Final Report

The GSOC coding period has officially come to an end as of this week and I have posted my final report over on the wiki. I apologise for the lack of a report last week, I spent the entire week working on a foundation for better multi-object edit mode and decided it was best to wait for more feedback about the build that I posted before making a report.

This report contains a list of various bug fixes and additions I have made as a result of feedback about last week’s build as well as a new build for testing. I will also discuss the plan going forward.

End of Coding Period

Now that the official coding period has come to an end I will no longer be implementing any new features. My plan now is to spend some more time fixing any further bugs / minor improvements given as feedback about the latest build. I am going away on holidays this upcoming week and so will be slow to respond until after I return.

I will also discuss further with my mentor about continuing work on a better multi-object edit mode as well as beginning the process of merging my changes into master.

New Build

The new build of my branch soc-2021-knife-tools is now available on: Blender Builds - blender.org

Patch notes since the previous build are outlined below and once again I would appreciate it if you shared any feedback you may have about this latest build on my feedback thread.
