🐛 [Bug Report] Creature or players' pets falls under the ground

[aleigood]

Bug Details

In fact, this problem is often encountered in the game. Not only NPC, but also players' pets will occasionally fall under the ground. In addition, on the ground of Pingdan, rules cannot be found. The possible reasons are similar to this problem, but I'm not sure. ()

Another piece of evidence, to be clear, is not necessarily reproducible. I found this when I verified that a player fed back that a soldier would fall into an underground cave when charging. In fact, the problem is quite common. hope this problem will not be ignored.

doesnt happen for me, this looks more like a camera bug with your client, because as you can see his Z level is perfectly fine, his model just isnt rendered.

This may be the reason, but generally this problem should occur when other buildings or objects collide at the lens location. If no other objects block the lens, will this also happen?

belive or not..blizz has same issues.. last week we fixed this formation: https://github.com/cmangos/wotlk-db/commit/4c6d8b0a3444f29733b1157dac480db70f809d27 and in sniff they were going underground also.. so I had to manualy set 1 wp point to avoid it.

I blame: mmaps, vmaps or pathfinding system... (hard to say what exactly)

Client collision logic between expansions also differs, sometimes a lot (explorations via cliffjumping in vanilla no longer possible in tbc+ and so on).

As it is not happening for me and extracted Data is the root of the issue, why dont we test the Extractiondata i'm using right now to see if it comes to be true Might be different from what default cmangos is using (i had a hard time beliving the new default parameters for extraction process to be good default values myself), but i also dont know the parameters of how they were created, got mine from @killerwife.

And as i said befor, as you can see the hitbox circle this looks to me that it is not a clipping issue, the model just isnt rendered due to angle or due to collusion with the tend behind the player which has somewhere collusion with the camera, because the object size blocks los or what not, but isnt correctly applied to the actual size of the tent (too big).

try maps with "low resolution", sadly "high resolution" does not mean they are better.

edit: we should really think about providing more info on what values to use for extracting default testing data.
