Hi,

I have a scene that renders fine as a lowres when testing, but as soon as I change my settings for the final output to 30x40 cm 300dpi MXCL crashes after voxelization. If I change the DPI to 200-220 (getting a lower resolution) the render starts as it should.

I am using Maxwell with Cinema 4D, but I have tried to render the MXS-scene from MX Studio with the same crashes when going highres.

Anyone who knows how to solve this?

Thanks in advance!

Sounds like a memory problem! Check to see what the ram usage is just to make sure!

OK... I've got a MacPro with 8gb ram, shouldn't this be enough? The scene isn't that heavy either (very few textures and low polycount). Where can I see the memory usage for a render?

Thanks for your help.

Should be enough, when you're able to use the 8gb...

But when you're running a 32bit windows system on your macpro, you'll still have your usable memory at around 3gb.
Looks different when you're on 64bit windows.. or you're running a macOS... that's 64bit by default... IF you're running a whatsoever 64bit system, you gotto be sure that you're running the 64 bit mxcl... that one is 'kind of' experimental or 'pre'-final or something... at least for a macOS, if I remember correctly. you will have luck, when you use the search functionality that this forum provides.

Then: if you're asking for the memory that is actually used by a specific task then it's the 'Task Manager' on a windows system, that gives you that information... on a macOS it ought ot be called somthing like activity service or so... I only used it in german, sorry... there it was called 'aktivitätsanzeige'... it does the same thing as that windows-service...

But: if you're question was meant differently, I can suggest to have a forum search for a tool, that was created by one of those extremely talented guys, hanging around those forum corners... he calls himself 'kabe', the tool that he wrote is called 'mxcalculator' (or similar). It calculates the usage of memory for a mx rendering with given parameters like size (in pixel*pixel), count of multilights and so on....

by the way... are you using the mulitlight option in your render? try shutting it off, after you adjusted the lights correctly... and see what happens...

sorry for the lengthy post...

good luck.

Thanks! I am running Mac OS X 10.5.6. I will try and turn off MultiLight and see if that helps, otherwise I will have a search for the 64-bit Mac info and see if that is the solution.

maxwell really should check if there is enough memory and give a better feedback ... not just crash with an inconclusive error

the tool mashium meant is called mxc and can be found here: http://www.klausbusse.de/mxc/
it is very useful!

Thanks Kami,
Have downloaded MXC now and will try it ASAP.

Once I could not install a 64bit OS and I ran the whole Maxwell render from a Ubuntu Live cd. Crazy but it worked perfectly.
So crazy that the day after I also create a temporary network from 4 workstation, normally running Windows 32, temporarily running Linux 64.

Huge ram come here.
