What is the main changes and difference between 2.79 and 2.80 version?
Is the difference so big, i mean it is bad to stay on 2.79 version?
Eevee … a semi-realtime render engine is in 2.8 .
Whereas 2.79 still has Blender Internal render engine.
There are other differences, but this is the main one.
Currently, last official stable version of blender is 2.79b. It can’t be a bad thing to stay on last official stable version.
Yes. There are lots of disturbing differences between 2.8 and 2.79.
Shortcuts are not the same. UI does not look the same. Scene management is not the same.
But Tools are almost the same.
Some have been improved. Some have not been restored, yet. Some are buggy. Some have been removed. Some are completely new.
These differences between 2.80(under development) and 2.79 (stable release) are listed on wiki.
A release notes page exist for each blender release since years.
There are always a lot of differences between to previous release and next release.
When comes the step to upgrade to a new series, it is a tradition in blender development to improve the UI.
It means that even Blender users knowing a previous version have to study it to retrieve their marks.
So, that is a very drastic change that only happens after a minimum of 3 years of development.
There was no fundamental change of UI between 2.5, 2.6 and 2.7.
So, 2.8 UI is a move never seen since a decade in that area.
2.8 will not have a game engine like previous version.
The historical render engine have been removed to be replaced by a tremendously faster, almost realtime new one.
Yes. 2.8 is a big event.
If you are interested by Blender , you have to take a look at it.
But that does not mean that you have to use 2.8 at its current beta state or have to learn 3D with a beta software.
