Flappy Octane

3D mode now uses a generated panoramic sky texture with projected fractal clouds and a sun halo, and the scene fog/background are matched to the horizon so distant terrain blends naturally into the sky.

Ring rims are now physical but recoverable: touching a ring tube pushes the car out and applies a bounce so you can clip a rim and still continue, and passing is only awarded when the car crosses the ring plane inside the hole.

The course centreline eases in from dead ahead so the first ring appears in front of the car, ring weaving and vertical swings ramp up from the start, and ring spacing now varies between tight clusters, normal gaps and long jumps for more varied runs.

The 3D scene now uses a dedicated Universal Render Pipeline 3D renderer so skybox, clouds and sun render correctly while 2D scenes continue using the 2D renderer.

The game manager now explicitly places the car at a safe spawn height and nose-up pitch at run start and increases the initial forward speed so the car no longer immediately falls into the ground before the first ring.

3D terrain mesh resolution was increased for smoother ridges and a new TerrainBlend shader now blends grass/forest/rock/snow by height and slope with noise-warped boundaries; the sun uses soft shadows and terrain and trees now cast and receive real shadows.

When a 3D run ends the music is paused/stopped and the music root is disabled so tracks don't auto-advance or continue playing after crash/game-over.

Hitting the valley floor or mountain faces now triggers game over by sampling the procedural terrain height under the car, so mountain collisions and valley impacts behave consistently.

Conifers were rebuilt with multiple tapered skirts and a round trunk, tree stands now use three foliage tints, and scatter objects (trees/rocks) cast shadows and receive terrain shading for a richer scene.

The first ring has been moved farther from the spawn for more reaction time, ring radii and spawn spacing now scale with score and include small per-ring variation so runs feel more dynamic.

The HUD no longer shows the kilometers-per-hour speed display in 3D mode.
