I think the reason why people say they don't merge correctly is because they're probably using OctopusHorizon's 2.0 Models and not [404] RetroGary's 2.0 models. They don't seem to merge right with the former but I think they're partially compatible (outside of a clipping issue for the long gloves) with the latter.

Will there be a 1.0 version of it?

Could just be me but when using the 2.0 Models there's a clipping issue with all of em it seems.

I love these, if only they worked for the splatoon 2 octoling models I use, the enhanced 2.0 models dont even let you move their heads and stuff- they have a serious lack of articulation.

Two things:

One, I think I speak for everyone when I say a 1.0 model would be a nice addon. Maybe you could consider it in the future?
Two, to prevent from clipping on the models, would you consider making wrist-length and/or hand gloves as well?

Other than that, this is a nice addon pack so far. It seems to work best with the Ragdoll Mover Addon, personally.

I love this! Sad that didn't work for Enhanced Inklings 1.0 and Octolings.
