Hi Guys, We are animating a simple ball flying all over the place. We would then like to take the motion path of the ball and convert it to a curve to create some solid geometry like trails. Is there a way to create a curve from the motion path of an object? Thanks. ---

here’s an old script… select object and calculate motion path, then run script from a text editor ```auto ## path from -calculated- motion path import bpy ob = bpy.context.object mp = ob.motion_path if mp: path = bpy.data.curves.new('path','CURVE') curve = bpy.data.objects.new('Curve',path) bpy.context.scene.objects.link(curve) path.dimensions = '3D' spline = path.splines.new('BEZIER') spline.bezier_points.add(len(mp.points)-1) for i,o in enumerate(spline.bezier_points): o.co = mp.points[i].co o.handle_right_type = 'AUTO' o.handle_left_type = 'AUTO' ``` ---

That was awesome. Thank you very much for the help. If you ever stop by New Jersey, I owe you a beer. ---

Yeah, I just realized that. Sorry, can the mod move it for me? ---

Yes, just ask one to do so. ---

I am using Blender 2.91 - > Traceback (most recent call last): > File “WizardGhost\Text”, line 11, in > AttributeError: ‘bpy\_prop\_collection’ object has no attribute ‘link’ > Error: Python script failed, check the message in the system console ---

it should be a simple fix, add ‘collection’ to that line, like …context.scene.collection.objects… ```auto ## path from -calculated- motion path import bpy ob = bpy.context.object mp = ob.motion_path if mp: path = bpy.data.curves.new('path','CURVE') curve = bpy.data.objects.new('Curve',path) bpy.context.scene.collection.objects.link(curve) path.dimensions = '3D' spline = path.splines.new('BEZIER') spline.bezier_points.add(len(mp.points)-1) for i,o in enumerate(spline.bezier_points): o.co = mp.points[i].co o.handle_right_type = 'AUTO' o.handle_left_type = 'AUTO' ``` hope it helps ---

well, first your object should be animated, so you can go to object properties panel \> motion path \> calculate then make a new ‘text editor’ window, create a new text and paste the script there… or use scripting worspace now, with your object selected, run script from text editor window and it should generate a curve object… ![bakepath](https://blenderartists.org/uploads/default/original/4X/b/b/d/bbdeb14169c903a0a7c021b51b399ae5fd1167ce.jpeg) ---
