Topic: Crash when rendering

[Guillermor]

Hi, I stumbled across lumion and noticed how simple everything flows, we are considering buying it for our company, i downloaded the trial demo, had a little trouble but in the forums found all the answers I needed, I changed the nvidia control panel settings so that my computer used the correct graphics card, i also downloaded the most recent software from the Nvidia page, everything runs smoothly even on 4 stars quality, the only problem is whenever I try to render the image the application crashes.

Im running Lumion 3.2.1

Asus N series
Graphics card is an Nvidia Geforce 750m
8GB ram

Hi Guillermor

Thanks for your interest in Lumion. 

The Nvidia Geforce 750m has a Passmark of 1491, so its is only just reaching minimum guidelines for a GPU for Lumion.  Individually, the card or the power supply may not be strong enough to perform the renders.

The scene you tried rendering does not look very demanding, so that lends weight that it's the GPU itself. 
Can you test render an image from the Artistic Effects Example, and if that does not work, then open the New Empty scene, try Island, then Sunny Day and render a Photo.

Also, what was the resolution?

It looks like you have installed the latest GPU drivers, which normally would be fine.  In this case can I get you to install the earlier drivers 337.88.

I cant get it to work, it seems odd that i can view the editor in high resolution and quality but when I try to render it crashes.

I tryied the artist effects, the island and the sunny day... everything crashed

I also downgraded the Nvidia Software but same error.

I ran the OCCT tests as someone sugested in another post this is the message i got, do you know what it could mean?

Hi

Editor resolution and rendering place two different demands on the GPU.

We would need to see the GPU: 3D tab results.

Alternatively run: GPU-Z and attach a screencapture.  This only reports the features of the card. 

To stress test try FurMark.

This is what i got with the 3d tab and gpu-z

Hi Peterm. My Nod32 scan told me the Furmark is not safe! ?

[peterm]

Hi Serget704

To the best of my knowledge Furmark is fine.  The compression or 3D code they use for super optimized 3D routines has a similar footstamp as some crack and virus software, so NOD32 thinks it's the later. 

Just downloaded it and Windows Defender does not have a problem with it.

[Guillermor]

When I ran the Furmark it started to heat up more than the recommended so i quitted the application, i didn't want to mess it up, i also posted the screenshots above

Thanks!

Hi Guillermor

Fair enough, we don't want you to burn out the GPU. 

If it quickly reached temperature limits, then that also sounds like the card just does not have the performance to run well.  Lumion requires a lot of GPU resources to get the best out of it.

I see in the OCCT GPU Tab that the Intel 4600 is selected.  Can you run the test with the NVIDIA card selected?

Can you double-check the NVIDIA Control Panel settings to make sure the NVIDIA card is set for use with Lumion.

As a last test I would run PassMark PC Performance tool for a comprehensive test and report of the laptop.  You can also get a GPU performance that can be compared to their online submitted scores.

Unless there are some other reasons to think the hardware might work, I would suggest that you need to see if you can use Lumion on a suitable desktop PC or high-end (GTX770M, 780M 970M, 980M) laptop, that more closely matches our recommended requirements.

They say sometimes the problem is right before our noses, in this case i didnt know it. Turns out what was causing the crashes was GOOGLE CHROME, after searching everywhere for the problem, turns out chrome causes something en the graphics card that overuses it so when I tried to render an image it was too much. I post the solution so you can help others with my problem because it's something really simple, now i can't use chrome in my computer because it even runs in the background, but hey... i installed mozilla and I can use Lumion which is a big win for me.

Cheers from México!

Hi Guillermor

Thanks for the update, and how you resolved the problem.  Great research  .

Certainly never heard of that.  We have many (including myself) that use Chrome without issue.  Perhaps it relates more to the added/overuse load on the card with Lumion and Chrome operating at same time.

I am aware that there is a switch in (most) browsers these days that lets the browser render using the GPU rather than a software render, because it's so much faster.

Can you provide a link to information on that Google Chrome issue please.

All the best with the Lumion free version testing.  Hopefully your company will be able to look at purchasing Lumion.
