@MasterHelix9

Just add it before this(the invoking of the render):

!sudo ./$blender_version/blender -P './setgpu.py' -b '/gdrive/My Drive/{path_to_blend}' -E CYCLES -o '/gdrive/My Drive/{output_path}' -a

And remember to replace CYCLES with BLENDER_EEVEE in the above.

Thank you for your help!

Is it possible to change active camera and scene while rendering?

Absolutely. You just need to extend the the quoted python script and select programmatically the camera and scene you prefer

Absolutely. You just need to extend the the quoted python script and select programmatically the camera and scene you prefer

@donmahallem What's the code to do that?

@MasterHelix9 I would refer you to google, stack overflow and the current Blender Api Documentation.

It all depends on what you are trying to accomplish. Otherwise you would have to do that manually by rendering just the frames you need and switch out the file

@donamhallem I have multiple cameras in my scene and they should render same frames but from different angles, so I need a way to switch between cameras inside google colab without having to change active camera in project file and reuploading it again every time. I found a command that can do that: bpy.context.scene.camera = bpy.data.objects["camera_name"] Do I need to import or install any extra modules to google colab for this to work?

The only other way I see is switching the camera of the scene as described above or create multiple linked scenes with a camera for each one.

Imho: it's easier just to reupload the changed active camera imho and render everything twice as you multiply the render time anyway with the camera count.

@donmahallem If I want to use this command: bpy.context.scene.camera = bpy.data.objects["camera_name"] do I need to install/import any extra modules (bpy) to the google colab?

Afaik no.

For reference you can use the documentation linked above where you can look up available interfaces for any given blender version and which instructions to use.

In the gist above there is a section which uses and launches a small python script as well.

I am currently only on the phone and can only give coarse directions where you need to look. Try the script locally for switching the cams. Either embed it into the blend file(might be prone to issues) or queue it after the blend file loading with a '-P' cli argument.

From what I understood you want to do the easiest imho is still to render all frames for one camera. Switch active camera and render all frames again

it didn't work just says ### there is no such file or directory

Please read the error message carefully.

Error: File format is not supported in file '/gdrive/My Drive/Blender_colabrender/magingrass.blend'

Are you sure your blend file is correct?

Yes man. I know you are thinking about "makinggrass" spelling but it is actually the same name I gave to my blend file

As the error clearly states: blender can find the file but blender can't read it. I can't tell from here what is wrong with the file

I think maybe the size is a problem as it render normally if I don't increase sub-division or add HDRI. Well here is my Rendered result: https://drive.google.com/file/d/1-TP1894jYfF8WcJH6RTYG9Ji3n1Fw1ri/view?usp=sharing

How I can include the path to bake file in the drive, is there any specific keyword for that?

Put all files into one folder on your local drive. Make all paths relative with blender, save and upload that folder. this way your paths to external files should be platform independant

Will see it in while.Thanks for the quick response :)

i have revised it a bit for my own research purpose. can I make it public in Github (just want to get permission from you first).
really appreciate it!

@donmahallem

@nanlliu if you have any improvements you are free to share them. This gist is an auto update of this repository. If you have any improvements you are invited to provide them as a Pull Request and contribute to the project.

i didn't improve anything and it doesn't fulfill the same needs. it runs a program that uses blender. It is a program that generates a bunch of dataset called 'Clevr'.

I tried to render in GPU new cycles x in Google Colab, but I can't, this message showed (some suggestions):

• Maybe I have to try the paid version of Colab to avoid queues?

I notice that there are some redundant files gitfile1.txt, gistfile2.txt etc.

That is because exuanbo/[email protected] introduces a bug causing the gist filename to be un empty string if gist_file_name is not provided. It is fixed in v1.1.2 and v1.

@exuanbo Thanks for the info. Will try to clean this up asap
