Advanced Features

This section provides in-depth information about the advanced tools and workflows available in ICR.

🧬 Spline Path Deformation​

The Spline modifier allows you to bend the entire roofing system along a complex path.

Key Modes:​

  • X-axis Follow: The roof is deformed based on the X-coordinate of its vertices relative to the spline length.
  • Y-axis Follow: The roof follows the path along its length.
Path Smoothness

To achieve smooth results on curved paths, ensure that you increase the Segments per Panel in the Mesh Settings.

🌫 Surface Noise & Randomization​

Add organic imperfections and realism with the procedural noise engine.

  • Vertex Displacement: Noise is applied in local space before spline deformation, ensuring it "follows" the geometry correctly.
  • Panel Jitter: Small, randomized offsets in position and rotation prevent the "perfect" look of tiled assets.
  • Random Seed: Any change to the seed will completely refresh all randomized elements while maintaining the overall layout.

✂️ Global Cutting System​

Define precise clipping regions across your entire roof grid.

  • Non-destructive: Cuts are calculated during the vertex generation pass. You can change cut boundaries without losing data.
  • Coordinate System: Boundaries (Min X, Max X, Min Y, Max Y) are expressed in normalized global space (0 to 1).
    • Example: Setting Max X to 0.5 will cut the entire roof exactly in half along its width.

🏗 FBX Export & Optimization Workflow​

For high-performance production, you should convert your procedural roofs into static FBX assets.

Workflow:​

  1. Design: Adjust all parameters until the roof looks perfect in the scene.
  2. Create Asset: In the System & Export section, click New to create a target FBX file in your project.
  3. Bake: Click Bake Geometry to Asset. This will generate 3 separate meshes (LOD0, LOD1, LOD2) and save them inside the FBX.
  4. Switch to Preview: Enable Preview Baked Mesh. The InfiniteCorrugatedRoof component will stop generating procedural geometry and instead display the meshes from the FBX.
  5. Prefabbing: You can now safely drag your GameObject into a Prefab or move the FBX asset to other scenes.
Baked Mesh Format

The exported FBX includes vertex positions, normals, tangents, and a single set of UVs. It is optimized for standard Unity materials.
