Hi,
Please note, that you can use any model inside the 3D Max scene as
Custom Object under
Geometry tab. So, if you
Merge (or link as
XRef) any model into your scene and then create
Forest object you can pick it as
Custom Object. Model linked as
XRef will be not saved within the scene and everytime needed the model is loaded from it´s external reference file.
Merge function will import whole geometry so the total size of the scene will increment of model size.
Anyway this process can be done easily in automatic way. For this purpose there is
XFrog Catalog linking all models through
Library Browser inside Forest Pack. Please check this
page about Forest Pack support for XFrog plants.
Anyway,
XFrog Catalog supports commercial plants packages so in case you have just free samples and you want to use
Library Browser to insert them, you´ll need to add them to your own personal library.
Here you can find instructions how to edit your personal libraries. Please also check this reference page describing functions of
Library Browser.
Also have a good news about Evermotion's Archmodels. We´ll release
Evermotion Catalog containing most used vegetation packages soon ...
Hope it helps you
