Would it be possible

Coding Python Support
1

For a python script to be able to specify only specific frames to render.
ie; instead of 1-500, tell it to render 3, 17, 98, 176, etc…
I would rather not use a render farm for just this one project, but I don’t want to do it manually either.

not possible.

it’s actually not very hard… you can set the frame in context, then render!

Updated the script:

  • You can include ranges using “:” or “-”
  • Basic error checking
  • Deleted bunch of useless code >.<
