Maxwell Render | Official public forum

Hi

I have problem rendering high resolution night renderings.
3000x2000 px renders without problem, but when rendering 4000x3000 it crash.
I have quad xeon with 8gb of ram.
Any suggestion what to do ?
Thanks

Does it crash before starting to render? I assume you already use 64 bit version of Maxwell, right?

What a rapid reply Tom !!!

I use 64 bit with Max
it crash before rendering

I remember that in Maxwell version 1.23 or something ...very old was option HD and it use to help in such situations

OK, the problem seems different. Could you try and see if it still crashes using override material?

ok...testing I need few minutes...



still the same problem

It crashes when the render is bigger than 3000x2200, even if I chose to override material

Could you compress and send me the MXS file? No textures please.

Can I have Your e-mail pleas?

Hi Tom,

I have a similar problem at a certain high resolution. In my case it starts rendering, it writes the mxi file and then immediatly crashes.

I´m working with 32-bit Windows XP.

I also had the problem with another project. But there it crashed when I kept the resolution, but tried to render some trees.

As the problem is a bit different, I´ll also send you the scene.

32 bit - probably a RAM issue.

Maxwell uses 1 of the 3 GB RAM while rendering, I guess that´s not the problem.

Ok I did render smal resolution

Tom, I send you the scene.



Heres is the final image...with little PS

Thanks Michal, the problem was memory even though you're using 64 bit version because Color ML memory consumption is 8 times more than Intensity ML. So, your hires scene with 5 emitter in Color ML requires 6.4 GB of plain memory only for MXI storage excluding textures and geometry.

Yes, your scene asks for 5000 x 3750 and Windows cannot supply Maxwell 32 with such continuous space most of the time. You can either decrese the resolution (for example 4000 renders here) or switch to 64 bit Maxwell and there won't be crashes.

Thanks Tom!!!
That explains a lot, hehe but I thought that 8 GB o ram is much…I will consider changing for 16GB
