After installing the addons in the user preferences, they don't show up anywhere in blender 2.8 except from workspace addons tab in the properties and clicking it doesnt do anything. In user preferences next to the addons list, it also says that "Upgrade to 2.8x required". Does that mean that we can't use any addons in 2.8 unless they are upgraded for 2.8 builds?
Blender 2.8 has yet to notify the add-on developers to make it compatible with 2.8.
If you see a message stating "Upgrade to 2.8x required" it means the addon was made for older versions of Blender 2.7x and does not work for newer versions.
Unfortunately there is very little you can do as a user to fix it.
Check the author website for an newer updated version, or ask the developer for an update. Most addons require small changes to adapt and can be easily updated.
If it is a commercial addon you payed for try contacting support for an update. It is often in the best interest of the owners to make it work in the latest release.
Otherwise roll up your sleeves, learn Python, and update the addon yourself by coding in the required changes in. Most addons require only small adjustments.
Ok the addons are in the addons in the preferences in 2.80 the mesh 2 is there
But I am missing the measuremnts and the snap utils that used to show up in the T toolbar. Tool bar T is missing now.
Someone else must be scratching there head about why the addons are included with 2.80 but no person can find them to use them.
