I am having trouble getting BNR to render frames using Messiah Studio?

Messiah Studio needs to be installed Locally on each RenderNode machine. Please make sure you install Messiah Studio in the same directory on each machine.

Issues in submitting a render job continue to receive the following error: ERROR – LOAD ERROR – (Check paths) – Scene Error -3. Why is that happening?

This is a issue with BNR reading the Lightwave settings in a lws scene file (where a animation plugin is missing a tag).  You will need to update to a newer version of BNR to resolve this.

Frame not Found error -but frame is created?

If the frame is getting created -but BNR doesn’t find it.  I usually is because the output format is not getting matched correctly with the different lightwave formats.

NewTek has made many changes of the output format over the years – Suggest using these types that have not changed:


————– History of changes to the ‘Output Format’ —————-
NewTek changed the numbering order of the output format for LW9.3.1.
They added new formats and changed the number order that makes it
incompatible with previous LW versions and it may cause image output
problems when people try to render scenes between this version and older
ones. This affects the “OutputFilenameFormat” setting stored in the LW

Here is a list of the affected output formats:

< LW9.3    LW9.3.1
“Name_001”        4       8
“”    5       9
“Name_0001”       6       10
“”   7       11

Then in LW10 they changed it to (they switch 4,5,6,7 with 8,9,10,11)
0 = “Name001
1 = “
2 = “Name0001
3 = “

4 = “Name00001
5 = “
6 = “Name000001
7 = “

8 = “Name_001
9 = “”
10 = “Name_0001”
11 = “”

12 = “Name_00001”
13 = “”
14 = “Name_000001”
15 = “”

Then LW 11 they changed it again: (they switched 8,9,10,11 with 4,5,6,7)

0 = “Name001
1 = “
2 = “Name0001
3 = “

4 = “Name_001
5 = “
6 = “Name_0001
7 = “

8 = “Name00001
9 = “
10 = “Name000001
11 = “

12 = “Name_00001
13 = “
14 = “Name_000001
15 = “

**** So you best options to use – to skip most of these issues is to try using these instead:
12 = “Name_00001
13 = “
14 = “Name_000001
15 = “

I’m running the BNR Controller an a Windows 2003 with SP1 and the Rendernodes are taking a long time to connect.

Windows 2003 with SP1 added a change to the Socket message size – Please install the HotFix 898060 to resolve this issue.

I’m having trouble getting BNR to render the Scene First in First out in the Professional Version?

Open the Controller Options->Configure->Priority

Please select FIFO check box. If you not satisfied with result behavior,
Please set the number or rendernodes you would like for each priority level (‘Low,Normal,and High Max RenderNodes’)

I am unable to load a scene. The program looks like it freezes at one point and will not finish loading the scene, no matter how much time I give it – it doesn’t finish?

On Windows 7 it seems a message box might get hidden by the main window:

You may need to ‘alt-tab’ to see if a message window is hidden behind the main window
(As this might make the program look like its frozen, but in fact its just waiting for a click on a message window)

I upgrade to the Studio version – but only 15 rendernodes are being used

In the Options->Configure->Priority
Confirm the Priority for each level are set to the correct number of rendernodes.

The default is 15 rendernodes.

Why am I getting image not found using Windows 2008 server – but the images are getting created?

Windows 2008 Server supports a new sharing file system called SMB2.  Which may cause problems when connecting to XP or older OS machines.  To solve this issue – you will need to disable the SMB2 support on all clients and servers (Vista, Windows 7, and Windows 2008)

I Don’t understand the Priority system in BNR – Can you explain how this works.

There are 2 factors that control the Priority
1. Priority Level = Low, Normal, High, Take Over
2. Priority Order = 1-32757

A Scene with ‘Level: High’ will run before a Scene with ‘Level: Normal’
A Scene with ‘Level: Normal’ will run before a Scene with ‘Level: Low’
A Scene with ‘Level: Take Over’ is a special level -that can be used to Take over all the rendernodes – for emergency jobs.

Now inside each ‘Priority Level’ the scenes will run in the ‘Priority Order’ So: A Scene with ‘Level: Normal’ and ‘Order: 1’ will run before ‘Level: Normal’ and ‘Order: 2’

The FIFO setting in Options->Configure Priority is used to set the increase the Priority Order each time you add a scene to the queue. (FIFO – First in First out)

Please see Tree View below for a visual map of how this works:

Priority Flow.


Where are the configuration setting kept?

On windows BNR stores the configuration settings in cfg files located here:

Win2000/XP machine:
C:\Documents and Settings\All Users\Application Data\ButterflyNetRender\

Vista/Windows 7,8,10:

The render shells are not displaying any information on the RenderNodes. It only displays: “LightWave x86 ScreamerNet Module (Build” then nothing else?

When you enable the Logging.  The LWSN (LightWave renderer) output is captured to a file.
Please check the ‘load…’ and ‘render…’ logs to check for any Lightwave rendering issues.

Kray doesn’t find the license?

Make sure you place the license key for Kray in the Configure folder on the network where BNR has installed the LightWave plugins.

I keep gettng a error when rendering – how do I fix this?

Check the Log Tab to find text log files:

launch*.txt = command to start rendering
load*.txt = log of loading the scene
render*.txt = log of rendering the scene

Check each log file for any error messages to figure out what might be wrong.

It might be a missing plugin or object file.

I keep getting LWSN crashes with a Texture sequence in my scene – How do I fix this?

Make sure you are only using 1 thread during rendering.
In the BNR Config Lightwave settings (Configure Platforms->LightWave tab) set the Render Threads to 1.

I have frame ranges 1000-2000 and output format why can’t BNR find the output frames that LightWave LWSN creates during rendering?

You need to set the output format to fit your frame range – use

Does the LightWave option use the LWSN -2 or LWSN -3 on the render nodes?

I’m using the LWSN -2 option to give BNR more control over the render nodes. And this also gives me the ability to not have to reload the Scenes each time it renders a frame(s).

However if you want to use the LWSN -3 (Batch mode) option – this is also available.

Do I need to setup Screamernet before I can use BNR with LightWave?

No, BNR will set this up for you with the Automatic setup feature. All you have to do is install BNR on the same machine that you have Lightwave installed on and you must have a shared network directory that all your machines can access, BNR will do the rest!.

You will need to make sure the LightWave cfg files are created by Launching Lightwave Layout and ‘Clear’ and ‘Rescan’ the plugins, then exiting Layout.

I am having trouble getting BNR to verify the frames with Maya? Frame(1) not found!

ButterflyNetRender requires the Maya scene to be saved with a Frame Ext of ‘Name.####.ext’

Can BNR Read the Render Global from a Maya binary .mb file?

No, Currently BNR can read the Render Globals from the Maya .ma file – but not the .mb file – you will have to set the render settings after you load a .mb file.

How do I setup Modo with BNR?

You can setup Modo with the BNR Setup Wizard – this will copy all the files required for network rendering.

Is each Processor in a Multi-Core system considered a Render Node?

Yes it could, but, you could configure the rendernodes to use all CPU’s or a single CPU/Core in a multiprocessor system.

So you are not locked into using a rendernode per CPU/Core – you can configure them depending on the type or render system you will be using.

How does the Controller talk to the Clients?

The Controller and Client communicate via TCP/IP.

ButterflyNetRender 4.x:
Socket Ports 5600-5699, 6600-6625, 7600-7615.

ButterflyNetRender 5.x, 6.x, 7.x :
5950-6100 – BNR Client connect sockets
6516-6546 – Remote Sockets for viewers
7880-7900 – BNR Client command sockets

Make sure your firewall (if enabled) has these ports open so the applications can talk with each other.

How do I figure out the IP Address of my Computer?

In the BNR Controller – Select the Options->Controller Information.

CS6 network rendering not working
Can I run the Client on the Machine that’s running the Controller?

Yes, Just install the client after you install the controller and configure it with this machines IP address.

I’ve installed the BNR Controller and BNR Client and set the correctly IP Address for the Controller in the Client – but it doesn’t connect?

Please confirm you are not running a Firewall on the Controller machine or Client machines.
