If this: Thrive in Godot tech test runs for you, then yes.
It is 3D, just like before. Thrive hasn’t used 2D rendering for the cell stage at any point.
We are almost done with having all of the Thrive graphics in Godot, and so far there hasn’t been any missing features. I’ve heard that Godot has really good 2D, better than even unreal and unity, so perhaps compared to that the 3D in Godot is nothing special.
