2. I have tried to export the scene to a .wrl file and convert it to maya file via wrl2ma, but when I open the finish converted maya file it always give me lots of error messages like this :

"Error: file: C:/Users/**/hemo_ribbon.ma line 116: setAttr: Too much data was provided. The last 173 elements were not used. // "

and this :"// Error: file: C:/Users/**/hemo_ribbon.ma line 13078: setAttr: Too much data was provided. The last 1193 elements were not used. // "

Is this a problem which happen during the export process of Chimera or some other reasons?
