When I create a Spline from here I can’t add more points with Alt+Move the point.
Why?

Thank you, Senpai!
It’s not a spline that you’re creating.
It’s an actor with an inherited Spline Mesh Component. This actor does not have an editable spline you’re thinking about.
In order to edit spline points, you need a Spline Component. You can then take a Spline Mesh Component and stretch it between each point of a Spline Component (which can have many points).

What is the “Spline Mesh Actor” used for, I cannot find any information on it.
It’s nothing more than an actor with a spline mesh component inside of it. You can create an actor and add spline mesh comp manually from the dropdown or you can have the engine automate it a bit. You cannot find any info on because there’s probably nothing to talk about. It’s simpler than you think.

Thank you for the reply! and for anyone else that stumbles on this post here is what GPT says:
In Unreal Engine 5, the Spline Mesh Actor is a specialized actor that incorporates a Spline Mesh Component. This component allows a static mesh to be deformed along a spline curve, enabling the creation of smoothly curved meshes like roads, pipes, or rails.
However, the Spline Mesh Actor is designed with a fixed spline that has only two control points, corresponding to the start and end positions of the mesh. This design means you cannot add additional spline points directly to the Spline Mesh Actor within the editor. As noted in community discussions, “A Spline Mesh only has two control points as it’s only a single Spline Mesh.”
To create more complex shapes with multiple spline points, you can use a Spline Component within a Blueprint. This approach involves creating an Actor Blueprint, adding a Spline Component to it, and then using multiple Spline Mesh Components to stretch between each pair of spline points. This method provides greater flexibility and control over the mesh’s deformation along the spline path.
