Interesting! When I add a BakeMesh() call after all of my point updates, I receive this error when running in the Editor: Code (csharp): ArgumentException: shapeParams.splineDetail (0) must be within 4 - 32. UnityEngine.Experimental.U2D.SpriteShapeUtility.GenerateSpriteShape (UnityEngine.Experimental.U2D.SpriteShapeRenderer renderer, SpriteShapeParameters shapeParams, UnityEngine.Experimental.U2D.ShapeControlPoint points, UnityEngine.Experimental.U2D.SpriteShapeMetaData metaData, UnityEngine.Experimental.U2D.AngleRangeInfo angleRange, UnityEngine.Sprite sprites, UnityEngine.Sprite corners) UnityEngine.U2D.SpriteShapeController.BakeMesh (Boolean needUpdateSpriteArrays) (at C:/Users/nolen/AppData/Local/Unityfirstname.lastname@example.org/Runtime/SpriteShapeController.cs:292) UnityEngine.U2D.SpriteShapeController.BakeMesh () (at C:/Users/nolen/AppData/Local/Unityemail@example.com/Runtime/SpriteShapeController.cs:246) and then I see the same behavior exhibited during a build! My mesh has stopped updating its points visually, even though the game continues to run. My SpriteShapeController has had its Spline Detail set from Low through High Quality, with the error occurring regardless of value, and I've even attempted to set the value of the integer in my script as well. I'm curious if this could relate or possibly explain the build issues I'm seeing?
