Blender(2.8) to After Effects Exporter

Hello everyone,

I’m looking for a working Blender(2.8) to After Effects Exporter.

This one exports everything, but unfortunately all Blender rectangles arrive in After Effects as squares. Besides, they’re in the wrong position.

# ZOOM VALUE CALCULATIONS:
#
# Given values:
#     - sensor width (camera.data.sensor_width)
#     - sensor height (camera.data.sensor_height)
#     - sensor fit (camera.data.sensor_fit)
#     - lens (blender's lens in mm)
#     - width (width of the composition/scene in pixels)
#     - height (height of the composition/scene in pixels)
#     - PAR (pixel aspect ratio)
#
# Calculations are made using sensor's size and scene/comp dimension (width or height).
# If camera.sensor_fit is set to 'AUTO' or 'HORIZONTAL' - sensor = camera.data.sensor_width, dimension = width.
# If camera.sensor_fit is set to 'VERTICAL' - sensor = camera.data.sensor_height, dimension = height
#
# zoom can be calculated using simple proportions.

Does anyone have an working exporter that is a little more current?

I was hoping this would be updated also, I sent a tweet to the author but had no response, I hope somebody capable picks up on this in time for 2.8 release, I find it super handy.

hi, could you please test the version here: https://developer.blender.org/T63856
let us know how it goes either here or in the main task.
Thanks

Hi Meta-Androcto,

great that someone took care of the script.
Unfortunately there is no difference to the old version.
Only 25 out of 100 images are imported.
The position and aspect ratio of the rectangles are wrong.

Blender from today (e80cbdac331a-windows64)
After Effects CS5


Here are the parts:
BlenderToAE-Project-ExportScript-MP4.7z (1.3 MB)

Edit:
I forgot the Blender file.
Blender-to-AE-2.8.7z (224.1 KB)

io_export_after_effects_Blender_2_8.py (37.3 KB)

I changed the version from 2.79. Works well - rectangles are out of place. Checked in CS6

It got a little better.
In your version, all 100 “images” are imported (and not just 25).

This isn’t working for scene with tracking data (if there is a Camera solver applied to camera).

The Error messagge looks like this: https://i.imgur.com/ZL9rh5p.png

This error is from using the old matrix multiplication syntax. There also was some outdated syntax for handling light sources (the term “lamp” was replaced by “light” in the API for 2.80). I fixed those two issues in the addons-contrib-repo, but to make things simpler I have also attached an updated version below (v0.0.66):
io_export_after_effects_v_0_0_66.zip (7.5 KB).

Thank you!

There used to be a scene scale field on the exporter but that appears to be missing from this version?

I always found that handy if I was dealing with other peoples scenes of incorrect world scale.

Could anyone reinstate that in a future update?
