After searching for several hours on that topic now it seems to me like this is a known but unsolved problem. Hoping i’m wrong here comes the description:
I’m working on a script where i animated an object based on input data frame by frame, now i want to have frame-dependent access to the objects’ data from a script.
You can simulate this setting with very little effort by just animating an empty over a few frames (and maybe bake it to have the same setup, see image).
Now consider the following script:
import bpy ob = bpy.data.object # the object we have animated # lets say the animation went from frame 1 to 41 for i in range(1,42): print("Frame "+i) # set frame to i bpy.context.scene.frame_current = i # updating the scene bpy.context.scene.update() print(ob.location)
So here comes the Problem:
Why does scene.update() not really update the scene?
I know there are reasons to not update anything after every little change because of reasons, but i thought (and read*) that scene.update() would to such an update.
I expected to get the location per frame, but the printed locations are all the same.
Any help, hint or link welcomed!
PS: I was trying several combinations of update_tag() but none of them helped.
According to the link tagged data is being updated, maybe im just missing this part?
