Rendering issues...please help

Okay, I am new to Lumion, and I am getting frustrated with this forum, so please excuse if this is in the wrong location.

I have been working with Lumion for about a week and my boss is having me re-render some images for a client.  They are wanting several views. I set everything up, but when I go to render only one of the images actually rendered (see attached, 'asu1').  All of the other images (see attached 'asu1') go through the rendering process and come out black!

What gives?  I tried to render all 6 scenes and only the 3rd one came out correctly.  All of the settings are the same and I tried different rendering qualities and only the 'desktop' size would render correctly, but only for the 3rd image. 

This is a rather large file, but why would only one come out correctly?  Please help.  Thanks.

Hi johnnyboy

No problem, its a reasonably large forum, although probably at the moment you only see the non-commercial (guest) forum topics.

I have moved your post to the appropriate Board.

Nice detailed looking scene.

How big is the scene re number of 3D Points?

Also, to help in trying to identify some possible causes of the problem can you please:
1. list what version of Lumion your are using.

2. specify your PC specs (graphics card specs, CPU, RAM, PC model, Windows version, laptop or workstation).

3. Attach the dxdiag_Lumion.txt report if running V3.1+ (Files --> click on System Speed bar chart --> click on button Run DXDiag) or Windows Start --> run DXDiag.exe for the DirectX report of your system.

Thanks.

Thanks for the reply.  Here are the answers:

Scene 3D Points:  43.5 million
Version:  Lumion Pro 3.2.1
PC Specs:
Graphic Card: NVIDIA GeForce GTX 560M
I am running this on an ASUS laptop with Windows 7, intel Core i7 processor, and 1TB of RAM. 

I have done several renderings of other projects, and this is (hopefully) the only one with this problem. 

I ran this again this morning to see if turning off and restarting my computer would help and it did not, the issue is still there.

Hi johnnyboy, the 560M graphics card only has 1,540 PassMark points. That's just 40 points more than is required for 'simple scenes' in Lumion, so you're really pushing it to the limit, and I'm not surprised that it isn't working in this particular scene.

The thing is... 43.5 million 3D points with a fair number of materials/textures would probably count as a very complex scene which requires a graphics card with at least 5,000 PassMark points. There's more information in this FAQ post.

In addition, if you add spotlights, a Global Illumination effect and/or the Reflection effect in the Movie section, everything in your scene will have to be rendered multiple times. I'm guessing the number of 3D points that you mentioned was the 'raw' number from Build mode, not the number of 3D points that Lumion needs to render in the clip you're talking about?

To determine the exact number of 3D points that Lumion needs to render, please select the clip that you are trying to render in the Movie section, then click on the Build with effects button in the top left corner, press F7 to turn on high-quality terrain preview and F9 to turn on high-quality tree preview.

What's the number of 3D points in the top right corner?

You are kidding me.  This is a computer built for gamers.  I can't believe that it will not run this... definitely not good.  We might have to not use Lumion then and find a different program.

Either way, I did what you asked about finding the exact number of 3D points and when I build with effects (I am only using the contrail effect), and it is still at 43.5 million 3D points and 4 FPS (whatever that means). 

I still don't understand why some scenes would render successfully and others will not.  Its all the same model and I am looking at the same area in all of the scenes. 

The only lights that I am using are directional lights for typical light fixtures and the sun.  There are no omni lights or anything else like that.

Or buy a PC with a faster graphics card, whichever is cheapest for you. A laptop PC with a GTX 680M card gets over 4,000 PassMark points for example, so if portability is important to you, it's not impossible to find a portable PC with decent horsepower. Needless to say, you get way more power per $ if you buy a desktop PC.

Either way, I did what you asked about finding the exact number of 3D points and when I build with effects (I am only using the contrail effect), and it is still at 43.5 million 3D points and 4 FPS (whatever that means).
4 FPS means that the scene is updated 4 times every second (4 frames per second).

The only lights that I am using are directional lights for typical light fixtures and the sun.  There are no omni lights or anything else like that.
Omni lights are in fact 'cheap' in Lumion as they don't cast shadows. It's the directional spotlights that aren't as 'cheap' to render. If you haven't adjusted the shadow optimisation types for your spotlights, they're set to 'Accurate' by default, which means that every light causes the scene to be rendered once more. I'd highly recommend that you read the section called 'Lights with dynamic shadows' in this FAQ post to find out how to optimise the spotlights in your scene.

Since my laptop is not powerful enough, my boss was going to take this to his desktop and try there.  How do I save a Lumion file to a flash drive?  I can't even see where the saved files are stored at.

Hi johnnyboy

As you have a Pro version, the best way is that you can save your project as a single LS3 file so it can be opened from another PC:
In Lumion click on Files --> click on Export Full Scene.

Please see topic: HOW DO I LOAD A LUMION SCENE ON ANOTHER PC? in LUMION 3: Tips, Tricks and Shortcuts

Remember to close/exit Lumion on your laptop before running Lumion on the other workstation, so that the floating license for a single user license works, (unless you have multiple licenses).

On the workstation open the LS3 file by:
click on Files --> click on Import Full Scene

Hi johnnyboy,

I see that at the moment, you do not seem to have any Lumion license attached to your forum account.

As you are working for a company, you can use the floating license system of v3 for multiple staff members, as a way to get full access to the forum. We also aim to provide faster support in the Commercial User section of the forum.

All that you need to do is to ask the person who manages the license keys at your business to go to your Account settings and enter one of the license keys. You will then have full access to the forum.

Thanks in advance.
