I have noticed that the “Set Collision Enabled” node causes a significant performance hit, as can be seen in the video below. It is called on each mesh along the spline, which there are a total of roundabout 40 in the video shown. It makes placing the spline almost impossible, as it takes up to 2 seconds to generate all the meshes necessary.
It shall be noted that I am on linux, and that might be the cause of the issue, although somebody more qualified than me should probably investigate this.
Does anybody have a clue why this is and how one could resolve the issue?
