mark points obtained by converting to marker are not animated

[shujiang liu]

Hello, I can see in the camera that the locator points I have tracked perfectly match the head, but when I use the locator to generate mkr points by covert to marker, I can see in the camera that only the last frame has been picked up and no other frame range has been picked up And it turns out that his translateX and Y values haven't changed at all

Hello Shujiang Liu,

Apologies for the late reply, I have been very busy recently.

Can you confirm if there is any error displayed in the Maya Script Editor?

For example, I seem to be getting the following error when I try to use the menu "mmSolver > Convert To Marker":

# Traceback (most recent call last):
#   File "C:\Users\username\Documents\maya\2022\modules\mayaMatchMoveSolver-0.4.6-maya2022-win64\python\mmSolver\tools\convertmarker\tool.py", line 147, in main
#     delete_static_anim_curves,
#   File "C:\Users\username\Documents\maya\2022\modules\mayaMatchMoveSolver-0.4.6-maya2022-win64\python\mmSolver\tools\convertmarker\lib.py", line 166, in create_markers_from_transforms
#     end_frame,

#     asNormalizedCoordinate=True,
#   File "<string>", line 2, in mmReprojection
# RuntimeError: Maya command error

I will look into this error.

Yes, my error is the same as yours.Then there is the question of whether the matching effect is good for the movement of the character, such as dancing. I am the matching head but the effect is not ideal after the settlement of the head and this is the settlement of the neck neck

Hi ShuJiang Liu,

I will fix that error, however there appears to be another error in the UI of the "Convert to Marker" tool. By default the Start frame is set to "1001" (but the UI doesn't show the value).

The fix is to set the Frame Range to Custom and manually type in the value of your frame range.

In my example below, the plate frame range is frame 0 to frame 231.

Hopefully manually setting the Frame Range to custom will allow you to work around the issue while I fix the underlying problem and then release v0.4.7.

Thanks,

David

I'm not exactly sure what you mean - I will try to answer.

mmSolver can be used to solve a body part as a rigid transform object.

You can do more advanced solving with deforming objects if you use rivets (using the classic "rivet.mel" script, and then enabling the "Evaluate Mesh Rivets" option in the Solver UI).

If you have a character dancing, that seems like a lot of work. You would need multiple 2D Markers per-limb, and witness cameras time-synced to the main camera footage to give you more angles of the dancing motion so you can more accurately place the objects in 3D space.

mmSolver tools and the solver can still help with such a task, however mmSolver will not be a one-click solution - it will be a lot of work.
