problem import ColladaMaya animation with joints and skins

when i try to import a collada animation from maya with joints and skins i have these errors:

WARNING: Could not find a transform with SID=visibility
WARNING: Could not find a transform with SID=visibility
WARNING: Could not find a transform with SID=visibility2
WARNING: Could not find a transform with SID=visibility3
INFO: animations COMPLETE (#channels: 0 #frames: 0, startTime: 0 endTime: 0)

what’s the problem?

What COLLADA plug-in are you using ?
What application are you importing to ?

regards

i found the solution thanks for the answer me but i have an other problem is there a way to conserve smooth informations from a collada animation?

thanks

i use colladmaya plugin 3.05B

What was the solution you found?

The smoothness of animation is going to depend on the sampling frequency and the interpolation function used. Check your plug-in options for animation baking and re-sampling.
