Kevin,
>> How does one make these trees into single objects (easy to move <<
the Schreiber trees are broken up into multiple objects for one simple reason:
3ds has a 64k face limit and the program makes a new object when it needs to
stay below that number. Move them as a selection.
>> I've got a P-90 w/32M RAM. I would think that I should be able to generate a
stupid tree. <<
Not necessarily. The trees can be so geometrically dense that it's easy to
exceed that amount of RAM. We've used Schreiber's Nursery extensively recently
and had good luck with it – certainly no crashes come to mind. We do have
128-196mb RAM on our systems which may help. Also, be sure to check with
Schreiber to ensure you have the latest version – the first version exhibited
that instability for me too (some years ago) and may have been fixed.
