Operating system: Windows10PRO 64bit v2004 (May 2020)
Graphics card: -
Broken: 2.90.1 "stable release", same behaviour also on 2.90 and 2.91(alpha)
Worked: 2.79b, 2.83.6
Short description of error
Opening an older blend file (2.49) exits Blender 2.90.1, but succeeds in 2.79b.
It can be loaded in Blender 2.90.1 if it was saved again in 2.79b
I got this 3D model in a .blend file. When directly opening it Blender 2.90.1 (official release) exits sliently.
Then I opened that file in Blender 2.79b and saved it to another name; Opening that new file then works in Blender 2.90.1
although some blend files (even from that old version) open properly its not really surprising that older versions may not work anymore;
BUT: Blender should not silently exit; instead there should be a notification, that (or if possile why) the file cannot be loaded.
Especially for the future this is very important, cause when I now save all my assets as .blend files v 2.90.1 on a DVD,
I want to load them properly also in ten years without being required to convert them all! :)
Consitency of the file format should be the key, shouldn't it?
Exact steps for others to reproduce the error
- Try to open black_head_b3d249_1_v5.blend in any 2.9x version of blender
Here a simplified file (geometry + textures removed and replaced by default cube) saved in 2.49:
Here the same file saved in 2.79 (fixed):
