Applying modifier on object with shape keys

[EmperorFaiz.wav]

Is there a way, plugin or whatever loophole for me to apply modifier (mirror, subdivision) on an object with shape keys?

I made a test with shape keys, added mirror, subd and array, no issues, they all work.

How? I always get the "modifier cannot be applied to a mesh with shape keys" whenever I do that.

If an object has shapekeys, it will not allow you to apply modifiers (which has always seemed dumb to me, especially for a mirror modifier) However that said, there once was a addon that would duplicate the object to match the shapekeys on both sides by breaking the moving mesh down into objects, then pin it back together and reapply the shapes. It was really clunky.

I had a base shape key and one other which was a cube with one vertex moved. Maybe more complex shape keys prevent modifiers?

Another way to do it would be to export the object as a FBX or a DMX, (which will apply modifiers as the model is built) then import the assembled FBX/DMX back into the scene. It will keep the shapekeys in the FBX, Make sure to apply ALL Transforms before doing this. so the object will retain its Location offset, rotation and scale from the origin point.

386 verts, blender lets me add any modifers...

I'm using v2.82.7, which version are you using?

v2.83.5. Also, did you ever try to press the "Apply" button an any of those modifiers? That's what I meant "applying modifier".

Huh, I'll give this a try

Ahh, I misread 'apply', no it doesn't allow.

Well bad news. The shape keys and vertex group are removed from the fbx model while using dmx export doesn't work because of weight limit despite I already set the weight limit to 3.

Snark-frugle-marj-fricker-ack! I was sure that FBX exported Shapekeys, but this has been a problem since before time with Blender. Sorry about that...

DMX, try setting the Weight Link Cull Threshold to about 0.26 and try your export again. It should go through.

Tried FBX, DAE, Alembic, DMX and SMD (with VTA) on a mirrored object with Shapekeys. The only ones that apply the modifiers and imported shapekeys correctly were DMX and SMD (when the VTA is imported on top of it.)
