Frequently user’s post on forums requesting assistance with automating render file naming. Most replies are geared specifically to address the exact request of the original post.
I have put together a small add-on available for free use at https://github.com/Nezumi72/batch_render_helper that includes many common requested functions as well as some flexibility for render file name generation. This is not intended to provide the full range of functionality of a paid add-on but was a 2-3 day project that I felt may be useful to some new user’s of Blender.
Please note I am not a programmer and merely tinker under the hood of Blender’s api. If you notice an issue with the add-on and post the problem on github I will try to correct it but this isn’t intended to become or replace available paid add-ons. As such feature request may or may not be developed though suggestions are welcome.
Cheers,
