Karts drive through surface or drives on a wall

This issue normally relates to transferring karts to new geographical objects. Kart's stick continuously to their current geographical object. Transferring to new geography requires the beginning of a new object running parallel to the old object or an aerial maneuver (ex. a jump).

Examples:

The first example below will result in the kart driving through the ramping geography keeping to its current ground. The second example displays good modelling for Mario Kart 64 because the original geographical object ends when the ramp begins. In other words, when a kart drives into the ramp the game will only have one option to use for ground; the ramp.

The following approach to modelling geography is the best practice:

Index out of range error

Normally due to a triangle being too long. Try splitting the longest triangles into multiple triangles.

Scaling issues or missing geometry

In blender press CTRL+A and click Apply Transformations. Experiment checking Apply Transform in export settings.

Render conflicts

In-game example:

In-editor example:

Observe that two separate objects are overlapping each other. Solve this by adding more vertices to the objects and connecting the vertices together:
