Dynamo Sandbox geometry nodes stopped working

I have been successfully compiling and using Dynamo Sandbox for a while now, while Dynamo was checking out the license from Autodesk Alias on my machine for the geometry nodes (I think). Around a certain commit date however, Dynamo started to fail finding the LibG binaries needed to run any geometry node.

I suspect commit fe807ad6 to have introduced the “problem” for me, but I might be wrong.

Dynamo version that still works for me is according to splash screen. Any version after that fails to find the needed licenses and throws errors on the geometry nodes like Circle.ByPlaneRadius etc etc.

Am I doing something wrong on my end?

Perhaps it is looking for a newer geometry library (ie: 2.9 wants LibG version n+1 but you may only have LibG version n+0).

What version of Alias do you have installed?

Sounds reasonable. I’m using AliasSurface 2021 Update 1 here, afaik the most recent version currently.

I’m returning to this topic because I still cannot get any of the Sandbox versions (downloaded or self-compiled) to work with the Alias license somehow. Currently on Alias 2022.1, that version comes with the latest libg 227 version:

They also do work fine when I launch Dynamo from within Alias. But running Dynamo Sandbox, they just don’t get picked up ever:

The Dynamo version shipped with Alias is Dynamo
Is there a step I’m missing?

try the -gp flag presented in this thread:

you can use it to point to the autodesk geometry libraries when starting sandbox.

Thanks for your input @Michael_Kirschner2 - this indeed did the trick! For Alias, the folder that had to be used was C:\Program Files\Autodesk\AliasSurface2022.1\Dynamo\Dynamo Core\2\ASM

When creating a link with this flag as described the libraries are found and used, awesome!
