Hello, constraint_orientation and proportional are changed to orient_type and use_proportional_edit from TRANSFORM_OT_translate in Blender 2.8 right? Strangely, after I changed the code, Blender 2.8 keeps crashing with Exception_access_violation error while Blender 2.79 version works fine.

error: Exception_access_violation
address: 0x00007FF615C3CE8
module: C:\Users\junew\Desktop\blender-2.80rc3-windows64\blender_2_80.exe

Here’s the new code:

    override, OBJECT_OT_duplicate={"linked":False, "mode":'TRANSLATION'}, 
    TRANSFORM_OT_translate={"value":(0, 0, 0), 
    "constraint_axis":(False, False, False), 
    "orient_type":'GLOBAL', "mirror":False, 
    "use_proportional_edit":False, "proportional_edit_falloff":'SMOOTH', 
    "proportional_size":1, "snap":False, "snap_target":'CLOSEST', 
    "snap_point":(0, 0, 0), "snap_align":False, "snap_normal":(0, 0, 0), 
    "gpencil_strokes":False, "texture_space":False, "remove_on_cancel":False, 
    "release_confirm":False, "use_accurate":False})

Any idea why? Here’s the complete script.

You seem to be testing this with a pre-release version of Blender 2.80 (release candidate 3), which has reached its end of life a while ago. The current Blender versions are 2.92.0, 2.83.13 TLS and 2.93.0 Alpha (currently under development). Please test if this is an issue in the current versions. If correct usage of the API results in a crash, report it as a bug. This guide might be of use. Try to create a minimal example script that can be posted directly on the bug tracker.

The link you’ve posted doesn’t lead to Python script but a .7z with textures and a project file, named test_round4.7z.
