System Information
Operating system: Windows 7
Graphics card: GTX Titan

Blender Version
Broken: blender-2.80-388ff003e28b-win64

Short description of error

I have to do a batch process on many blender files and I need to activate the denoising data in each viewlayer. When I manually activate the Denoising Data button, the python command is bpy.context.scene.denoising_store_passes = True . However it is impossible to retrieive this command from the python console as I get this error message :

Traceback (most recent call last):
  File "<blender_console>", line 1, in <module>
AttributeError: 'Scene' object has no attribute 'denoising_store_passes'

Also, as this is an option per View Layer, this command should be accessible from the same data like other passes, something like :

bpy.context.scene.view_layers["Perso"].use_denoising_data = True

Thanks a lot,

Henri

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Shouldn't the command be bpy.context.view_layer.cycles.denoising_store_passes?

Shouldn't the command be `bpy.context.view_layer.cycles.denoising_store_passes`?

Hello Jacques,

Thanks for your answer. You are right, it is the right command and it works !Thanks. However, the command displayed on screen is wrong :

Thanks a lot for your help.

Did this ever work correctly?

I don't know how that path is computed, yet..

I don't think it ever worked, see #25746 (Adding keyframes to nested custom properties (IDProperties) of a bone fails) and rna_path_from_ID_to_idpgroup.

To solve this we'd need to add an iterator over all ID props in an ID, or a much deeper design change.

Can we determine at runtime whether a certain path is correct or not? We should at least not show wrong data paths...

Right, that should be possible. Not sure why it even finds a path now.
