For the 3D objects in our scene, I used Blender assets for the chicken and strawberry, while the rest were created natively in Spline.
This combination method not only saved time in creating the 3D models but also optimized the scene size. Blender assets, such as OBJ or FBX files, often have high polygon counts which can affect loading speed.
So combining them with lightweight Spline-native models ensured better performance.
