Gridmap:

• [x] Cannot create a MeshLibrary for GridMap, either using ArrayMesh or procedural meshes #10118 (bug)
• [x] GridMap does not work #9111 (bug)
• [x] Cannot edit grids in the 3D viewport #10395 (bug)
• [x] GridMap always visible even when set not visible #907 (bug)
• [x] Add a get_used_cells() method like in TileMap #11857 (enhancement)
• [x] Gridmap editor doesn't respects cell scale #10128 (bug)
• [x] Duplication of tiles is broken in Gridmap #8812 (bug)
• [x] Crash when Octant size is set to 0 #6515 (bug)
• [x] Include transforms of tile object's children when generating .meshlib file #11722 (bug)
• [x] GridMap does not convert collision data and it's not possible to define this data manually #11888 (bug)
• [x] Freelook mode does not play well with Gridmap editor #10697 (bug/enhancement)
• [x] Wrong UV mapping when atlasing enabled for 3D objects #6207 (enhancement)
• [x] Pick up tile from map #3829 (enhancement)
• [ ] Collision section of GridMap is outdated when compared to TileMap, (No collision Layers) #3284 (enhancement)
• [x] Convert an arbitrary point in world space, to GridMap cell coordinates #11856 (enhancement)
• [ ] A signal or callback for on_cell_changed() #11855 (enhancement)

More wide ones:

• [ ] Node Concepts for Module: Grid2D, Grid3D, HexGrid2D, HexGrid3D #10005 (discussion, feature request)

Postponed to 3.1:

• [ ] More obvious way to rotate GridMap tiles #6639 (enhancement)
• [ ] Hide tiles when mouse hovering over them (to give ability to see how gridmap will look like after placing new tile) #5526 (enhancement)

_(fell free to propose related issues, but note that I will moderate this thread in case of off-topics)_

I've also been having issues adding collisions to the gridmap. It doesn't import any shapes and it does not let you change the number of shapes, in the shapes array, so I cannot add them manually.

[reduz]

@Giacom That seems to work correctly now

[Giacom]

Still having the same issue. Collision shapes aren't being imported and I can't manually change the shapes array, trying to resize it immediately puts it back to 0.

I'm on the current master branch, from when this post was made.

@Giacom this deserves it's own issue. Please open new one, include detailed reproduction steps and sample project. Thank you

907 is done, too.

[pwab]

10697 and #11856 were fixed.

[saranvdev]

About More obvious way to rotate GridMap tiles I think the current rotating is okay, but we need one more thing - flipping tiles, along with rotating.

[EzraT]

18836 should probably also be added to this.

[Toshiwoz]

17118 probably should be part of this tracker.

[aaronfranke]

22205 too, as Vector3i would be very useful for GridMap.

[Xenoamor]

Has there been any discussion about mirroring items in the GridMap? Is there enough free data in the structure for this, I imagine we'd only need a few bits

See #31340

[qarlosh]

If the parent or some ancestor of a GridMap has visible = false, the GridMapis still shown. It only hides when setting its own visibleproperty to false. Maybe this is related to #907 .
