Hmmm. I may have made a mistake by combining two changes here. The first fix for the AABB -1,-1,-1 works. The is_inside() check is not working. I'm still hitting cases where the incorrect LOD is used when the bounds are too large or I'm inside them. And it's very dependent on camera angle. so there's something wrong with the math here that I'm not understanding. |
Fixes bug where bounding box of 1 unit was used in some skinned models and had wrong LODs. (this could become very large if the mesh is scaled, such as FBX conversions) Also fixes a mistake in calcualting bone index.

malcomnixon reported some weird LOD issues with addons/godot-xr-tools/hands/scenes/lowpoly/left_hand_low.tscn from GodotVR/godot-xr-tools, so I'm testing this right now. For now I have split it off so this just fixes the -1,-1,-1 bounding box size which we already tested. And if I figure out the other issue, I'll make a separate PR for it. |

Thanks! |

Cherry-picked for 4.0.4. While this is not a complete fix, code improvement seems good to me to include. |

Use LOD distance of 0 if camera is inside mesh bounds, rather than distance to surface.Also fixes a mistake in calculating bone index.

It might address part of #76436 but I have not tested MultiMesh
