I wanted to make the air strip in FS2004 look more like the real bush strip that I fly into, so I added about a hundred tree macros. I made 2 polygon trees, like the ones that FS9 uses, in FSSDesign but my frame rate dropped dramatically. Is there a better way to add lots of trees without affecting the frame rate so badly? Thanks

You could try using my Trees Library, which you can download from here as trees_v3.zip. Once you have downloaded it, e-mail me direct to register and I'll give you any other help/advice you need.CheersGerrish

Hello Thomas,One possible problem, although I do not know if it applies here, is the size of the textures used. The default autogen trees use very small textures. If you are using large high-resolution textures, you can get a significant impact on frame rates.Gerrish has often pointed out that the size and quantity of textures are the principal obstacle to good frame rates.Best regards.Luis
