Materials not loading in 2022

As usual, I moved the Materials, Templates and Plugins folders from 2021 to 2022. However, some of the materials did not load. Looking at it more closely I found out that the materials not loaded are all jpgs, not skms (the usual extension for Sketchup materials).

Does anyone know why they worked in 2021 and do not in 2022? Is there a way to make them work?

Thanks.

Are you sure the .jpg’s loaded in SU2021? Materials need to be .skm files to be recognized as materials by SketchUp.

Moving the plugins from an older installation to the newer one can be risky. Some extensions may not load due to incorrect installation. Some may need to be updated to work with the newer version. Best practice is to install fresh from their sources.
