Probuilder Unity 2019

You can create straight stairs, curved stairs, long stairs, stairs with a lot of steps, wide stairs, and stairs without side polygons.

Probuilder Unitypackage

You can customize the shape of your stairs with these shape-specific properties:

Probuilder Unity

Property:		Description:
Steps Generation		Select whether you want ProBuilder to build the same number of steps regardless of how the size of the stairs changes (the default) or make each step the same height and automatically adapt the number of steps to match the stairs size.
Height	Select this method if you want ProBuilder to generate a predictable height for each step in the staircase. This means that if you increase the height of the overall size of the staircase, the number of steps increases.
Count	Select this method if you want ProBuilder to generate a specific number of steps, regardless of any changes in the size of the staircase. This means that if you increase the height of the overall size of the stairs, each step becomes higher. This is the default value.
Steps Height		Set the fixed height of each step on the stairs. The default value is 0.2. This property is only available when the Steps Generation method is set to Height.
Homogeneous Steps		Enable this option to force every step to be the exactly the same height. This is enabled by default. If disabled, the height of the last step is smaller than the others depending on the remaining height. This property is only available when the Steps Generation method is set to Height.
Steps Count		Set the fixed number of steps that the stairs always has. The default value is 10. Valid values range from 1 to 256. This property is only available when the Steps Generation method is set to Count.
Sides		Enable this option to draw polygons on the sides of the stairs. This is enabled by default. You can disable this option if the sides of your stairs are not visible to the camera (for example, if your stairs are built into a wall).
Circumference		Set the degree of curvature on the stairs in degrees, where 0 makes straight stairs and 360 makes stairs in a complete circle. Remember that you might need to increase the number of stairs to compensate as you increase this value. The default value is 0. Valid values range from -360 (full turn to the left) to 360 (full turn to the right).
