Hello, I would like to mak a gridmap for my 3D strategy game, the problem is that my tiles are quite complexe, they are made of multiple meshes with severals material in it and all. It seems that gridmaps can only tiles simple and uniq meshes right ? Is there a way to map my complex map ? can I "simplify" my complex meshes ?

for the exemple : I have a forest tile with several 3D trees themselves made of 5 meshs with 4 materials but I want my forest to be a tile in my game. and I want to be able to place a forest tile next to a grass tile for example.

Any of you know a simple way to achieve that ?

thanks a lot !

Correction, I can merge the meshes in Asset forge at export, but now I can't create a mesh library like in this video : without all my meshes beeing stacked all over each is the gridmap (unlike in the video).

Not sure if can help, i have tried the Gridmap one time by following this tutorial.
I think its goes deeper that the one you have posted, even if old project on godot 3.1.
(As i see most of materials interpolation are made it on Blender before exporting on Godot).

I'm not sure if there is a problem with multiple objects or not. I think if you export them as one object it would work but I haven't tried it yet. Just getting started with them. Otherwise you can combine objects in blender by using control j.
