Hi, sorry for the slow response, I keep an eye on the discord but totally forgot about the forum, in case your still curious, yes that is indeed my plugin, I’m about to update the first post with some up to date information. The plugin does indeed support mouse and roll over solutions using instanced static meshes. I would say the plugin is slightly more instanced focused, though I have plenty of standard static mesh systems as well. I have another update planned soon, which is some methods for custom map shapes, and just some general house-keeping. I will update the first post with the info as soon as its ready.
Since you wrote your own code based grid system, I hope you might find mine ok, in hindsight I would have done a few things differently, but due to it being a cpp plugin and any change to the code and unreal totally unlinks and freaks out, I won’t be changing the underlying code so I don’t break peoples setups. However, I update the blueprint side quite frequently.
