Version 2 is Cross-platform for Mac OS X & Windows!
Drag-and-drop-dead-easy™ background rendering while you continue to work in LightWave Layout.
DLI_SNUB-Launcher™ – DreamLight Interactive ScreamerNet UB Launcher is a cross-platform GUI front end interface to interactively build the necessary command lines to launch LightWave 3D’s ScreamerNet UB standalone, batch and network rendering component (LWSN) on both Mac OS X and Windows.
DLI SNUB Launcher works by itself for drag-and-drop standalone background rendering with LightWave ScreamerNet LWSN on a single computer. It also works together with our network render controller – DreamLight Constellation, for cross-platform network rendering on Mac OS X Macs and Windows PCs.
DLI SNUB Launcher 2 was completely rebuilt from the ground up as a cross-platform Mac/Win LiveCode application with additional features including red/green auto-highlighting file path fields for easy at-a-glance path verification and a new standalone scene settings panel with user override abilities for drag-and-drop standalone rendering that’s never been easier. The DLI_SNUB-Launcher 2 is compatible with LightWave 3D 2015+ on Mac OS X 10.6.8-10.11.6+ and Windows 7,10+. Legacy versions are still available for older versions of LightWave 3D on Mac OS X.
I created DLI SNUB Launcher while updating my Mastering LightWave 3D ScreamerNet LWSN white paper (NewTek based the Mac network rendering chapter of the LightWave 3D manual on our white paper) and tutorials for ScreamerNet lwsn UB (Universal Binary for both PowerPC and Intel processors). After carefully writing out the explanations for how to configure and launch ScreamerNet lwsn in Terminal, I felt that it wasn’t quite Mac friendly enough. So I set about writing the original version of DLI_SNUB-Launcher as an Aqua GUI interface in Apple XCode to interactively build the command lines and launch multiple ScreamerNet lwsn render nodes for standalone, batch and network rendering. (Render nodes are instances of LWSN, normally one per computer.) Now with version 2, I’ve rewritten DLI_SNUB-Launcher from the ground up in the cross-platform LiveCode in order to bring our famous drag-and-drop-dead-easy™ ScreamerNet rendering to LightWave 3D’s Windows users as well.
NewTek based the Mac section of the Distributed Rendering chapter in the LightWave 3D manual on our Mastering LightWave 3D ScreamerNet LWSN white paper.

DLI SNUB Launcher Customer Testimonial
I really wished I’d filmed this… I’m already rendering !!! I literally got the license a few minutes ago …. that was the quickest time I’ve ever set up anything…
Screamernet has literally brought me to tears in the past – in the fetal position on the ground… I cannot believe how simple this was, how it gives you enough control to know what’s going on and shows you what it’s doing… wow..
I’m very happy with your product. Initially I was waiting for things to fail, or not work.. But it just worked. First time! I got my render back in one hour instead of 7!
all the best,
p.s. In the past I was used to the IT people back at Digital Domain dealing with all of this, when we had literally thousands of machines at our disposal, I’ve now left LA and set up a studio in Nairobi, Kenya ! and I’m doing it all myself… Thank-you for making this part so simple, I was expecting insane headaches.

DLI SNUB Launcher Manual
Download & Installation
- Download DLI_SNUB-Launcher by right clicking on the link below and selecting Download Linked File from the pop-up menu. Or download the DreamLight Constellation & DLI_SNUB-Launcher Bundle for both together.
(NEW Cross-platform LiveCode version for Mac OS X + Windows LightWave 3D 2015+)
Includes LW11+ DLI_SuperBalls Benchmark Scene & Legacy Mac 1.8 Version of DLI_SNUB-Launcher
- After downloading the DLI_SNUB-Launcher.zip file, unzip the file by double-clicking it on Mac OS X or by right-clicking on it and selecting Extract All…
- Drag the DLI_SNUB-Launcher application file from the unzipped folder to your LightWave 3D applications folder where Layout and Modeler are found:
/Applications/NewTek/LightWave3D_2015.2on Mac OS X or
C:\Program Files\NewTek\LightWave_2015.2on Windows. Enter an administrator’s username and password if prompted. You may then create an alias/shortcut to place on your desktop if desired.
The first time DLI_SNUB-Launcher 2 is launched it will search for Layout in the same folder (or the highest version installed if not in the same folder) to determine which version of LightWave you have. It will then search for the
bin/lwsn command line application in the LightWave3D folder.
It will next search for the config folder where LightWave’s config files are stored. For Mac users It will first look for a custom Preferences folder that you may have created inside the LightWave3D folder to use as the config folder. If not found, then the default config folder in the current user’s Application Support folder will be used instead.
The default config folder is found in the following location:
Mac OS X:
When found, the lwsn Path and Config Folder fields will be highlighted in green. If either is highlighted in red instead then it was not found successfully and needs to be manually set. To manually configure DLI_SNUB-Launcher for a custom configuration simply drag the ScreamerNet lwsn command line application to the lwsn Path button or field and/or drag your desired config folder to the -c Config Folder button or field. Then set any other settings as desired.[NOTE: The FREE LITE version of DLI_SNUB-Launcher does not save custom settings between launches other than the lwsn Path setting. Any other settings that are manually configured will need to be reset each time it is launched unless you purchase a registered license.]
To drag-and-drop render a scene, simply drag-and-drop the scene file onto the DLI_SNUB-Launcher application icon on the desktop or the dock/task bar (no need to launch DLI_SNUB-Launcher first) and it will first open the new Scene Settings Panel where you may set the RGB Output path, image file name, image format and render range. When done it will launch lwsn to render the scene. It will prompt you to change the Content Folder if necessary.
For more examples of using DLI_SNUB-Launcher for standalone rendering, batch rendering and network rendering check out our quick-start tutorials.
If you ever wish to uninstall it, simply drag the DLI_SNUB-Launcher application file to the trash.

Support & Troubleshooting
Always verify that you have the latest build of DreamLight Constellation and/or DLI_SNUB-Launcher based on the version numbers. Download and install the latest version if you’re running an older version and retest any issues with the latest version. We often fix any bugs we find or that are reported by users and post new builds with fixes as soon as possible. You may also review the Version History to see if a fix for any issue you may have encountered is reported as fixed.
If you’re having trouble getting ScreamerNet lwsn to work with DLI_SNUB-Launcher, please test rendering the included DLI_SuperBalls test scene tutorials first. Start with the Standalone Rendering tutorial and then the Batch Rendering tutorial. This will show you how to use DLI_SNUB-Launcher properly by testing it on known content in a known configuration. Many problems turn out to be problems with your custom content or custom configuration, often with network access and/or read/write permission issues to your network content.
Next review our Mastering LightWave 3D ScreamerNet LWSN white paper, going through all the included tutorials to be sure that you’re configuring ScreamerNet and preparing your scenes correctly for ScreamerNet rendering.
Also verify that all nodes are using proper paths that are valid for all nodes and users across the network and that read/write permissions are set correctly for all users, files and folders.
All computers must have read access to the same Content Folder and they must all have read/write access to the same Commands Folder and RGB Output Folder. All the paths must be identical to each of those folders for each lwsn node on each computer. If you wish to use different local/remote paths or mixed cross-platform paths then you would need to use a third-party render controller because LightWave Layout’s built-in Network Render panel does not re-map paths for local/remote or cross-platform support.
All settings are saved in the DLI_SNUB-Launcher preferences file found in the following locations:
Mac OS X:
If you’ve verified that your configs and scenes are set up correctly, and you’re still having problems with DLI_SNUB-Launcher, the next thing to try is to delete the DLI_SNUB-Launcher preferences file to verify it hasn’t become corrupted. Then launch and set up all your DLI_SNUB-Launcher settings again.
What DLI_SNUB-Launcher does is build the ScreamerNet command line and then launch lwsn. Once lwsn is launched and running DLI_SNUB-Launcher is no longer involved, in any matter whatsoever, so if lwsn is crashing or having other issues like not saving images, that wouldn’t be related to DLI_SNUB-Launcher itself but would most likely be incorrect paths, incorrect permissions, a bug in lwsn, problems with the content being rendered or plugins that are being used.
We will fix any bugs that are found and fixable within DreamLight Constellation and/or DLI_SNUB-Launcher, but are unable to fix any bugs in LightWave 3D ScreamerNet LWSN itself. If you think you’ve found a bug in DreamLight Constellation and/or DLI_SNUB-Launcher please try to render the scene directly in LightWave 3D ScreamerNet LWSN alone using LightWave’s built-in network render panel. That’s the best way to rule out any LightWave 3D ScreamerNet LWSN bugs.
Please report any issues or problems through our Contact Form. While we can’t troubleshoot your custom setup, we can often point you in the right direction and we respond to email support inquiries as soon as possible. We do not have telephone tech support, so no phone calls please.
