I wish I had the time to explain in detail but i don't so in bullet points this is what U gotta do in blender to fix animations and texture:
1. Append the armature from the Pyria template to your blender file and apply it (as a modifier) to your mesh
2. Edit the armature (don't add or delete bones) to fit your mesh and weight-paint as necessary. Only focus on the major bones.
3. Rename the applied material to match your texture, e.g. coolmarine.jpg.
4. Export the static mesh OVERWRITING the pyria.smd file in the "new animations" folder.
5. Execute the compile-zym.bat file in the "new animations" folder and pyria.zym should appear. Rename as necessary and place in the Nexuiz\data\models\player\ folder.
Bon chance!
P.S. the animations are stored in the other smd files in the "new animations" folder so your soldier will run like a girl.
