Generating texture with multi UV tile

[kguntuku]

Hi,
we recently bought Agisoft standard edition.
I made a model of an interior space from the photographs.
However I have a query regarding generating textures.
I  generated a 16K texture for the whole space and was thinking
of reprojecting it on the low res meshes in maya.
However the even at that resolution the detail is low.
Is there way to generate texture for multi tile UV.
what exactly does the texture size/ count do ?
will it generate additional tiles ? if so at UV space more than 0-1 ?
Any information on this will be highly appreciated.

Thanks again
