Render Faster With Mac

50 posts in this topic

Hello I have a macbook pro with the latest Core i7 and 16GB ram plus over 400GB harddrive and a graphics card.

What the problem is with extra scenes putting into 1 file like adding more grass environments that has 1000000s of hairs and 85658 guides so that you can't see the botton plane texture.

Well on a separate file when I try and change the guides up it crashes by loading and not responding for an hour so I'm wondering is it because the 64bit R12 isn't using enough GB ram or is it because of something else that I don't know of as it's the only application open?

On preferences my memory options is 9999999. And shadows,reflection and shadow depth is off. Any ideas would be appreciated :-)

"On preferences my memory options is 9,999,999."

What exactly does this mean? That's how much memory you allocated to what? The numbers on that pref pane are in MB, so it may be that you are telling Cinema to use 10,000 GB of RAM. Gigabytes. Maybe C4D is using ALL the RAM in your system which means the OS has no resources to function. The OS or C4D is probably resorting to using the HD as virtual RAM which is very slow. Just a thought.

Not to mention that a laptop is not a great choice for a complex 3D project like that.

Does not any modern OS automatically allocate resources as required up to the the limit of what's available?

I know Activity monitor can show how much memory it uses each time and yes my memory in preferences is 99999999 even on Harddrive MB I put it up to 99999999? could there be a solution to this or anything else to improve render space like do I need a better graphics card or more GB ram? more help would be appreciated :-)

I'm not sure what memory setting in the prefs you set to such high values, the only one that has any impact on renderspeed is the Displacement setting and that only if you use SPD. In general you can leave it set to defaults.

85000 Guides sound like way more than you might actualy need. I rarely fsee a situation where more than a couple of hundred or a very few thousand are needed.

My guess is that your scene isn't set up optimaly, thus using much more memory than is neccesary.

@Srek here is the settings I'm talking about as I've tooken a screenshot of the memory settings.

And yes I tend to use alot of guides just to fill the plane up really so that the plane texture cannot be seen but only the grass like in real life.

That's a complete misuse of the guides. Just because you have 85000 guides doesn't mean you get 85000 hairs. You get the number of hairs specified in the Hairs tab of the hair object. You could have 1 guide and you'd still get that many hairs (try it and see).

I wonder if your graphics card is having trouble handling a scene with that many guides. It's a laptop so I would guess (not knowing much about Mac hardware) that its graphics card is not the most powerful. Anyway, if upping the number of guides hangs the machine... keep the number of guides low.

It might be worthwhile contemplating the advice in the Help about that memory setting. It reads "Make sure this value is not set too high as to impare other applications running parallel to CINEMA 4D."

I've just tested it with the 1 file background of 1 guide only and yes the hairs still appear but it still took about 18min to render I know on hairs is about 6000000 and 8 segments fill hairs has 5000000. And as mentioned on 1 of my past posts it's to make sure I only see the grass on the plane but not the underneath texture.

Also here is the info on my mac if anything could be updated to improve the render space. As wouldn't it be lovely to have all 3D environments into 1 file like a 3D island with few towns and countrysides all nicely welded together.

Any more help would be appreciated.

The only ideas I've come up with is these wait for a new faster processor better then core i7 and talk to MAXON themselves to see if there is anything new to speed up renderings for C4D. As I mentioned it would be lovely to see a file with all backgrounds added and I can save up for it if it was expensive.

Thanks for your ideas though.

Could you post a render of what it looks like with around 1/100 the number of hairs you have right now?

There's always ways to cheat when it comes to rendering scenes. I just can't imagine that you can't sacrifice anything on your file...
