WARNING: using XXX.xxx in module Main conflicts with an existing identifier

Hi, so basically you got it correct: you’re importing the identifier Mesh from two different modules and so Julia is warning you that you probably need to make sure that you’re using the right identifier in your code. You can do that, for example, with

using GLMakie
using GeometryBasics
const Mesh = GeometryBasics.Mesh

That way it’s absolutely clear which identifier the compiler should use. You can still access the other one with GLMakie.Mesh.
