I have an error when trying to use the tool:

Invalid source /obj/geo2/sop_detail_mesh1/polyfill1
Error: ‘hedgegroup’ is not a valid group..

Hi, this seems similar to a problem mentioned above. (Which was solved)
Could you try updating your toolset to latest to see if my fix works?

If you already did that, could you perhaps post a simple example where I can reproduce the issue?

Eagerly waiting…

This will happen post-GDC.

Any idea what I've done wrong please?
Could you email your log files (found in the cache folders) to support? I will then take a look at it for you!

This is due to the plugin not being compatible with version 2.1.0 of AliceVision yet. Please try using 2.0.0 instead and you should not be getting that error.
