Setup your Render
There are two ways you can upload your Blender project: as a .blend or in a .zip archive.
If you're working with large files like videos and bake caches, you should use a ZIP.
Blend
The easiest way to upload your project is by packing all external files into the .blend:
Important: Not all files can be packed. Large files like videos and bake caches should instead be uploaded in a .zip.
Save the .blend file, then select:
File > External Data > Automatically Pack Into .blend
Save the file again, then it's ready to be uploaded.
ZIP
Include all of your external files in a .zip, along with your .blend file.
Important: All physics simulations need to be baked before you upload.
Folder structure
Place the .blend you want to be rendered in the top-level directory.
For example:
City Render/
|─ City.blend
|─ Files/
| |─ Textures/
| | |─ Brick wall.png
| |─ Videos/
| | |─ Traffic.mp4
| |─ Scenes/
| | |─ Building.blend
City.blend will be rendered in the above project structure.
Blend setup
It's necessary to make all external file paths relative to the .blend file.
In Blender select:
File > External Data > Make All Paths Relative
Then save the file.
ZIP the folder containing your project, then it's ready to be uploaded.
