Render stops midway

Post by smriti »

Hi,
Is anyone having the problem of their render stopping midway before its finished?
I need to keep updating my rendering for it to keep going and even then the final product is not coming out in a high resolution quality (with a lot of dots).
Does anyone have answers to this?

Hi,

Can you tell me the following...

1. version you are using.
2. CPU only, GPU only, or both?
3. Are you using Ray trace, path trace or photon trace?
4. What kind of system you have? Like, Intel i7, 4 cores, 8GB RAM.
5. How long does it take before it stop.
6. Does this happen on any model you try to render.

1. version you are using - 3.02
2. CPU only, GPU only, or both? - both
3. Are you using Ray trace, path trace or photon trace? - tried all 3
4. What kind of system you have? Like, Intel i7, 4 cores, 8GB RAM - intel core i5
5. How long does it take before it stop - less than 5mins
6. Does this happen on any model you try to render - Yes
There is alot of noise on the model

Depending on the complexity of your model, and how much light it gets, the dots may take longer to go away. What do you use to light up your model? The sun and sky? or artificial lights? Also, after 5 min. how many passes or samples did it do? When you start the render, does the GPU setting in the Path tracing is unchecked? What kind of video card do you have? Sorry for all the questions, but I need to know so I can better diagnose the problem! The more info I have, the better, even a screen shot would help.

I'm working on an interior space so tried with just artificial light and artificial light with sun.
Passes varies, I just did 2 different renderings - I went up to 23 and the other till 40.
Yes the CPU acceleration unchecks automatically.

Thanks for the info.

If you have the sun enabled, you should also enable the sky, but that is not the problem. Also, if you use artificial lights, you should use fast shadows or true shadows. Ambient occlusion is basically if you have no lights at all. But is up to you.

I suspect the problem is with the glasses (windows), some kind of loop is occurring, and errors out eventually.

Can you PM (private message) me the ROF file along with the texture folder (put them all in a zip file)? I do not need the SKP file. Then I can try it here just as you do and know exactly what the problem is, and have a solution.

I got your PM thanks. The PM notification to your email bounced, so I'm letting you know here that I got it and I'm checking it out now. Give me 10 min or so...

ok, it did not stop on me as it did on yours. But there are a few things wrong...

1. Your glasses (windows) are a single face, not thick as when you push/pull, and you selected the material as "Glass". I changed it to "Glass (thin)" instead because it is not thick (push/pull to make it solid).

2. The sun did not shine in because it is below the horizon. See sun setting, Elevation is set to minus. I changed it to 21 and also changed the Azimuth to 193 (see second screen shot).

Beside that, your model looks very nice and well made. But, there is also an "X-Ray Level" setting you can use. I suggest you close the wall were the camera is, to see inside, so if that one is one layer, then set the X-Ray Level to 1, if it's a thick wall, 2 layers, set it to 2 and you'll be able to render it and see inside while preserving the wall reflection on the windows as appose to a black empty space. I couldn't do it since I do not have the SKP file.

Another thing, your GPU setting is not ON, so perhaps you need to install the latest NVidia driver which should also install the latest OpenCL which Raylectron uses.

Here is a render in progress with the artificial lights only. But I changed the light setting to be, power=35 and angle=90...

Here is another render with the sun/sky only, default settings, only changed the sun position...

Can you try my suggestions see if this will fix the problem?

Re: Render stops (not even) midway

i have the same, or a quite similar, problem.

prior to upgrading a rendering would run and run and run. and look gorgeous.

after upgrading, with exactly the same model, it will stop, randomly, and quite incomplete. this makes the software rather useless. if you tell me the materials are incorrect or the glass isn't thick or whatnot i'll listen, but this seems to be a new issue.

that said, i'm quite excited to play with the animation feature (smile)...

also, the prior version didn't totally consume system resources like this one seems to do. working in any other program seems compromised.

hoping these are simply bugs that can be worked out.

thanks.

ok, which version are you using now with the problem, and which version before didn't have the problem?

If you can give me as much info as possible, that would help. Are you using Path tracing? How much memory did and now use for the same model etc.

1. version you are using. 3.0.6.0 (downloaded fresh this morning)
2. CPU only, GPU only, or both? gpu acceleration
3. Are you using Ray trace, path trace or photon trace? path trace with sun, sky, and artificial lights
4. What kind of system you have? Like, Intel i7, 4 cores, 8GB RAM. acpi x64 / intel i7 8 core / ati firepro v4800
5. How long does it take before it stop. seems to be less than 10 minutes
6. Does this happen on any model you try to render. so far yes. only tried on two different models...

i don't recall the prior version, 2.x something.

Thanks for the info. But is it possible for you to PM me a test model, not the SKP file, but the ROF file along with the texture folder of it, and the CFG file, you can make the CFG by doing a "Save model settings"? Because none of our models have ever done this to us, and v3.06 has been running for 3 days now and that's why we released it yesterday!

ok I got the model thanks and I'm running some test right now. I'll keep you posted as soon as I find something. Outstanding design by the way!

It's been rendering for 25 minutes now and still going.

While it renders on yours, are you doing anything else with the computer?
Are you using render slaves?
Do you have "Auto update view" turned ON?
Is your screen saver kicks in while rendering?

nothing else much (outlook, web browser) is up and running.

ironically, i guess, i've also had it continue to run now. it's been going for 50+ minutes during a lunch meeting. i did install the latest upgrade this morning, so maybe that's what was giving it fits? thanks!

Mine is at 60 minutes now and still going.

If you use to use v2 and you are loading the ROF from v2 into v3, maybe that's what did it. In this case, I would suggest to load your model in Sketchup and re-export it so that it's v3 exported as oppose to v2.

Can you please let me know if it happen again?
