3.1.Mesh preparation #

Any mesh you wish to deform along a spline needs to meet a few basic standards.


Unity uses a left-handed coordinate system. This means that the Z-axis is considered the forward/back direction, the Y-axis up/down, and the X-axis right/left.

Basically, assets that are to be used in Unity already need to adhere to this standard. Using a child-object and rotating it -90 on the X-axis is considered bad practice, and does not work in the context of reading a mesh’s data.

DCC’s such as Blender and 3DSMax use a right-handed coordinate system (Z-axis up). They’ll have an incorrect orientation out-of-the-box.

Please refer to their manuals for correct export settings.


Because the mesh needs to be able to bend, it requires a topology that allows for this.

If it has long faces adding a few subdivions is sufficient.
