I'm now using blender 2.79b. So the problem is, if I change the version from blender 2.79 to blender 2.8, is all of my work in blender 2.79 lost?

  • $\begingroup$ If you are refering to opening 2.8-files in 2.79, then yes, you can't open 2.8-files in 2.79. You have to continue working on them in 2.8. You can try to export individual components through obj / fbx export though. $\endgroup$ – Leander Dec 25 '18 at 0:17

Yes and no... Yes if you have simple blend files, I saw that 2.8 opens them pretty easily. If you re-save them using 2.8, then, yeah you cannot open them in 2.79. Blender will crash.

No, if you have Armatures blend files (I've been using a simple biped rig from the internet, much like 3DS Max has) then you will have issues. Also, I saw that collections tend to disappear from one save to another... (but maybe is because the Armature rig is coming from a 2.7x version...)

  • $\begingroup$ so all of my armature project is dissapear? $\endgroup$ – mr car Dec 24 '18 at 5:57
  • $\begingroup$ Not the Project. Somehow the project was available (with the animation playing well) In 2.79, I had the bones in a different layer so I opened the same scene in 2.8 (since Cycles is 30% faster there). As far as I understood the layers from 2.79 became Collections in 2.8, so when I first opened the Blender 2.80B I had the bones visible all ok, packed in Collections 1. In Collections 2 I had the body of the character plus the other objects. $\endgroup$ – Mihai Dec 24 '18 at 8:45
  • $\begingroup$ After 2h of animation, I saved and restarted the Mac (so it can update Mac os...) and next time I opened Blender 2.80 (the saved scene) the bones were missing. Collection 1 was empty. (I opened many times Blender, redownloaded, restarted MacOs.) So I redo the animation again and call it a day (it was pretty late in the night). Next morning the Collection 1. (with the bones/Armature) was missing altogether. $\endgroup$ – Mihai Dec 24 '18 at 8:45
  • $\begingroup$ If you are unable to open your file you can always try and use the "append" from the file drop down menu to retrieve your data. It seems like that the data bases are still compatible both ways. $\endgroup$ – Sidar Dec 24 '18 at 9:41
