I found one way to pass the issues that I’m having with preview actor…maybe an bug or unhandled exception…below the steps that I use on a fresh project:
1º Create project, activate the Able Ability System in plugins list and restart the project;
2º Go in character BP and add Ability Component;
3 Create some ability BP;
4º Cancel the first windows that show all ue4 + plugin classes;
5º Now only show the classes from the project…here I select my character BP;
6º On editor…when not showing nothing…I click on preview mesh that I select before (at toolbar) and him will be shown.
Improvements: This steps above are not explain in tutorials.
Maybe another problems, bugs or unhandle exceptions:
1º When I try rotate my character mesh on Ability Editor, the preview of Ability with all tasks don’t work;
2º I try to rotate my mesh and camera in character BP and back to Ability Editor…when I hit play the UE4 crash;
3º If I click on validate button in toolbar, the UE4 Crash;
If you need I can post some screenshots or upload the project…
PS> I’m using the UE4.21.2.
Right that you will fix\improve all,
