As a developer of a train game, I tend to use long parts like rails often. But one thing I’ve noticed is that when I test the game on the Roblox Game Client, parts like these shift orientation very slightly but the ends of the part do not line up with the next. My suspicion is that the game client doesn’t allow for as many decimal places for precision as Studio does when it comes to object orientation or position.
This problem has been going on for a while and I hope that it will be fixed sometime soon. If anyone has any clarification questions for me I’d be happy to answer them!
I hope that the Roblox Client will soon allow for more precision of part orientation, and that my game will be able to have smooth tracks in-game just as they look in Roblox Studio!
EDIT: Yes, these parts were anchored
