Is this to do with "undo levels" taking up memory? The restart would not have 
undo level caches filled so that might be available .... the test might be to 
simply head into preferences and drop undo levels to none. However, I'm only 
guessing and have no idea how that works anyway.

  That's some forest Arjo, thanks for showing!

  Interesting trick to use a twig texture instead of a single leaf, you also 
see similar methods in games.

  A tip for big complex plant builders:
  If you get a message like 'cannot allocate ..... bytes' , try to save your 
project, quit RS, restart and load and try to render again. Open the task 
manager and watch memory consumption and swap file during 'processing objects' 
to determine if it's really a memory problem.

  Yesterday I managed to render a project with 7 instances of an old tree that 
failed to render before, and with decent speed. Is it the new SP, or did I give 
up too soon? Whatever, it's a great tool with endless possibilities.

    Hi,

     

    Nice trees Mark!

     

    Here's my wip. There are 22500 trees in this scene

     

    www.xs4all.nl/~joly/temp/forest.jpg

     

    It's nothing much yet, just experimenting.

     

    I chose a completely different approach to the tree. It has no individual 
leaves but rather a texture of complete twigs with leaves on a polygon.

    After creating the tree I exported it as obj to minimize the number of 
faces in Polytrans.

    This way I got a tree containing about 3000 triangles. This is much easier 
to handle, doesn't require so much memory.

    Of course it's not as nice as real twigs, but the low memory usage has some 
obvious advantages.

     

    The tree I've been working on is not yet good enough, when I think it's 
worth sharing I'll post it.

    I have to find out what shape is best for the leaf object. It should not be 
a simple square polygon but it should mimic the bunch of twigs with the 
smallest amount of polygons possible. That should hide the cardboard effect a 
bit.

     

    Arjo.
