Hi!) I don’t speak English very well, so it’s very difficult to explain) I carefully explored your code, looked a few tutorials on creating blueprints, then on how to add spline mesh and spline to them, and how to configure it. I had the task of making a water projectile, so the deformation of the model was important. I repeated the code one by one, but there was no result. Because when I created the Add Spline Mesh Component, I didn’t add my static mesh to it. After everything worked!) But now I’m trying to understand how to add a particle system to this projectile) The particle system does not want to connect to the nodes known to me in the spline blue print. So there is something to do)
