The title says it all. If not I hope the picture helps explain.
The camera is on a long 600 frame animation away from the island. At frame 518 the cloud on over the horizon err, disappears.
The camera is 3740.29m high, the cloud is 3985 high and 500 depth. This means that the cloud base is at 3735m, very close to the camera height.

Is there a correlation between camera height and cloud base?

Can it be resolved?

Spent some time on this trying to figure it out....to no avail unfortunately :(
The other way around it works properly. That is: putting a camera just below the upper cloud boundary and have it face upwards. Then all the clouds render.
Guess it's some kind of clipping plane issue which is being dealt with internally. Or an over-active optimalization which considers those clouds shouldn't be rendered because they're likely to be occluded. Not sure. Guess it's worth a bug-report.

Thanks Martin.
Well since the deadline is NOW (AAARRRGGGHHH !!!!) we have decided its a nice sunny day with no clouds!
LOL
I'm fairly sure I have seen this mentioned before but can't find where. As you suggested I have escalated it to a bug report over at the other place.
Cheers and thanks for looking into it.

can't find the problem solution for that.
very strange issue

Strange indeed. The scene takes longer than I'd expect to render in general, too. Hopefully we can track it down in development.
