Godot Gridmap: ALL you need to master 3D Tilemaps

Tilemaps are really popular in Godot, and we usually start searching terms like 3D Tilemaps when starting our first 3D game... The exact term is Gridmap which is a really good node to build 3D environments in Godot 4.

But every starting point has some sharp edges that can be really painful. This video will cover all the issues I faced during my discovery of the Gridmap node. How to solve misalignments, displacements and rotations when using mesh libraries on Gridmaps.

Hope this video helps you in your game!

Maybe you are up to applying this new knowledge to a game, check the different tutorials made in the channel:

If you are still alive,
I just wanted to thank you,
I spent days trying to make my whole scene local then gave up on the idea after so many failed attempt with plugins and editor scripts,
then I watch your video just for fun and there it is simple a short, I look at of the window and question the meaning of life
Thanks and I wish you a good and happy life

You have some of the best tutorials on YouTube.

Making slopes in the way you're doing by translating vertices along the vertical axis is a type of common transform called a shear, which it seems like Blender supports. It might be worth looking into since it would probably simplify your workflow and help better support complex objects..

I recommend making your own level editor and just use gridmap as a backend and also use it for placing props and whatever else you need. It is an ok amount of work to do so, (draw a grid with a linemesh, check where the ray from your crosshair intersects with the plane of the moment), more flexible, you get an ingame level editor and can have a good interface tailored to your specific needs. IMHO engines make for terrible level editors and making one yourself is part of game creation if you want good productivity.

psychotic editing, this is exactly how all tutorials should be presented.

I dread using gridmaps but this help a bit!

Non game developer trying to learn here, but it sounds like everyone is frustrated and confused with grid maps because creators tend to publish universal asset packs?? So if I buy an asset pack and want it to work in Godot sometimes I might need to open up 3D modelling software like Blender to make a few tweaks? Trying to make sure I follow the gist.

Although the video was very annoying.... Learned a few things out of it.

All tutorials are boring for me but I loved this one

[generrosity]

Gamesfromscratch just showed off a bender variant with different command layout - i would if that would be easier?

Great overview! Things to now try

[notmyopinion]

I used the same package as you did but my meshes can not be used in the scene. They are literally just blue boxes...

[leoh]

Is it possible to include Area3D nodes into the base tiles, so that when you place tiles, you place all the functionality thats included?

For example, I have a mesh library made up of floor tile scenes.
All of them are basic:
Node3D
->Node3D_Name
-->MeshInstance3D
--->StaticBody3D


However, I have one that is:
Node3D
->Node3D_Name
-->MeshInstance3D
--->StaticBody3D

->Area3d
-->CollisionShape3D

When I place this special tile with the Area3D included, the Area3D Collisionshape doesn't show up on the Gridmap.

Is there a way to include this? Or do I have to manually place the area3D's separately to my gridmap?

I know you put a lot of work into this tutorial but holy shit, those fast cuts? My head is spinning and I barely understood one third of what you were showing. And I know godot and blender. :D

congrats on the most erratic, hectic and distracting tutorial bg music 2024. both it's percussion being high pitch and so clicky goes especially well to interrupt human voices' mid-high frequency spectrum. who'd want to focus on discernible information when you can have totally undiscernible, but still loudly distracting bg music. :P
