a few frames. Import your 3D building in IM align it in your scene and extract the texture.
If you want to create animated textures, IM and MM do not provide this feature. You'll have to create this effect from your 3D or your compositing package.
