i’m running an old version of blender and i know a new version has come out so before i install it i want to check a few things:
will installing the new version autometically remove my current version or will they coexist on my system until i uninstall one?
will opening a file with the new version cause it to be unreadable by the old version?
are there problems with how older files(using blender internal, texture mapping, rigging, animation, lighting and constraints) will open in the new version?
can files made in the new version be exported “backwards” into the old version?
is blender internal still supported in the new version, have any other features been lost?
thanks
Assuming you install by just copying over Blender, only if you overwrite the old version. Not sure what behavior installers have
Generally no, but depends on how “old” we are talking. 2.49 and below will have problems reading files saved by 2.5+ versions. The file will load, but some things (like animations) won’t be loaded.
Generally no
Again, depends on how old. 2.63+ will open files without issues, aside from new feature being ignored. Pre-2.63 stored meshes differently, and requires the ‘legacy mesh format’ option to be enabled when saving. Pre-2.5 has the mesh caveat, plus it won’t load animations either. Not sure how gracefully it loads newer feature either.
Yes. BI is still supported.
In short, it really depends on how old of a version you are coming from.
