Animation problem

[Arian Shamil]

Hi!
When i start to render my animation Ks4 automatically deactivate detailed shadow, shadow on the ground and reflection on the ground.....why?
If i do a single render...everything works fine....
When i start to render the animation...KS4 deactivate by himself all these option...why?

This sounds strange. Did you activate performance mode?

Hi! The problem was given by having more than one Camera set on the same file...i've deleted all the camera sets and now everything works....i don't know why...
But at least now it works well

I have a similar problem - I hit the animate button > and the screen either goes black or nothing happens.  I'm just learning animation so it may be something I'm doing. It's in Performance mode and I've deleted all Cameras except 1.
