Verlet integration via Blueprint (rope)

Im trying to make a rope/cable simulation using Verlet integration. I’m making it blueprints only, since im not a good programmer and cant write on c++

Right now its working pretty well, but there is some strange things going on - when im fixing first and last points, instead of making perfect arc my “rope” is shrinking to one side mostly. I think the problem is in my constraints solver algorithm. If someone could take a look at my blueprint, i would be rly glad :slight_smile:


Pls help me solve this problem. Here is my [blueprint file][3]
