Frame_set polutes the console

Hi all,

why does the console spit out “post NUMBER NUMBER”?

I was wondering if this can be turned of, i kinda polutes the console for no reason or does it have a reason?

If you test this code, you get a print of all those frames

import bpy
scn = bpy.context.scene
curr = 0
for curr in range(1,25):
    scn.frame_set(curr)

This is the printout from the console then

Im working on an addon which sets the frame to cache mesh data of that frame. I would like to know if there is a method of not showing this. I doubt there is since this is done internally as it seems.

Is there perhaps a better approach to this?

The print seems to come from an application handler you’ve registered, presumably appended to bpy.app.handlers.frame_change_post().

I tried looking but for me default scene also shows it. The issue is on Windows i cant do proper search it doesnt like . in the name.

I doubt its cause by a frame_change_post. I did a search in user addon folder, no results, then tried blender addon folder and get 5 hits. None of these handlers send a print with matches this ie post 10 10

Perhaps on which does pre? Ill try that one as well. Its like finding a needle in a haystack :wink:

EDIT
Nothing for frame_change_pre
So i guess i should go over more handler types right?

I got some options here, i dont know all, but i guess i can filter out a couple of them, they are none-related

'depsgraph_update_post',
'depsgraph_update_pre',
'frame_change_post',
'frame_change_pre',
'load_post',
'load_pre',
'persistent',
'render_post',
'render_pre',
'render_stats',
'render_write'

I might be stating the obvious, but presumably the code generates the string based on the current frame (bpy.context.scene.frame_current) or a counter, so searching for “post 10 10” won’t find any results. If you haven’t already I would search for just the “post” string in the user installed add-ons.

In order to limit the output to relevant results you could try to search for print(f"post and print("post.
