I am getting a 'Convert Layers' Dialog on Project Open




Why is it happening ?


Both the main Mari Application as well as Mari Extension Pack sporadically update existing nodes (procedurals, adjustments etc.).

Usually this is due to a Bugfix and will not have any impact on the look of existing projects.


This dialog indicates that a version of a Node inside your project is older than the one currently installed and it is recommended to 

upgrade the Node to the latest version.

Extension Pack only applies non-look-changing updates to nodes versions.

If a node should change in look it is usually versioned up and only will take effect on new instances of the node and old projects will not prompt you to upgrade


What should I do ? 


Quite simply you should press 'Convert' at all times. It is a safe change.


I get this every time I open a project


When a project has been upgraded and saved after, the dialog should no longer appear on the next project start.


If it does appear repeatedly on the same project that might indicate a bug and I encourage you to contact me

with information what node is being upgraded.


To find out what node is being upgraded press 'Convert' and immediately after locate your Mari Log File.


Inside the Log file you can search for either phrases


    • Different Nodes:
    • About to upgrade node


.. which will show the name of the node to be upgraded




Upgrading a Project from Mari 4 to Mari 5



When upgrading a Project that was created in Mari 4 with Extension Pack, to Mari 5, the Convert Project Dialog will very likely appear.

The Mari 5 Version of Extension Pack removes a series of legacy checks from Nodes that will improve FPS count. The optimizations are non-look changing




Known issue - Extension Pack & Mari 4.7


Mari 4.7 changed the way Custom Blend Modes (such as the ones Extension Pack installs) are handled.

This triggered the Convert Project Dialog repeatedly.


This has been fixed in Mari Extension Pack 5 R7.
