Animation import issue

(Rubiez) #1

there seems to be an error with calculating the joints.

I have seen this model in multiple applications and game engines and it works perfectly.

you can see the problem in the link below:

from a second look, it seems as if the joints on the big arms, got parented to the joints on the small arms

Animation imports incorrectly

What did you export from? I've had luck saving out my animations from Motion Builder as ASCII fbx format with default settings and uploading them onto sketchfab.

first atempt was binary using maya 2014. then i took your advice and uploaded it as asci default... it got worst... now he's twitching like crazy

(Shawnbel) #4

Did you save it out from Motion Builder? or did you export it from Maya again as ascii??

(Rubiez) #5

Okay,you where right, problem solved smile

for some reason it seems that mayas .fbx files are not very compatible with sketchfab...

all i did was opening the animation in motion builder and saving as an ASCII fbx...and that solved it.

thanks smile

Awesome. No problem. It has been my consistent solution so far!

Thanks @rubiez for your report and also thanks @shawnbel for answering and having given this workaround.
To give you more details about it, the issue occurs for a skeleton where several bones have the same name.
It appears that some softwares take care of this case by renaming the duplicates during the import/export operations, that explains that using MotionBuilder fixes the issue.

A fix is on its way in our side and will be included the next release, so you will not have to use this workaround anymore smile
