Amazing, you are very creative! Are the extensions you used—like the cartoon shader effect and placing text directly in the 3D scene above objects, like you did with the board—available publicly, or are they custom extensions you made yourself?
Thanks!
The outline effect is done in Blender, using a Solidify modifier with flipped normals, then exported like that no custom shaders needed in GDevelop.
The text on the board uses a public GDevelop extension called 3D Text, which lets you place text directly inside the 3D scene.
Everything used is publicly available no custom extensions are used.
