(Blender) Applying the current pose as rest pose on a model with shapekeys?

[ficool2]

I posed a ported model, which has flexes, as close as I could to a TF2 character, but the issue now is I can't set its rest/reference post to be this current pose.
Trying to Apply Pose as Rest Pose fails as the mesh doesn't update to the new pose.

Trying to apply the Armature modifier in an attempt to fix the above issue also fails due to this error:

Is there any workaround I can do (such as a plugin)? I must keep the shapekeys, so deleting them is not an option. Seperating the head is also not an option as I have adjusted the head/spine bones.

Ehh. No, won't work right now. You can't transform shapekey vertex locations with bones yet. I mean it's not that hard. Just gotta transform the bone first and then figure out the relative morph location, but that's just me thinking... it's probably harder to code for the devs. Chill. Wait for it.

Bump, I still really need a workaround for this since I don't want to learn 3DSmax solely for this

you are a saint

Note to any person seeing this in the future:

This plugin only works on a Blender version of 2.6x (plugin was designed for 2.66 but 2.63 worked fine in my case), 2.7x and later just crashes instantly

I tested this even with moving, rotating and scaling the head bone with flexes really weirdly, and the plugin still transferred shapekeys perfectly.

[blaco]

Thats strange, it still works fine for me on 2.79, just tested it again

You can also apply your pose as a shape key, its a button on the armature modifier, then use the Blend from Shape function to blend the new shape into the Basis shape, it should apply the new vertice positions across every shape key without breaking anything

[ficool2]

Weird, whenever I try install it on 2.78 it just screams something about an invalid operation and closes

[RScott]

I just installed on 2.9 and activated..But where is the button? I haven't been able to find it...

[blaco]

Should be under the Misc tab on the left side toolbar in the 3d viewport

[RScott]

Thanks Found it...It had attached at the end of my PSK-PSA import tabs!
