Cujo explained it best. but when renderbale is unchecked in the camera atributes maya warns me before the render so I checked it and still the same prob. The render log says everything worked like it was suposed to but, well it didnt.

Pony it does play all 90 frames.

3djoe that is what I have my render globals set to but with the frame padding at 2. I will try setting it to 1.
thankyou all for your help. If you can thimk of anything else let me know.
