Muster 9.0.14 for Mac – 11th Sep 2019

For all Mac users of Muster

We just replaced the Mac DMG installer for version 9.0.14. Muster is now distributed as a .pkg installer and is fully signed and notarised to work with the latest versions of Apple OS and the Gatekeeper security checks.

You can find it into the download section of Muster 9.


Muster 9.0.14 released – 30th Aug 2019

We just released version 9.0.14 with new features and some bug fixes

Muster 9.0.14 is the last version for 9.0 family and it’s tagged as LTS (Long term support). That means no enhancements will be developed for this versions but bug fixes will be carried on for at least one year.

This version closes the circle implementing all the features we initially planned for 9.0. Apart from a bunch of new templates available, we add the support for reservations templates that let you lock your renderclient to allow them to work for another application. This works best in tandem with native render farm managers like VraySwam and others (it already ships with most of them implemented). We also introduces more than 30 bug fixes as well as instances borrowing (an instance can lock another instance on the same machine to enhance CPU/GPU power available for a single task) as well as limiting jobs to a certain amount of GFX available on the systems. We also developed the first release of what we call “The Universal Connector”, a unique script/code base for connectors running on Python2/3 and Pyside/Pyside2 applications , like Houdini, Maya and VRED. The initial implementation supports only Houdini (that was missing a connector until now), in the future, we’ll merge the legacy connectors code under the universal connector. There’s a lot more in 9.0.14, please have time to take look at our release notes:



Muster 9.0.13 released – 23th Apr 2019

Introducing Houdini distributed simulations with PDG support

Muster 9.0.13 introduces new engines support including VRED, VRED image slicing, LuxCoreRender, LuxRender, Terragen, Terragen image slicing, Lightwave 2019 and Modo 13 updated support. This new version brings also support for the new SideFX ground breaking technology for Houdini called PDG. You can run your simulation interactively on your render farm by cooking your nodes trough Muster directly from the Houdini GUI.

There’s a lot of more inside 9.0.13 like new filters bar in Console with fast filtering by clicking the counters icons, support for custom network messages in Python between all the Muster modules, support for Python and Pyside into Muster Notificator in response to Dispatcher messages, compressed logs files and more…

Muster 9.0.13 has been intensively tested in production environments and it is a strongly suggested update to your current version.

Muster 9.0.12 released – 14th Mar 2019

We just released version 9.0.12 with new features and some bug fixes

Muster 9.0.12 introduces new templates and fixes/enhancements to existing ones including Rhino and Sketchup. Implementing Rhino and Sketchup was possible with the introduction of the new popup handling classes in the templates system for Windows. This allows Muster to spawn GUI based rendering and automatically handle popups that may block the render process or that requires user action. We also introduced 3 new connectors: Sketchup, Keyshot and Blender in our effort to write the connectors for all the available applications. We also have in our timeline about 10 new templates that will come out in the next versions (9.0.13 and 9.0.14) as well as relative connectors. We have also fixed some minor bugs reported by our users and also introduced some enhancements (like the shared log folder for offline query, thanks to Thomas Skareteg @ Ubisoft/Massive for the suggestion).

Muster 9.0.11 released – 22th Feb 2019

We just released version 9.0.11 with new features and some bug fixes

Muster 9.0.11 introduces some brand new templates and some general fixes. Also, we have packed the Connectors, the SDK and the main application under a single installer instead of providing different downloads.
Also we included a Python command line interpreter (mpython) ready to run with the Muster SDK setup as well as PySide. This will make handling the Muster SDK a lot easier than before.
While version 9.0.11 was not planned due to the incoming release of version 9.1.0, we delayed the new version pushing some more important enhancements in the version 9.0 branch. We are going to include some new templates as well as connectors in version 9.0.12 or greather.
Version 9.1.0 that will include a switch to QT5 will come out later in 2019 and probably will be switched directly to version 9.5 due to the changes involved.

Muster 9.0.10 released – 4th Feb 2019

We just released version 9.0.10 with new features and some bug fixes

Muster 9.0.10 introduces some fixes on the Dispatcher regarding the Image assembler of single slices jobs as well as some improvements on the queue upgrade engine for older Muster databases versions.
Apart from those minor fixes, we included a lot of new templates like Clarisse 4, Guerilla Render, Renderman PRMAN Ribs render, Maya Renderman 22+, DJV, Corona standalone and Python scripts.
We also released 2 new connectors, one for Guerilla Render and one for Clarisse, this is part of our new effort to write all the connectors missing for the applications that are able to support them in the next months.
We have also introduced some improvements like the addition of a function to automatically insert a chunk’s renderer inside the job’s excluded pools as well as other minor improvements.
This will be the latest release of version 9.0, we almost completed the complete port of Muster to QT 5 along with some new features that will come out as version 9.1.0 soon.

Muster 9.0.9 released – 26th Nov 2018

We just released version 9.0.9 with new features and some bug fixes

We just released 9.0.9 that includes a major fix for mrtool when used using the deprecated “-sf” and “-ef” flags. We also fixed a bug on the renderclient that prevent the usage of the “shutdown when idle” and “shutdown when paused” functions. We have also optimised the way jobs and nodes are sort after being retrieved by Dispatcher and now the operation is extremely faster on the Console side. The Console also gains two new configurations combo to allow use to disable the warnings messages about pools and users configuration from another session.

Muster 9.0.8 released – 11th Nov 2018

We just released version 9.0.8 with new features and some bug fixes

We just released 9.0.8 that includes new features and minor bugs fixes. We implemented a workaround for a Windows 7 bug where a connection versus the Dispatcher was not possible on a system with a dual NIC card where IPV6 was disabled on one of the NICs. This lead the network stack to take a wrong routing failing the connection. We also implemented the Katana render as well as fixed some additional minor bugs.

Muster 9.0.7 released – 10th Oct 2018

We just released version 9.0.7 with new features and some bug fixes

We just released 9.0.7 that includes new features and minor bugs fixes. We have reworked the way the maximum nodes on folders are calculated providing a more consistent result. We also included the maximum nodes field in the broadcast jobs that was not available before. Also reparsing a chunk log in the chunks view no longer ignore the chunks process exit code and gives a correct result. We also have included menu items in the popup to allow the end user to override the exit codes in the existing job.

Muster 9.0.6 released – 26th Sep 2018

We just released version 9.0.6 with new features and some bug fixes

We just released 9.0.6 that includes new features like being possible to purge existing pools from no longer existing nodes. We also made the size of the icons and rows of the main Console’s panes configurable from the preferences. We also addresses some bugs on the Dispatcher that may cause deadlocks under rare circumstances as well as speeding up the jobs submission phase. Also the realtime statistics storage with the chunks has been proved to be somewhat heavy for the default Sqlite database. We disabled such feature by default, now a warning is shown if you try to enable it suggesting the usage of a different DB backend.

Muster 9.0.5 released – 28th Aug 2018
Muster 8.6.20 released too

We just released version 9.0.5 with new features and a critical bug fix on Windows (version 8.6.20 released too)

We just released 9.0.5 that includes new features and address a critical bug on the Windows platform. Due to the bug nature, we also released a 8.6.20 version for users still running version 8. The bug affects the way process outputs are collected and may lead a client to an unresponsiveness state until a render is completed. The bug is very rare and may produce keep alive disconnections from the Dispatcher and/or from the client. If you’re experiencing unwanted disconnection due to keep alive, the update is mandatory.

9.0.5 also introduces some nice new features for realtime statistics for either the render nodes and the Dispatcher. The Dispatcher statistics window has been enhanced to include cpu usage, memory usage, network cards usage and disks usage. The same informations are now available to the nodes using the “Realtime statistics” option in the nodes popup menu. Also depending on the configuration on the Dispatcher, statistics can be store side-by-side with chunks allowing the browsing of nodes usages on a chunks basis. Also, depending on the Dispatcher configuration, statistics can be stored in the history chunks.

Muster 9.0.4 released – 29th May 2018

We just released version 9.0.4 with 2 critical bugs fixes

We just released 9.0.4 that fixes 2 important bugs present in 9.0.3.

9.0.3 introduced some code changes in the web server handling and this caused a bug in the queue submission system. It was not possible to submit a job through the WEB REST API and through the web interface. 9.0.4 address this and also no longer applies the substitution path engine on the custom environment field of the jobs submitted through Console. This made impossible to keep values with a forward slash on the Windows environment.

Muster 9.0.3 released – 15th May 2018

We just released version 9.0.3 with some new features and bugs fixes

The latest version of Muster 9 has just been released. As announced before, we introduced the support to the MongoDB database. Also, to help users migrate between databases, it’s now possible to export your queue or your settings (pools, users and repositories) to pure JSON files. Those files can be re-imported into a different DB technology making the migration and also an universal data backup possible.

We also introduced a new graphs plotting library that is part of the new reporting system we are working on.

We also made some minor stability fixes and add templates icons to the submission view and the queue view. For further information read the release notes on our wiki!




Muster 9.0.2 released – 6th April 2018

We just released version 9.0.2 with some new features and bugs fixes

The latest version of Muster 9 has just been released. While we prepared the code base to host the support to the announced MongoDB support, this is an intermediate bugs and improvements release. We fixed several behaviours on various components but the most important thing is that Muster 9.0.2 is now able to upgrade and normalise a Muster 8 database. You can now update to the latest version retaining your queue files and the settings for users, pools and repositories. We also included some improvements in the sequences viewer. You can now fix the 1:1 and FIT settings as default, and you can also mark frames and chunks using the CTRL, SHIFT and ALT keys while dragging the timeline.
