Finally I created my own character, the problem now is that sapien won´t create the biped or the character, everytime that i Try to put my custom biped it says:

OUT OF OBJECTS: Cannpt Create Extrangulador

When I start sapien i got this messages:

###The biped extrangulador\extrangulador has no "Head" marker
###The biped extrangulador\extrangulador has no "Body" marker

In the animation graph, I used the captain keyes "Model animation tag" because my custom character was taked from captain keyes.gbxmodel

The object extrangulador\extrangulador will not animate.

Info:
*The character, is bigger that a "cyborg" (Master chief) ¿Thats the problem?
*While compiling the collision-geometry, tool showed me this error
###ERROR found z buffered triangles
WARNING found some coplanar surfaces
I imported the .wrl file but the Z buffered error and the coplanar surfaces are inside the character, so I think nothing wrong will happen.

Did you give your model the node checksum of the collision model (keyes)?
