"Apply as Rest Pose" fails in Blender 4.0+ #649

Open loriducci opened 1 year ago

loriducci commented 1 year ago

Currently using the development version of Cats from here with Blender 4.0.1, this same operation works on 3.6.2.

To reproduce: Enter pose mode>Deform armature>Apply as Rest Pose

Gives the following error:

bpy.ops.cats_manual.pose_to_rest()

Python: Traceback (most recent call last): File "C:\Users\lxadmin\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\cats-blender-plugin-development\tools\armature_manual.py", line 383, in execute PoseToRest.apply_armature_to_mesh_with_no_shape_keys(armature_obj, mesh_obj) File "C:\Users\lxadmin\AppData\Roaming\Blender Foundation\Blender\4.0\scripts\addons\cats-blender-plugin-development\tools\armature_manual.py", line 414, in apply_armature_to_mesh_with_no_shape_keys bpy.ops.object.modifier_move_to_index(context_override, modifier=mod_name, index=0) File "C:\Program Files\Blender Foundation\Blender 4.0\4.0\scripts\modules\bpy\ops.py", line 106, in __call__ C_exec, C_undo = _BPyOpsSubModOp._parse_args(args) File "C:\Program Files\Blender Foundation\Blender 4.0\4.0\scripts\modules\bpy\ops.py", line 60, in _parse_args raise ValueError("1-2 args execution context is supported") ValueError: 1-2 args execution context is supported

This is because of some big changes in 4.0 which breaks alot of plugins due to api changes.

I would not count on cats getting updated for 4.0 as the project seems mainly abandoned and quite a few things won't work as well due to MMD Tools not being updated to 4.0 as well.

However there is a pull request which does seem to fix the issue for pose mode https://github.com/absolute-quantum/cats-blender-plugin/pull/648

I have a version I edited which has this functionality working. Possibly thinking of making a fork and letting people use it!

This is a VERY hackey fix, but I cloned the CATS repo into my blender addons dir and checked out the #648 branch. Blender happily enabled the custom addon and that branch fixes the "Apply as Rest Pose" feature.

I've also fixed this issue in my fork of the project https://github.com/OneLegitDev/cats-blender-plugin-4.0 as well as a few other fixes.

The branch by @Yusarina also includes a fix for this and I've been using it successfully in 4.0+ Thanks everyone! https://github.com/Yusarina/Cats-Blender-Plugin-Unofficial-
