blender-colab's Introduction

blender-colab

This is a Python script that allows you to render Blender 3.0+ and older version scene using Google Colaboratory. You can upload the blender files using direct upload, Google Drive or URL. Rendered frames can be downloaded directly or through Google Drive. This script provides basic functionality so you may modify the script to your liking to suit your needs.

Usage

Upload type

direct: Upload your blender file in the next cell.
google_drive: The blender file will be downloaded directly from Google Drive. You need to specify the path to the blender/zip file at drive_path.
url: Direct link to the blender file in url_blend.
gdrive_relative: The Google Drive folder specified at drive_path will be copied directly (as if it's a zipped file).

Download type

direct: Output files will be automatically downloaded in your browser. (Probably does not work with multiple files?)
google_drive: The output files will be pasted into the specified drive_output_path once rendering is finished.
gdrive_relative: The output frames will be automatically rendered into the specified drive_output_path.

A few notes

You must own a Google account.
One notebook can only run for maximum time of 12 hours (24 hours for Google Colab Pro) but not guaranteed.
EEVEE rendering is not supported in a virtual machine.
This script is not tested fully yet. Expect some errors.
Do note that your access to GPU may be limited or blocked if you render for many hours.
This script is intended for those who have no access to high-end GPU for rendering. Please use them responsibly!

FAQ

An error occured!

Check which section of the code failed and identify the error (such as misspelled files or path). If you don't understand the error, try re-running the code with the play button at the side. If it still fails, go to Runtime > Restart and run all to restart the code or try Runtime > Factory reset runtime. If all else fails, open an issue in GitHub with the error log you encountered attached and the details of your setup.

Common errors:

MessageError: TypeError: Failed to fetch while downloading: The tab must be opened so that the frames can be downloaded.

Disclaimer

Google Colab is targeted to researchers and students to run AI/ML tasks, data analysis and education, not rendering 3D scenes. Because the computing power provided are free, the usage limits, idle timeouts and speed of the rendering may varies time by time. Colab Pro and Colab Pro+ are available for those who wanted to have more powerful GPU and longer runtimes for rendering. See the FAQ for more info. In some cases, it might be faster to use an online Blender renderfarm.

blender-colab's Issues

Need help!!!, I'm creating code for baking textures, there is code but it doesn't work as expected

I made a code that bakes textures in Google colab

import os # Import module os

blender_url_dict = {'4.0.2': "https://ftp.nluug.nl/pub/graphics/blender/release/Blender4.0/blender-4.0.2-linux-x64.tar.xz"}
blender_version = '4.0.2'
blender_url = blender_url_dict[blender_version]
base_url = os.path.basename(blender_url) #Use the module os to access the function basename
!mkdir $blender_version
!wget -nc $blender_url
!tar -xkf $base_url -C ./$blender_version --strip-components=1

import shutil
from google.colab import files, drive
uploaded_filename = ""

!pip install bpy

import bpy

Finding the file path .blend

Folder selection

folder_path = "" #@param {type: 'string'}

Entering a file name

file_name = "" #@param {type: 'string'}

Forming the path to the file.blend

blend_file_path = f"/content/drive/MyDrive/{folder_path}/{file_name}"

Loading an existing .blend file

bpy.ops.wm.open_mainfile(filepath=blend_file_path)

Setting your preferred rendering devices(GPU и OptiX)

prefs = bpy.context.preferences
cprefs = prefs.addons['cycles'].preferences

Setting up GPU rendering and activating devices

for compute_device_type in ('CUDA', 'OPTIX'):
try:
cprefs.compute_device_type = compute_device_type
print('Device found:', compute_device_type)
break
except TypeError:
pass

for device in cprefs.devices:
if device.type == 'CUDA' or device.type == 'OPTIX':
print('Activating', device)
device.use = True

Starting the baking process

bpy.ops.object.bake(type='DIFFUSE')

Entering an image title

image_name = "No name" #@param {type: 'string'}

Forming a string to search for an image

image_object = bpy.data.images.get(image_name)

Checking that the image exists

if image_object:
# Saving an image in PNG format
image_object.file_format = 'PNG'

# Entering the name of the baked texture
Baked_image_name = "Baked texture" #@param {type: 'string'}

# Forming a path for saving an image
image_object.save_render(filepath=f"/content/drive/MyDrive/D/{Baked_image_name}.png")

else:
print("Image not found")

but it needs to be completed, if you can help me, leave a comment here

wrong things in coding

I found some horrible issues... I fixed it in my fork. here: https://github.com/AstroNaut244/blender-colab

I show you whats wrong in the original. This is the fixed version:

And this is the original:

Error in blender_url = blender_url_dict[blender_version]

Error:
`---------------------------------------------------------------------------
KeyError Traceback (most recent call last)
in ()
9 '2.93.1' : "https://ftp.nluug.nl/pub/graphics/blender/release/Blender2.93/blender-2.93.4-linux-x64.tar.xz"}
10
---> 11 blender_url = blender_url_dict[blender_version]
12 base_url = os.path.basename(blender_url)
13

KeyError: '2.93.4'`

Setup:

UPD. No error occurs if i choose version 2.92.0

can't use texture environment

Before Rendering

After Rendering

how to render with the texture environment?

cannot be preloaded (cannot open shared object file): ignored.

After this;

!rm -r render
!mkdir render

if upload_type == 'gdrive_relative':
if not drive_path.endswith('/'):
drive_path += '/'
!cp -r '/drive/My Drive/{drive_path}.' 'render/'
elif uploaded_filename.lower().endswith('.zip'):
!unzip -o $uploaded_filename -d 'render/'
elif uploaded_filename.lower().endswith('.blend'):
shutil.copy(uploaded_filename, 'render/')
blend_file_path = uploaded_filename
else:
raise SystemExit("Invalid file extension, only .blend and .zip can be uploaded.")

I GET THIS FOR A SINGLE CUBE BLEND FILE

ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libtcmalloc_minimal.so.4.3.0' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

Error

When downloading a file directly from a PC, a bin bash error is generated, which says that the file or directory is missing, this did not happen before, the files are not corrupted, I even changed the blender version to the newest one (was 3.0.1)

Feature Request: Add add-on support

extra attributes

is there an attribute we can use to enable ray tracing, like how we use -s to specify the starting frame, is there any attribute we can use to decide whether ray tracing should be enabled or not?

I cant upload the file, i need some assistance.

SystemExit: Invalid file extension, only .blend and .zip can be uploaded.

Feature Request: Add drivers support

Hi! first of all, thank you for your work that helps many people
It would really helpful if you could add option to turn disable/enable auto scripts execution option on blender launch so we can use drivers in scenes :)

Reduce render samples?

Great little tool, thank you!

When rendering it defaults to 510 tiles, when I want to sample only 64. Is that possible?

2.9.x

This would be great if it supported those

Rendering not working

I was able to upload my own video
However, an error message was output from the third code paragraph, "rm: cannot remove 'render': No such file or directory"
But I ignored it and executed the 9th code, and Blender 3.0 was installed well.
I thought it went well because the fifth paragraph didn't print anything out.
The 6th paragraph was filled with error codes below.
What is wrong with this?
first what is the error "rm: cannot remove 'render': No such file or directory"
and what should i do?

Any solution?

Failed to create OptiX denoiser

Refer to the Cycles GPU rendering documentation for possible solutions:
https://docs.blender.org/manual/en/latest/render/cycles/gpu_rendering.html

E1216 11:29:07.508268 1742 denoiser_gpu.cpp:119] GPU denoiser creation has failed.

This was working all well last week however, it's now bugged.

I'm using T4
