not enough memory issue

[John Meilak]

Chuks, when you said earlier you copied and pasted objects were they polygonal objects or were you referring to the cloners? These all show benefit with render instances, so if were copying and pasting objects, try using duplicate as render instances as well.

Failing that, I don’t think you have enough RAM – check your task manager and the swap file size- the hard drive is used to extend RAM, but that can be limited by your available hard disk space- if not enough free space, it will be out.

Ok let me see how best I can explain it, am trying to build a 3phase gravitational separator, it has manual ball valves flange, liquid level control valves, pipes e.t.c. Most of the above mentioned I used loft nubs,sweep nubs, and extrude commands to achieve. Then there are a lot of bolts and knots holding pieces together, using the cloner object i was able to distribute bolts and knots around a flange. Let me give a clear example of what I meant by “copy and paste objects”, if after creating a ball valve ( basically comprises of bolts in a cloner objects, Boole for creating a cylindrical hole in a ball,loft nub for creating the valve body) I will then copy and paste the one I have created in other parts of the separator that needs a ball valve. And this separator is made up of many valves and pipes for fluid flow manipulations. By copying and pasting to have a duplicate I end up adding more cloner objects to the scene (initially without render instance turned on) hence consuming more unnecessary memory space, well even with that render instance checked and the memory reduced, I still can’t get the memory issue solved.with c4d workspace currently running without my project, the task manager indicates a memory usage of 126.7mb and a total of 17% of the RAM (12gb) used. When the separator project is turned the memory usage shoots up to and average of 1621.6mb and a total of 29% of the ram usage, mind u the c4d constitutes 33% of the used up memory too. If I hit render sometimes it goes up to 2342.15mb, my processor speed is 2.2ghz, I have a 2gb amd radeon graphic card inbuilt.I really hope I am making sense with all wat am saying. Am trying to upload it to one of this cloud services so u guys can check on it as well, unfortunately for me here in Nigeria the Internet services can be shaky sometimes but I will get it on air soonest. I really appreciate the concern of you guys and am very optimistic that the problem will be solved here.
Thanks

Hi Chuks looks complicated.
I just re-read your post on May 8, are you rendering an animation? I thought a still? In that case, if you weren’t getting an out of memory error then with whatever you were doing (I didn’t follow), the long preparation you were getting may be due to you using Full Animation mode where preparation is done for all frames. Do the objects move? If not, try turning that off to use camera animation, to prepares and renders frame by frame. (I’d turn it off anyway just to test).

[Ekpeti Chuks]

I want to do an animation video to show the internal mechanism of the project, I have finish the scene with different camera views and a stage to organise the camera views. I was advice to render as image sequence in png then export to after effect to make a video of it. At the moment if I click on the render view it renders (after making sure all cloner render instances are turned on), but if I click on render picture viewer it takes a long time calculating and at the end it displays not enough memory, even when the render settings is set to current key frame.

[John Meilak]

OK also what resolution are you rendering at, try the lowest quality to see if that helps. Try rendering a still not an animation to test a frame as it’s a lot smaller. Don’t forget not only do you have the OS, C4D, your big file, other apps in RAM, it has to have space to calculate, and then produce the final output as per your render settings in RAM also, and when you click render it calculates if it enough resources to do it. Again, it is a RAM question, and let’s be honest, your computer may be underpowered.

[Ekpeti Chuks]

I tried rendering at a lower pixel and rendering just a frame as well and it’s still taking too much time calculating the rendering and at the end it displays not enough memory after 28mins. While it’s calculating the rendering I checked my task bar and it showed the following cpu-31% (with c4d 30.9%), memory 34% (with c4d 2088.4mb). So even at rendering it still doesn’t go up to half of to total ram size, which to me is a bit fair on the memory side. When I click play on my time it drags a lot and starts displaying in wire frames. when I click on the play button on the timeline, my task bar displays an average of the following cpu 34% (c4d 32.6%) memory 26% (c4d 1019.4mb) but the timeline drags it doesn’t run as fast as it does in my smaller projects. I tried rendering again and as it’s calculating I found out that the cpu rises up to 60% and and when it gets above 60% it displays not responding in the c4d task bar status then it’s comes down to 56% and c4d comes on again,it keeps fluctuating witin the range of 54-62 with c4d displaying not responding in the task bar above 60%, while the memory goes up to 35% with c4d 2145.6mb

I’d expect the real hit to memory will come when it is writing the frames, it seems you are in the calculation evaluation phase, and maybe it decided against. But then it is surprising it’s the same for a still render. What I was really getting at before was what are your render settings, are you trying to render HD, large format etc, do have large textures. All I can suggest is try doing a hardware render (preview render, low quality but renders quickly as a movie– poss avi), or try rendering at a small resolution, maybe even 640×480, to find your limit. It may also be possible to optimise your file further- Beyond that I can’t suggest anything as I haven’t a clear idea of what is in your file,

Well I tried rendering the same project on another system with almost the same spec, and I found out it was displaying the same result, obviously the problem is not from my computer, I guess the project rendering is too big for my system to handle. I tried breaking it into smaller units and rendering it in png sequence hoping to superimpose them in aftereffects, but even at smaller units it’s renders only some few frames and display d not enough memory at the end. I have played around with the render settings ( using hardware rending as well), it only renders some few frame and displays the not enough memory at the end. I even try to render fewer frames (1-40) yet it displays not enough memory. Am thinking of looking for someone with a more powerful machine to help me render it (maybe a work station), but before i that please I want to know if there are render plugins that can help my computer accomplish this task even if it will take a very long time to render I will be patient enough for that, I just want to get rid of this not enough memory issue. I was reading about cineman renderer, and I found this very interesting “The Physical Renderer in Cinema 4D R15 uses Intel’s Embraer raytracing engine whose highly optimized algorithms increase render power by up to 300% – without any reduction in image quality! The more complex a scene is, the more you get out of this increased power, regardless of which processor you’re using!”….please I wanna know if the above stated (as copied from the info source) means I have a better shot on rendering the project using r15 on my computer. Thank once again for all your comments

[John Meilak]

Hi Chuks Why don’t you download the demo version of R17, I don’t think not much changed to renderer since R15 (I think reflectance but don’t worry about that). You cant save but will answer that question for you.
If you got it to render some frames by cutting down, check your task manager while its happening to see total RAM available and virtual RAM – make sure you have enough free disk space for virtual RAM as that would be limiting for R17 also..

[Ekpeti Chuks]

I use r14, I think I will get the r17. After cutting down and rendering it displays the not enough memory when the total ram usage is just 30%.
