To texture a 3D model in Godot, import your model, create a Material (e.g., SpatialMaterial for basics or ShaderMaterial for custom effects), assign texture files (albedo for base color, normal for surface depth) to the material’s properties, then apply it to the model’s mesh instance.
SpatialMaterial is ideal for simple needs—add color or shine without code. ShaderMaterial lets you use custom shaders for complex effects like reflections or transparency.
Beginners should start with SpatialMaterial: Drag a texture into its “Albedo” field, then drop the material onto your model in the 3D view to see results instantly.
