Blender legacy

Keeping Blender 2.79b up-to-date with modern compiler and libs, stability/security/performance -improvements are also welcome.

Start point:

• https://download.blender.org/source/blender-2.79b.tar.gz
• https://web.archive.org/web/20230405025010/https://download.blender.org/source/blender-2.79b.tar.gz

Why

• On older hardware (2008 era) Blender 2.79b runs much smoother (or even at all) then newer versions.
• When you prefer the old GUI over the new one.
• When you don't need all those fancy new features Blender >=2.8 has.

Progress

Progress is tracked on the testing branch.

Libs

Library	Version	Builds	Comment
FFmpeg	6.1	Yes	Needs testing, but it builds.
Python	3.11	Yes
Python	3.12	Yes
OpenCollada	1.6.68	Yes
OpenColorIO	2.2	No	For now use OpenColorIO 1.1 or build
			with WITH_OPENCOLORIO=OFF.
OpenEXR	3.2.4	Yes
OpenImageIO	2.5.10	Yes
OpenVDB	11	Yes

Compiler

Issues

• With Intel HD graphics (using crocus_dri.so), Blender will crash when selecting an object. Setting Selection to OpenGL Occlusion Queries under User Preferences -> System will resolve this. See https://projects.blender.org/blender/blender/issues/52527

• Most addons needs update to recent Python, only some have been updated and are working again. This shouldn't be to hard of a task, but I simply don't have the time to test every single addon there is and only test/update what I use. Please report non working addons so we can fix them together.

• This currently only compiles without CUDA support. I'm not working on this issue, but a patch is welcome.
