That putt was smashed.

I have done some testing in the GNCD and found that when placing pins on greens in areas of slope it effects this "glitch". The more dramatic the slope the pin is placed on the more this "glitched" occurred. It almost seems that there is an invisible lip created on the side of the hole towards the upper part of the slope. I used the soft fuzzy brush directly over the hole to flatten the hole and it seemed to alleviate this issue. Can anyone else confirm this? If this is the case then it should be the required practice if designers are resorting to tricked out hole placement in order to keep scores down. This glitch happens to me so often I pretty much expect to see it around 3 or 4 times a round at times...and worse than the example shown in the OP. It's been an ongoing issue since day one and I'm shocked that it has taken this long for someone to actually pin point a possible solution. Hat's off |

Yep... When this happens to me, I know it's about to happen because I know I struck the putt to firm.. |

Never happens uphill in my experience. It's always side/down-hill. Thus IMO it is in fact a glitch bcs otherwise it would happen uphill as well.

I'm just guessing here, but I'm guessing that the hole it self is flat and when placed on a slope it can create this glitch at certain angles as there is an invisible edge on the cup. If this is the case it would be more prominent the steeper the slope is. I don't for one second think any designer use this "trick" on purpose if this is the case. I for one don't.
I'm also guessing this is related to how green grids are shown. What I mean is that at certain angles it might appear yellow when in most other angles it's green.
I have no basis for this theory really. Just brainstorming .

HB Studios knows about the issue and has promised to address it in TGC2. The issue has something to do with the timing of collision checks between the ball and the ground and cup.
Sometimes, the collision check happens too late. If you're putting downhill, then this would cause the ball to momentarily float above the ground. Now, the ball has a farther distance to travel downward in order to come to rest in the cup. Sometimes, this doesn't happen quickly enough and instead hitting the back of the cup well below its rim - and falling into the hole - the ball catches the back lip of the cup and "hops" slightly behind the hole.
In more drastic conditions, the ball has to travel so far downward, that it actually doesn't touch the ground again until it is completely behind the cup. Graphically, this would appear to be "the ball rolling right over the hole".
Technically, the ball doesn't travel smoothly. Its position is updated a little bit each frame by multiplying the velocity vector by the amount of time since the previous frame refresh. Sometimes, if the interval between frame refreshes is longer than usual (and we're talking in terms of milliseconds), this can happen, especially when vertical displacement is dependent upon the force of gravity. Applying gravity is dependent upon there being some distance between the ball and the ground. Since gravitational force is applied as acceleration, the distance gravity will move an object over a very short period of time is extremely small, meaning the ball would not fall as quickly as it should (because the force of gravity was applied too late). All of these factors collaborate to cause the issue you see with good putts not falling.
This is one of a small handful of collision issues HB promises to address in TGC2, which is written on an upgraded version of the Unity3D engine. If the collision checks can happen more frequently, the better the game will represent the expected interaction between the ball, the ground, and the hole.

A lot more putts "glitch" out on downhill sliders IRL too. It's just basic physics. For an uphill putt the hole wants to suck the ball in, for down- and sidehill era it wants to reject it. |

The issue in the game is not that the ball does not drop its that it goes of fun the wrong direction sometimes in the interaction with the rim. Most of these were never supposed to drop, but they should not lip out in the way they do.
I don't like that the physics are off but having a slight variance in the holes is fine. In golf - you get screwed by the universe all the time, it's part of what makes golf the great game it is.

Anyone got a video of this happening on a putt the would have only rolled a couple of inches past the hole if missed?
This just doesn't happen to me unless I simply putt it too hard/fast.
This may be due to how I'm putting, I putt so that if I miss, I'm very close, under a foot is the goal.
Now I do get the bug that has the left or right edge reject the ball and kick it the wrong way, that one baffles me.

You need to adapt your speed to the putt at hand. < 1 foot sounds like you are too defensive with grids. But more than one way to skin the cat... Without grids distance control becomes crucial as it's possible to miss a four footer coming back. Grids make it too beneficial to power through breaks anyway so in a way it's not so bad that this bug exists. |

I putt the same whether it be with or without grids, I don't need to adjust anything.

Anybody that has any question just ask Mcbooga bcs he's seems to think he has it all figured out. |

The video is actually a bad example of the real glitch. The glitch I endure many times is the ball rolling over the hole even on a perfectly centered putt from as little as 2 ft away. Rolls over like the hole isn't even there. That is the true glitch in putting.

This may be due to how I'm putting, I putt so that if I miss, I'm very close, under a foot is the goal. I've never seen it where the putt was so soft it would stop within a few inches. However, I've seen it where the ball would roll 2-3 feet past, and I know for certain I've slammed putts in with even more speed than that. But, yes, speed is a factor because the force of gravity is applied later and the ball "floats" for a split second. This is also more likely to happen when the frame rate drops because all the calculations are refreshed each time the screen is drawn. This isn't truly a bug in the source code, so much as it is a result of several factors affecting the timing of the calculations. If HB is successful in optimizing the performance using Unity3D V5, then we should see less of this in TGC2. Now I do get the bug that has the left or right edge reject the ball and kick it the wrong way, that one baffles me. This is a different bug - and is actually a bug in the source code (part of the Unity3D V4 platform). The result of a collision between the ball and the cup sometimes is sometimes multiplied by -1, causing force to be applied in the direction opposite of what you would expect. According to HB, this is an issue in Unity3D V4 collision physics code, and should be fixed in Unity3D V5, and thus fixed in TGC2. |
