Maple Tree - Seasons Pack is; 2 .tgo models, with built-in 'season shaders', making 8 variations of this tree.
Each season's tree has a different leaf count/size/colour and all seasons are pre-set into each model at default settings. Simply visit the internal network of each model's 'parts shader' and select whichever 'season shader' you require.
The total size for 'tree 1' is about 26mb, and 'tree 2' is about 27mb, including all default image maps on loading so, they're not too
memory heavy at all.
Defaults settings are 'Summer', in both models.
