I have been charged with creating a scene for my historical documentary club - I have to create a 1700s fort from scratch and the surrounding countryside. I've got the basics done, but I really need to create hundreds of trees. I have created 200 copies with the replicate function, but as this takes up too much RAM, I am unable to save whatever I do...too many polygons I suppose. Is there any other way to create a forest or 3D illusion of thousands of trees? This isn't just for a still shot, it will include camera movements in 360 degrees. |

Actually for Bryce. My club invested $100 in Bryce 6, so we're stuck with that until I can convince them to upgrade next year. But in all seriousness, I'm the only one who halfway knows how to use all the programs I installed on the Mac, so I think we're going to stick with Bryce for its simplicity. I'm rambling, and yes this is for Bryce.

hmm in that case im really not sure. I used bryce for about 2 months then moved on to 3ds max. I never really looked back after that. But I imagine that there is a limit to how much detail you can force on the program. A forest really wont be your friend in terms of rendering. As far as simulating or faking terrain I have no idea |

maybe You can do a less detailed trees in a background? It can speed up redndeting a bit. |

Maybe that will work...it's not a problem with rendering speed. It's simply the fact that Bryce will not save my work when a forest of 100 trees is in it...it runs out of RAM. Will using trees with less polygons work? |

i think that. in my solar movie most of a starfield were a low polygons models, only these close to the camera were hight, It really helped. There were about 400 asteroids? |

Lowering the quality wont lower the polygon count unless lowering the quality takes parts away from the trees. Say a tree has 2000 polygons, you lower the quality of it. It still has all its branches and leaves and the detail looks horrible. You will still have 2000 polygons on the tree. So if lowering detail removes the amount of leaves you will have a lower amount of polygons. If not then the only difference you get is faster rendering. |

^Almost. I'm talking about problems with saving because of too many complex objects, not the quality of the objects. Will finding objects of a lower polygon count solve the problem of running of of RAM while saving? Last I checked with Bryce running with 200 trees, it was using nearly 600MB of my gig of RAM. |

^Then I will need to find some tree models online. But I'm guessing that will be the best way to go about doing it. I think Bryce has some 2D trees that might work too. |

I used to have a list of models that can be downloaded for bryce but i cant think what it is anymore. I believe you can use 3ds files in bryce |

Lowering the render quality is not what will solve the problem of too many polygons... |

its been a while since i used bryce but lowering the polygon count will speed everything up you could even try to use a matte painting. i wll post an example of what i mean a prerender image from bryce and put your trees ontop of it. |
