I am working on my own train-simulation project
I tried to use spline to definite the railway, and use the spline mesh component to do the visual job.
In order to prevent the mesh of the rail from being overstretched, I want a series of spline meshes to be covered with a control spline with a fixed length, but in practice, I find that if I use the tangent of the control spline as the tangent of the spline mesh, the spline mesh will be greatly distorted.
I want spline meshes to cover the control spline with the same curvature. I don’t know what to do. Maybe I need to find the relationship between the tangent of spline and the curvature of spline in UE4
