Hi,
you can reverse the animation from Navigator/your_character/character controls/solving/mirror animation, then you can replot it to a new clip and mix with the unmirrored one.

Hi,
I am using MB 6.0.1, but it should be somewhere under Character settings. Check out the attached picture. Let me know if you have any further problems I’ll be back online tomorrow.

Hi again

and i m using MB 7.5 but the mirror option is in the character’s general option u can check out the attached picture ,and i used the mirror option but the whole animation was mirrored which i dont want , is it possible that i use mirror option on my half animation ?

You can make a new take, mirror the data and plot it to the new take… then just copy the keys for the mirrored part and paste it back on the first take.

or you could mirror the data and make a clip of it in story and then blend the two moves in the story tool.

Yep,
as bclark said mirror and plot the animation to the new take. Import the unmirrored clip into your character track in Story, make subtrack (override) import mirrored clip into that and choose the bodyparts you want that track to use.

Hi,
off the work…
How are you retargeting the original motion, from animated skeleton or are you using story?
Can you give a short description on the workflow you are using and the original motion file?

well my workflow is

1) make a model and rig in Maya.
2) import in to motion builder.
3) characterized .
4) use story for animation.
5) drag the animation from Asset Brwoser / Templates / gobo / General / Super Hero.
6) plot the animation for manual key framing.
7) make new layer.
8) add some manual Keys.
9) Plot the Character from the Navigator option.
10) save in Fbx formate.
11) import in to Maya again.

Hi,
once you have plotted the first unmirrored clip to your rig create a new take and plot another clip with the mirror animation button pressed. Create a character track and right click to bring take1 (unmirrored) to the track, now create override sudtrack, choose take2 and bring that to the subtrack. For the subtrack choose just the lower body or just the foot you want that track to have influence on. Move the mirrored clip to match the timing of the original animation. Then process the whole scene back to your rig and exit story mode.
Hope these tips get a step forward,
good luck,

heloo

i tried as u explained but its not working :frowning: because i m using MB 7.5 version and u r using MB 6.5 thats why i m not able to send u the MB file , could u plz explain me step by step if its possible :slight_smile:

thanks in advanced :slight_smile:

Hi,
if you mail me the file I could try converting it with FBX converter and take a look at it. It is a bit easier to break the problem in pieces when you actually see it.

hi anssi

actually its not a particular file u can test on MB’s default characters aswell, u already know that obviously. ok wht i want is …

  1. open any character.
  2. characterized the character.
  3. drag H_RunJump clip in to story from Generic/SuperHero section.
  4. when u import the clip u’ll see your character jumps after run .

When my character jump and run i need its loop but not the same , means first my character run then jump by his right leg then run again, after run he jump again but this time he jump by his left leg how its possible i hope u got my point

…
4) press mirror animation from character settings (it should turn the run to other direction)
5) in Story right click on the track (left side) it gives option Process tracks/subtracks to a new clip …save it and name it run2jump mirrored…and you should have to Char tracks
6) turn the mirror animation off
7) cut the new processed / mirrored clip to the first Char track or drag it from asset browser and delete the Char track one
8) change the view mode to x-ray and press the eye icon to view ghosting
9) match the clips in time and space (use match object for precision)
10) use subtracks to fix / alter the animation if needed
11) plot the whole animation to rig / skeleton

Million ways to do it here is one,
good luck,
Anssi
