I imported a 3D modele in gltf.
In this model are many meshes, with different materials.
mesh number 1 and mesh number 5 are the same color (same material indeed).
When I modify the color of mesh number 1 (mesh1.material.emissive.set(mycolor) ), it will change also the color of mesh number 5. So I assume it’s because they share the same instance of “material” somehow.
What is the right way in this condition to change the color only of the mesh 1 ?
(my goal is to just change the emissive, but keep the original material color as it is).
And by the way, is there an easy way to make a “flashing” material? I wanna make the mesh flashing at low frequency while it is moving.
