To anyone wondering. I fixed the raycast lines that were flashing red and green and the -90,000 issue. This is because I put put the scene components at the bottom corners of the cube instead of at the corners on the “0” Z axis as in the video. This, for some reason, stopped the red and green flashing raycast lines and now they are solid red and I was able to change the suspention strength to 90000 instead of -90000 now.
However, the end result is still the same. the box car bounces around like a wild bull. lol. After about 3 weeks and a few other Blueprints tutorials… I’m not sure if I should scrap this project and start over with a Chaos Vehicles tutorial, or stick with it and learn more about raycasting.
