**Reducing .blend file size**

Blender can reduce the size of a .blend file using compression techniques. This can be achieved when saving the file by enabling the gear icon on the right side and ticking the Compress option.

**Additional Questions**

Q) Is Python supported<br>

1. No, for security reasons all python is disabled, it's advised to bake out your keyframes, you can use blenders bake action .

Sometimes you may use an add-on or create a scripted expression to drive animation channels, unfortunately, the Render Network disables all scripts, but here's a workaround using the **Bake Action** method
