I want to save the location of a child object during the parent's animation. My code populates the list with the last read value and none of the other values. If I print the z location each iteration with the below I can see the correct value at each frame. I don't understand why the list doesn't save individual vectors.

print(f'Z_Loc: {obj.matrix_world.translation[2]}')

enter image description here

import bpy
obj = bpy.data.objects["Cube.001"]
start_frame =  20
translations = []

for frame in range(2):
    start_frame += 1

for num, ob in enumerate(translations):
    print(f'num: {num} matrix: {ob}')

This gave the result I wanted.

  • $\begingroup$ No need to re reference : translations.append(obj.matrix_world.translation.copy()) $\endgroup$
