Texturing the tracks

We will now create a texture for the tracks using a slightly different node setup:

1. First, create an Edge Mask for the track object:

2. Add a Mix RGB node between the Edge Mask and the Principled BSDF node:

3. Plug a Noise Texture node and a ColorRamp node into the Mix RGB node:

4. Add a Node Wrangler to the Noise Texture node by selecting it, pressing Ctrl + T, and using the UV output.

This will correct the projection of the noise texture. Note that we have also adjusted the settings in the Noise Texture node:

5. Use the plus button to add a new marker in the ColorRamp node. This will create a multi-colored texture on the track:
