Description

This project collects relatively easy tasks for new developers to get involved. The tasks for this project are all features that we would accept in Blender releases.

How to Start

  • Browse Quick Hacks to find one.
  • When you want to start working on a task, you can comment on the task to ask for more information if needed.
  • When you have a patch ready, you may assign the task to yourself and submit the diff to get it reviewed.

Please: Verify that there isn't already a patch for the task by somebody else. If that's the case, it'll usually be mentioned in a comment or the task has a (open) differential revision assigned (those are usually listed in the task details, like in T45230)

You may also want to look at the Todo wiki page.

Adding Tasks

Quick Hacks can be added by developers and module team members for functionality that they would accept in Blender. This is not a wish list to suggest features.

Projects must be...

  • Easy enough for an experienced developer to do in a short time (about 30min - 2hrs).
  • Real projects (not simply exercises or janitor work).
  • Acceptable to be added into Blenders code-base without discussion on controversial topics.

No work has been done on this task for quite a long time.
I would like to try and fix it.

Ok I have a preliminary diff working on edge direction and length select (see D5108). It adds on to @matc (matc)'s D4792. I would love to get feedback on this diff!

Gset is just the equivalent to a set in C++ or Java. You can find the implementation in BLI_ghash.c by looking for the BLI_gset_ prefix.

Ahh finally I have some time to work on this! I've implemented @matc (matc)'s patch (D4792) as well as adding the Shift-G keybind for consistency (turned out to be very simple once I figured out how the keymaps worked). Unfortunately, I don't have enough Blender internal/general knowledge to know the inner workings of kdtrees, gsets, etc... does anyone have any pointers on how to extend D4792 to edge and vertex select?

David Hampton (david01) added a comment to T51289: Particle System UI issue/annoyance: setting Start later than End should increase End if necessary, rather than capping it.

This is my first time contributing. I noticed we are not setting a clamp to this like we do for timeline (see "rna_scene.c" lines 881 and 891 for functions called "rna_Scene_end_frame_set" and "rna_Scene_start_frame_set").

Cool, thanks! I have used blender for a while and know C++, but I am new to blender development - any pointers on how to do this? Mostly I am having trouble navigating the rather large codebase, so any advice would be greatly appreciated.

Kelly Dodson (djkellyd) added a comment to T44834: Bone selection icon could be added next to Face and Vertex Selection in Weight Paint mode.

@William Reynish (billreynish) I think I developed a solution. When in Weight Paint mode, clicking the bone icon in the toolbar switches the mode to Object mode (which enables the user to add/edit bones). Likewise, clicking the Weight Paint icon in the toolbar when in Object mode switches the mode to Weight Paint mode. Should I go ahead and submit a patch for review?

@Brecht Van Lommel (brecht) I was able to work on implementing some backwards compatibility logic in version_update.py and now I need to work on integrating the above changes into Eevee, as you had mentioned. Where would I start to look into making changes for Eevee?
