Thank you for your response, and providing these links.
I checked Media Texture and in theory, that’s exactly the approach, loading a set of textures and animating them using the Normal Map channel, on a mesh.
I haven’t found a way to use textures located “Outside of Content”, as with Editor Only it’s
possible and that would be a solution, but the project will be packed, which based on the tooltip description, it will lose the reference to the location, outside of content folder.
Maybe a workaround can solve this, but most likely it’s going to require Engine modification.
