Easy Road System( Generator )
Are there any critical rules I need to follow to prevent the system from breaking?
To keep the procedural engine running flawlessly, there are just two golden rules to keep in mind: Do not rename any of the generated objects or collections, as the underlying node network relies on these specific names to target and instance assets. Always select the main Road mesh in order to see and adjust the parameters in your modifier panel.
How does "Preview Mode" help with viewport performance in large scenes?
Preview Mode is specifically designed to keep your Blender viewport butter-smooth. When active, it temporarily bypasses all heavy procedural details (such as scattered leaves, rocks, and high-poly guardrails) and displays only the clean road mesh. This allows you to draw, edit, and tweak your paths in real-time with zero lag. Once you are satisfied with your layout, simply switch to Final Mode to instantly reactivate all cinematic details for rendering.
