Commit: 85e8de234b15d9d756c75912b6d8bf5d92dd4fc0 Author: Alexander Gavrilov Date: Mon May 3 17:27:53 2021 +0300 Branches: temp-angavrilov https://developer.blender.org/rB85e8de234b15d9d756c75912b6d8bf5d92dd4fc0
Animation: support filtering for curves that have cycle issues. It is possible to have curves with cyclic extrapolation that have a mismatch in their end keyframes, causing a jump. Also, since the looping behavior is defined per curve rather than at action level, it is possible for curve loop periods to get out of sync with each other. This commit adds an option to compare curves against the manual frame range specified in the action, and treat any mismatches as errors for the purpose of F-Curve filtering. When enabled, the check verifies that end values of cyclic curves match, curves within a cyclic action have valid cyclic extrapolation, and the action period evenly divides by the curve period (since a curve looping at e.g. half of the action period length still repeats in sync with the action).
