Hi bloodsong, i didn't find the tutorial for what i wanted to do. The lizardman actually call (need) 3 .obj files. it will be better if it were one only. I turn off visible some body parts. To make him walking correctly with walk designer or any other poses,i had to block some body parts like human hip, human abdomen and human neck. The bottom of the raptor is the parent. The human's hip is a child of raptor's hip, and the raptor's neck is a child to te human's neck. Sorry for my bad english ;-) Thanks again.
