Blender 2.8, Python Cube Scaling
Blender 2.8, Python. It is said that the cube has been tilted and scaled. When I tilted it into a thin shape, it looked like a smartphone. So far, we have achieved cube placement, material allocation, camera movement and lighting movement. (Future issues include camera angle, gaze at specific coordinates of the camera, movement along the path when moving an object, etc.)
