Type:float array of 3 items in [-inf, inf], default (0.0, 0.0, 0.0)
texspace_size

Texture space size

Type:float array of 3 items in [-inf, inf], default (0.0, 0.0, 0.0)
twist_mode

The type of tilt calculation for 3D Curves

  • Z_UP Z-Up, Use Z-Up axis to calculate the curve twist at each point.
