Turn off "Progressive" on Renderer sub menu (left Tab),and now you can see "Bucket size" menu appear on Sub menu off Optimization (Right Tab). Bucket size is similiar to Region Divison. I hope this can solve your problem. i'm sorry for my bad english...

Can you give me some explanation, and help me to solve the dashed line or disappear lines problems ?
O Yeah My Computer Use 512 of RAM, Windows XP, SketchUp 6, GeForce 7200

why I use some realistic tree, because if I use 3D component from Sketch Up file become bigger n heavy for my computer , and I don't use adobe photoshop for editing. I make some picture of trees to be 2D component (of course I make some outline to result nice shadow )
