The maximum amount each bone can rotate in a single iteration.
[b]Note:[/b] This limitation is applied during each iteration. For example, if [member max_iterations] is [code]4[/code] and [member angular_delta_limit] is [code]5[/code] degrees, the maximum rotation possible in a single frame is [code]20[/code] degrees.

If [code]false[/code], the result is calculated from the previous frame's [IterateIK3D] result as the initial state.
If [code]true[/code], the previous frame's [IterateIK3D] result is discarded. At this point, the new result is calculated from the bone pose excluding the [IterateIK3D] as the initial state. This means the result will be always equal as long as the target position and the previous bone pose are the same. However, if [member angular_delta_limit] and [member max_iterations] are set too small, the end bone of the chain will never reach the target.

The number of iteration loops used by the IK solver to produce more accurate results.
