1. when i import a dae in lumion, the libfiles are placed in the main folder 'library'
True, this happens when Lumion first imports a new mesh from a source file such as dae. It has a default folder location where everything is placed - the root folder being \Library
3. i created a new subfolder and moved 3 lib files ( lib, lib.inn and lib.txx. ) of one object into this subfolder
but lumion doesnot show the object there, even after restarting
Strange. It should have worked OK, even if oyu had Lumion open and you did the moving in Explorer, once oyu shutdown and re-run Lumion and go to the Library menu it re-reads the files and builds the thumbnail list so you should have seen it in the correct place.
However, there are two cases where it won't:
1. if the files are copied rather than moved, creating a duplicate set of files, and they retain the same file name, then its the first instance of the objects file that Lumion reads will be shown in the Library (and the second is ignored).
2. if the 'subfolder' is only a subfolder of an existing subfolder eg \Library\folderA new \Library\folderA\folderAsub1 instead of \Library\folder then it appears within the base subfolder Tab group.
Each subfolder (1 level down only) of \Library get their own Tab (limited to (was 9)).
All files belonging to the subfolder and any subfolders at lower levels are read and populate the thumbnail Library display of 28 objects and further for additional slots (and the number of slots is limited as well 19 I think but don't quote me).
So all these files are in no specific order, the only order is the top level folders.
how can i sort imported files in the library then?
how can organize my library in subfolders???
Sort of answered in above, only to the level of first subfolder, ( 'sort' meaning organised in a grouping).
I use subfolders for each project, then once its completed, archive it or move it out of the \Library root to make way for new projects, plus keep a set of folders&subs for generic objects. Each time a new imported model is done I then maintain my Windows folders and files by moving things into their respective project folders (aftehr the end of a Lumion session). Not needed but that's how I like to organise things.
4. interesting behaviour in 'reload object'
when you replace an object you can alt+reload, and it changes the object in the library, means, the old object is overwrittenp
so , if files in the library folder can be organized in subfolders, is reloading after moving them still possible ?
Yes it is. Think in terms of master (one only) objects. Lumion reads all files to build its list of master objects, it knows where in the folder structure it is (in basic terms) and any updates to materials you make or reloads or new reloads(Alt+) update this unique/master and thus the files.
1. organise your files as needed, Lumion Import Library was designed to take a slightly different and project/object based focus rather than what most are used to of a resource-file and folder based organisation.
2. if you are doing maintenance of files to keep things organised as you like them/the way you are used to doing in so many other things, only do that once you have closed Lumion down.
