Merge mesh tool gives me this error in Composer 2023.3.3
Pekka, i can’t seem to repro in 2023.1.1 or 2022.3.3 (unless you are from the future, i think you meant 2022.3.3?) on my end; both versions seem to work okay. they have v0.1.6 of the extension.
have you already tried to restart Composer and see if the issue persists?
I meant 2022.3.3 sorry.
I update to 2023.1.1 and see how it goes.
