<member name="bake_interval" type="float" setter="set_bake_interval" getter="get_bake_interval" default="0.2">
The distance in meters between two adjacent cached points. Changing it forces the cache to be recomputed the next time the [method get_baked_points] or [method get_baked_length] function is called. The smaller the distance, the more points in the cache and the more memory it will consume, so use with care.

If [code]true[/code], and the curve has more than 2 control points, the last point and the first one will be connected in a loop.
