Cinema screensaver/sleep mode bug.

[noseman]

it's not a bug.
Go to C4D's Preferences - System pane - Uncheck "Deny Power Cycle"
If that's on, C4D doesn't allow the system to go to sleep or into screensaver mode.

Hope that helps!

I think that if you are rendering, you don't want the system to go to sleep, or else the render will stop/pause until you wake the computer up! This is why there's the anti-sleep preference.

I have simply gotten in the habit of turning my monitors off when I will be away for more than an hour or so. That way C4D can continue rendering, I don't get screen burn-in AND, I save a few watts of electricity!

That's all!?
Damn, I thought I remembered someone saying something about how it was a known issue that apple knew about but hasn't fixed yet.

Thanks man.
I feel pretty stupid about now...

I have simply gotten in the habit of turning my monitors off when I will be away for more than an hour or so. That way C4D can continue rendering, I don't get screen burn-in AND, I save a few watts of electricity! Yeah that's what I do too. If I'm rendering.
Sometimes though, if I'm working on a scene and have to do something like take the dog out, I forget to turn the monitor off and it won't go into screensaver.
If it takes a little longer than normal then the screen is just sitting there.
I had an incident a few months ago where something went wrong with the screen.
It had a major case of image burn. Every other pixel was darkened, and if I closed or minimized a window it took a good 10 minutes for the image to fade away.
It was very much unusable in that state.
I always pay the extra for the extended warranty when I buy a system. So Apple sent me a box and I shipped the display back, they replaced the LCD module and I had it back in a couple days.
I'm not sure if cinema played a big role in that, but I don't want to have to send the display back again if I don't have to.

you are not going mad and it is a bug currently in cinema R10+.

deny power cycle doesn't work in R10 as it should.

in R9 you could set up cinema so that when rendering the screen would power down (or the screen saver kick in) to save the screen and when the render had finished the system would go to sleep (to save power).

in R10 none of this happens. cinema stops the system from doing anything when it is open.

very bad. i have to manually dim the screen when i know i am going to be rendering overnight and who knows what is happening to my unspun down hard drive.

reported to maxon but apparently this is a problem with apple (quite why R9 works and R10 doesn't when the OS is unchanged is just one of those things).

cheers, simon w.

p.s. deny power cycle actually refers to the ability for cinema to stop the mac from sleeping prematurely - with it off the os controls when the machine gets powered down so in theory your mac could completely go to sleep in the middle of a render. with deny power cycle active then the theory is that cinema now tells the OS when it is safe to sleep the screen and the computer. this worked fine in R9 but not in R10.

I thought so!
Someone made mention of this in a post regarding Cinema10.5, and how it's Apples problem and they aren't doing a thing to fix it.
They'll probably fix it in Leopard, but totally disregard it in Tiger. So if you want it fixed, the answer is simple-Upgrade.

Screw it! If my display goes down again, it's still covered in the Apple protection plan so they can pay for me to ship it, then fix it again.

The odd part is that when it happened last time, they replaced the LCD module.
On the invoice, it says they replaced the Sony LCD module with an LG module.
I don't know if one is inferior to the other though.
I know the cinema displays are based on Sony widescreen LCD's, and I've heard LG's are good also.
It doesn't look any better or any worse as far as I can tell.

It's just a bit unsettling to know that if I don't shut my display down it could cause damage, and that they know it, but don't give a damn.

We should get a petition going, and confront apple with it.
Because I have no plans to upgrade to Leopard until they get the problems with it ironed out.

Currently the main problem behind this is a bug in OS X. Once Apple fixes it the problem should vanish, if that fix needs any adjustment to CINEMA 4D it will be made by MAXON.

Just turn off your display and it'll be fine. I'm using an Apple 23'' display (the aluminum ones), and in System Preferences I have it set so that when I hit the power button on the display it turns the display off (but my computer stays on). Works fine for me.

You can't do that on an imac, and as for having a screen saver running that takes up cycle time, not good on a big render..

I managed to find a little program that allows you to dim the screen (all the way). Just like on my mac book. Why apple don't supply this is beyond me, very irritating and unproffesional.

With a mac book when you close the lid the machine alway sleeps and there is no setting to change it!? When i contacted apple they pointed me to a third party plugin i would have to buy!! As well thought out as a game of chess on a roller coaster..
