Short description of error

If disable a collection and render opengl using button, the hidden collection is not visible, but running the operator using python, the disable collection is render.

Open attached file
Press opengll render button
Run script and compare results.

After running the script,the collection is visible, but the hidden flag is still disabled in outline and the flag is not working fine anymore. I have noticed that if you save the file and open again, the flag is disabled but the collection is still visisble.

Can you paste the script content here? This way I may be able to help without going to the computer and opening the file.

The script is only this:

import bpy
bpy.ops.render.opengl(write_still=True)

@dfelinto Really, the "real" script is longer and is to help the Hero team with compositing., but I have reduced it to find the line with problems, so you can reproduce the error with this tiny script.

Let me rephrase it, can it be reproduced from scratch?

Antonio Vazquez commented

To reproduce:

Open default
Add new collection
Add suzanne in new collection
Disable collection 1 (with default cube)
Press render opengl button

Now, create the simple script and run it. You will see in the result of script that Cube is not hidden, but in the result of pressing the button, the Cube is hidden as expected.

To reproduce: 1) Open default 2) Add new collection 3) Add suzanne in new collection 4) Disable collection 1 (with default cube) 5) Press render opengl button Now, create the simple script and run it. You will see in the result of script that Cube is not hidden, but in the result of pressing the button, the Cube is hidden as expected.

Confirmed, it feels like OpenGL render via script is making all objects visible doesn't matter what. Looking into it.

@antoniov for now can they delete the view layers they are not using? This should be a workaround until we fix this issue.

@dfelinto I don't think he can delete them.

The script I did is to generate separated images to make composition.

The scene is very complex with a mixture of 3D objects and GP drawings. To make the compositing, each element must be in a separated image (something like renderlayers), but as renderlayers is not working for GP, we need the script or make it all manually.

@pepe-school-land What do you think?

@antoniov change your script to do: bpy.ops.render.opengl('INVOKE_DEFAULT', write_still=True);
The issue I believe has to do with copy-on-write (or the lack of).

I will even close it. This will be fixed once we get copy on write by default (I belive).

@dfelinto Thanks for the idea, I'm going to test.

I think is good idea to close this bug. Really, it's a "ToDo".
