Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Blender Version
Broken: blender-3.2.0-alpha+master.bf80dc2bd4ac
Worked: 3.1
Short description of error
In the new OBJ importer, the material blend mode for Eevee is set to "Alpha Blend" if a there's an alpha texture (map_d), but not if there's an alpha factor (d) with a suitable "illum" mode. The old importer sets it correctly.
Exact steps for others to reproduce the error
Import an MTL material with a
d 0.5line but nomap_dline, and illum value of 9.Added subscriber: @scurest
Changed status from 'Needs Triage' to: 'Confirmed'
OBJ/MTL import: opaque blend mode for d<1to OBJ/MTL import: new 3.2 importer does not set blend mode for d<1Added subscriber: @lichtwerk
Marking as High prio since it is a regression from the old importer
OBJ/MTL import: new 3.2 importer does not set blend mode for d<1to Regression: OBJ/MTL import: new 3.2 importer does not set blend mode for d<1This issue was referenced by

Since this switched to focus on the illum regression, I've refiled the original d<1 issue as #97743.
