A repeating, scrolling texture can add visual interest to a static background. This example demonstrates how to create an infinitely tiling background using a model quad with a repeating texture. The effect is achieved by scrolling the UV coordinates over time, creating smooth, continuous motion.

The script driving the effect works as follows:

• Each frame it reads the current window size and scales the background game object so the quad covers the full viewport. The rotation is set via euler.z (Rotation Z in the IDE).
• It converts the window size into a UV repeat scale (uv_params.x/y) so the texture tiles across the screen.
• It advances a scrolling offset based on scroll_speed and tile_size, wraps it to the 0..1 range, and sends uv_params to the model material.
