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.

Maybe there is no real overhead from grease pencil and it's just happens to be waiting for the graphics driver there.

Antonio Vazquez (antoniov) added a comment to T70015: Grease pencil slows down vertex painting.

I have been looking at the code and really is not doing anything, it's a group of DRW_TEXTURE_FREE_SAFE and all textures are NULL except one of 1x1 pixel. The problem here is the GPencil engine is enabled when no GPencil objects are in the scene, so the Engine_init, cache init/populate/finish and draw scene, free is called... and this is to do nothing. This uneeded call is creating the passes and a lot of things that we don't need.

@Clément Foucault (fclem) Is making IMM_BUFFER_SIZE stretchable, a better solution or not? I think it fixes this problem very easily with small amount code change.

Hi there. New to Blender Development.
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").
