rendering with maya software seems to be working so far... Only have about 30 frames done though. I don't feel completely sure yet, so I am still trying things...

someone on another message board said:
"maybe you had key framing set to auto and accidentally set a key frame on something (like visibility or cast shadows)."

Is there a way to delete all key frames from the scene?
I tried delete all by type "static channels"
would that work?
