Lumion may occasionally run out of Graphics Card Memory and System Memory when working on complex projects (for example when importing a very large model). If that happens, it will start to use Virtual Memory. This memory type relies on allocating some free space on the hard disk for virtual storage when the above memory is all used. Lumion recommends at least 50GB and up to 150GB for more complicated projects.
Note: The Virtual Memory will take up the amount of space in the selected drive. Therefore, make sure that there is sufficient free space for the increase. If you selected the drive where your Documents folder is located (usually C), verify that you have more than 30GB of free space after you have made the change. That is necessary for Lumion to work properly.
If Lumion urges you to increase the amount of Virtual Memory, please follow the guidelined steps below.
Step 1: Click on the Windows Start button, type the word “performance” on the search bar and select “Adjust the appearance and performance of Windows”.

Step 2: In the “Performance Options” window, go to the “Advanced” tab and click on “Change” under Virtual Memory.

Step 3: Select a drive with enough free space, click on “Custom size” and enter the value Lumion suggested in both the “Initial size” and the “Maximum size” fields.

Step 4: Uncheck the “Automatically manage paging file size for all drives” option, then click on “Set”, then “OK”, and restart the PC. In case you need help freeing up space for this procedure, follow the Microsoft website HERE.
If increasing the amount of Virtual Memory on your computer is not feasible and only temporary and you have many large projects and you need to use your computer for other needs, iRender will be a radical alternative.

Topic: Lumion out of memory (Read 16599 times)
May 20, 2011, 11:12:47 am
I’ve had crashes on two big projects, pop up said «Lumion went out of memory»
Is that the memory of the computer or the memory of the graphics card?
The project I’m working on now has a lot of «heavy» hedges in it. Imported 3ds file.
Also what can I do to work around this problem. Work in Low mem mode? and then when it is time to export the images (I»m working on stills now) switch to normal mode? Or does the low mem mode generates the same pictures as the normal mode, so there’s no need to switch before generating the pictures?
I did move the hedges to a seperate layer, that speed things up in the viewport.
other tips?
sytem specs:Intel Q9300, 3GB Ram, WinXP Pro, Nvidia GTX460 1GB

total size of folder with textures of main model is 4,5Mb, largest textures are 600kb.
Don’t think that’s the problem.
May 20, 2011, 12:06:23 pm
No need to switch.
Your scene is too heavy and it’s a safe bet those nice hedges play a big part in this.
Lumion can perform small miracles but we’ll have to wait a bit before it actually allows you to increase your
physical memory 
Can’t you optimize the hedge models? I saw lots and lots of branches in them and perhaps you can just make 2 versions, 1 low poly and 1 high poly for very close to the cam.

600kb jpg… maybe reconsider to scale it down, if you have like 10 of these, it can be a killer in performance.

The smart thing to do is what Aaron says I think, optimize the hedge model.
I can reproduce the error now. Lumion crashes when I try to edit/assign a material from the main model.
If I don’t edit the material all is fine, a bit slow, but it works.
I can even add some more hedges

Just use teh 64bit version. I had the same issues lately and after switching to 64bit all was fine.
May 24, 2011, 10:50:40 am
Also you can use the 32 bit version but make sure you use a 64 bit OS for a bit more memory.

graphics card is the key of out of memory!My graphics card is 4G DDR3.That will be OK!
October 06, 2011, 10:20:47 am
I don’t think it’s entirely graphics card related.
My situation:
work pc: Winxp, 3Gb, GTX460 1Gb
home pc: Win7-64, 4Gb(upgraded to 12Gb), GTX460 1Gb
Same scene gives «out of memory» errors on work pc, on home pc all is fine.
I have a hunch that it is related to the size/memory of seperate imported models(fbx, dae). With smaller models the work pc is fine, but when working with larger ones sometimes the out of memory error pops up.

Running Windows XP (32-bit?) with 3Gb ram is what’s preventing you from working with more complex scenes on your work PC.
The 32-bit version of Windows only lets Lumion (and other applications) use a maximum of 3.5gb of the system memory. More complex projects will require more memory and preferably a 64-bit version of Windows.
Try running Task Manager to monitor the memory consumption of Lumion while you’re working on that project (use the latest version, ie, SP2 Build 8 while you do this).
As an example, I’ve got Windows 7 64-bit with 6Gb ram, and with just Firefox, Skype and MSN Windows is using 2.35Gb. And I haven’t even started Lumion yet.
So if you only have 3Gb ram, there’s not much left for Lumion to play with.

What does it mean when Lumion runs out of memory?
One reason for Lumion to crash is that it may sometimes run out of Graphics Card Memory and System Memory. If that happens, Virtual Memory will be used. This memory type relies on free space on the hard disk. You can follow this link to increase the Virtual Memory.
How do I increase memory for Lumion 10?
2.1: Windows 10:
- Click on the link below.
- Webpage link: Tips to improve PC performance in Windows 10.
- Click on 3. Check memory and memory usage and follow the instructions in the paragraph called Change the paging file size to improve performance.
- Restart the PC.
How can I improve my Lumion performance?
Make the Lumion window smaller and/or reduce the resolution of your monitor (the fewer pixels it needs to render, the higher the framerate is). Or, set the Editor Resolution to a lower percentage than 100% on the Settings screen. Set the Editor Quality to a lower star quality on the Settings screen.
How do I restore a Lumion file?
1. Back-ups in Lumion 9.0 and newer
- In Lumion, using SaveAs to make a separate copy of the LS Project file as a version copy.
- Use back-up or file sync software.
- Windows File History and/or.
- An online cloud back-up service (so long as it does not backup at the same time as you are trying to save files).
How do I increase Virtual Memory?
Increasing Virtual Memory in Windows 10
- Go to the Start Menu and click on Settings.
- Type performance.
- Choose Adjust the appearance and performance of Windows.
- In the new window, go to the Advanced tab and under the Virtual memory section, click on Change.
What files can Lumion open?
The supported model file formats are as follows:
- DAE (Collada)
- SKP (SketchUp)
- FBX.
- DWG.
- DXF.
- 3DS.
- OBJ.
- MAX (Requires a 3ds Max installation)
How do I import a heavy SketchUp file into Lumion?
2. The best import method for your version of SketchUp and Lumion
- Lumion 11.0.1 or newer: LiveSync or import .SKP file.
- Lumion 11.0: LiveSync or import .SKP file (File -> Save as -> SketchUp 2020 format)
- Lumion 10.3 – 10.5: LiveSync or import .SKP file (File -> Save as -> SketchUp 2020 format)
Is 8gb RAM enough for Lumion?
Additionally, faster hardware allows for a faster rendering time in Lumion.
…
Find out if your desktop PC or laptop is fast enough.
| Recommended requirements | |
|---|---|
| System memory (RAM) | 32 GB or more |
| Graphics card memory (VRAM) | 8 GB or more |
How much RAM does Lumion need?
Does Lumion work on your current computer? Lumion requires a PC with a fast NVIDIA or AMD graphics card with at least 2GB memory. If your laptop PC has a slow graphics card with less memory, or, if it only has an Intel HD graphics card, then your laptop PC is unsuitable for Lumion.
How do you purge a Lumion file?
1.1: You can remove files for the Imported Models via the Lumion Imported Model interface by clicking on the Delete model button (Bin icon). 1.2: Note that the model you remove cannot be present in the Project you currently have open.
Why is Lumion so slow?
Some SketchUp models that have curved surfaces, such as a sphere or bottle, might use a so-called projected texture mapping method which is not supported in other applications. The result is that the model will become very slow to display and render in Lumion 8.0 (and older versions).
1. What is Virtual Memory?
When working on complex scenes in Lumion, it may sometimes run out of graphics card memory and system memory (for example when importing a very large model).
If that happens, it will start to use Virtual Memory. This memory type relies on free space on the harddisk.
Please follow the instructions below if we ask you to increase the amount of Virtual Memory.
We recommend at least 50GB, and for very complex Scenes up to 100 to 150GB.
2. Here’s how to increase the amount of Virtual Memory:
2.1: Windows 10:
- Click on the link below.
- Webpage link: Tips to improve PC performance in Windows 10
- Click on 3. Check memory and memory usage and follow the instructions in the paragraph called Change the paging file size to improve performance.
- Restart the PC.
2.2: Windows 7:
- Click on the link below and follow the instructions at the bottom of the page.
- Webpage link: Optimize Windows for better performance
- Restart the PC.

Здравия ДТФ, произошла проблема при которой вылетают игры Borderlands 3 и PUBG с ошибками run out of memory, компьютер Ryzen 7 1700 GTX 660 2gb 16gb ddr4 2400, с недавних пор эта проблема проявляется в этих играх (в других не проверял) буквально через 1.5 часа что крайне раздражает и не позволяет нормально играть, файл подкачки до этого убавлял до 2 гигов ибо изначально автоматом ставило почти 30ГБ файла. После изменения файла игралось все стабильно и по гиганстким сессиям.
