Gridmaps are a pain to use

I've been trying to set up a grid map to design the main lobby for my game and it's not that anything isn't working as it's supposed to (as far I know) but just that the system of painting the tiles has been unimaginably frustrating for me. I'm using a set of simple 3D planes with a few adjustments for things like curved roads, curbs, and other similar things that I modelled in blender. The first issue arises in the fact that bottom sides of all the faces on the models are invisible when imported in Godot, because that's how models work. That wouldn't be a problem except when I'm trying to paint in the Gridmap and I can't see the tile because its upside down or facing away from me it gets annoying. It's also painfully difficult to tell which direction the tile is rotated, from all angles except when I am looking directly at the top of the model. Trying to get the direction I want for each individual tile has been stupidly difficult and tedious. Not only that but every time I exit out of the paint mode and re-enter, the tile is facing in a seemingly random direction again with no logic or consistency that I've been picking up on. I've been stuck for nearly 3 days trying to get it to work to no avail, and it's been very frustrating and demoralizing since it's halted my progress. Is there any settings or strategies or something to make using the Gridmap not give me an aneurism. I'm even up for outside programs that allow you to design maps in said program and then export to Godot, so long as it's not as pain inducing as Gridmaps have been for me

PizzaHutsAlat For start, disable backface culling on mesh materials so you can see the polygons from both sides.

It's all about how you set up the mesh origin and make sure the scale is always 1,1,1 before export it to Godot. You really need to plan how each mesh is gonna connect based on that "little origin orange dot" in Blender. Here's mine for a 3D sidescroller:

As you can see I purposely offset my meshes origin in Blender so that in Godot they fit perfectly according to Godot grid.

It's hard to explain how to set them up. Try exporting a box with different origin location and you'd see that Godot place them differently on the grid, then work it out from there.

Gowydot I was confused at first but I think I have a very vague, yet still useful idea of how it works and it's not longer as annoying now. I also removed the WorldEnviroment in the scene I'm designing the Gridmap in and the brighter lighting made it a bit easier. Thank you

Took me a while to learn it as well. The tip is to keep origin in the same position but move the whole mesh by its vertices (in Blender's Edit mode, and not the mesh in Object mode). That way when you export to Godot the origin point of connection and rotation is the same for all the meshes.

I end up didn't use Gridmap for my project though, after all my learning. I want more flexibility of those meshes for my level, such as disabling collision, exploding ,... etc, which would be a headache if I were to use Gridmap.
