2 separate issues, first time testing this feature;
1) 'Previewing' the turntable camera position and rendered camera positions are different. The 1st frame of the animation is identical, mid-way the model almost goes off screen but is perfect in preview.
2) I set the number of passes to 1500, quality was excellent. When the turntable loads the next frame, it saves the render after 1 pass. Loads the third frame and renders at 1500 passes, then 1 pass again, etc. I ended up with 75 images at 1500 passes and 75 images at 1 pass.
