FBX will export only one blendshape

[lauris47]

Hey,

I have a character with different blend shape emotions, however only one and specific will export to fbx format.

Others will be visible in fbx, but changing number/slider won't affect skin at all. In Maya it works perfectly.

I tried:

Exporting only one blend shape (one of that did not work) - doesn't work.

Exporting all in different order, redoing blend shapes with history cleaned out. 

Reinstalling FBX.

Tried out on 2016 Maya version (I use student 2015)

Deleting History, non-deformer history. Exporting and importing skin maps.

Unlocking normals

Non of those worked.

Any ideas what is this?

That was a long tried and error run, but I managed to solve this.
The problem must have been with some sort of non removable history of a copy model of blend-shape.

So to not create all of my blend-shape models from scratch I did the following:

1. I deleted history of all models;
2. I created 20 copies of original model (because I will create more blend shapes in future and  I think 20 is a good amount, and I do not want to copy original model from the point where history is modified other blend shapes, skin etc... The reason I believe causes the issue, mentioned at the beginning);
3. Delete history again of all models;
4. Then I selected one of older blend-shapes and copied attributes (transfer attributes) to the new selected copy of original model (New blend shape copy) to copy vortex points;
   (Options in picture)
5. Then I deleted history of all of copy and original models again;
6. Finally I did "blend-shapes" from new copies;

All works inside fbx file and Unity game engine that I am exporting those to.
Hope this helps to someone else!

glad you got that sorted but it seems to be a different issue to my problem. Deleting history did not help.

I get this error when the blendshapes are present in the scene during export

//

The Morph Target object's controlling slider may not have been deleted.

The morph target object : / Blendshapes_Group / Abdomen_BLND / Abdomen_BLNDShape is not available in the scene.

Ignoring this target.

The morph target object : / Blendshapes_Group / Male_BLND / Male_BLNDShape is not available in the scene.

Ignoring this target.

The morph target object : / Blendshapes_Group / AbdomenFlat_BLND_GEO / AbdomenFlat_BLND_GEOShape is not available in the scene.

Ignoring this target.

//

So I delete the targets before export (the blendshapes still work in the scene) which removes the error but I still don't get any blendshapes in the resulting export.

Apparently much simpler solution is to just delete all blend shape models (by delete button, not some fancy way) just before exporting to FBX. Then when it is exported undo if you still need them.

Strange, exactly this works in my scene (Maya 2015 sp6)

How do you create your blend shapes ?
