Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Maya to UE4 FBX export blendshape issues

I'm having an issue with exporting an animation that uses corrective blend-shapes driven by the joints. The blend-shapes do export because I can see the sliders change with the animation in UE4, but it looks like the shape isn't deforming as it should in contrast to how it looks in Maya. I have all the proper check boxes checked, I even tried baking the animation/simulation, using older/newer versions of the FBX plugin but nothing works.

I'm at my wits end, hoping somebody here may be able to solve my problem.
I don't know if it matters but the character is rigged using the ART tool.

I did a simple test with a skinned cylinder with 1 blendshape and Maya's FBX just refuses to bake the blendshape. All proper checkboxes are activated and I went through all versions of FBX....still nothing, I even baked the simulation/animation.

The solution was so simple I lost my mind.......Classic Linear skinning.....that's it............I had Dual Quaternion activated.........2 weeks.......gone...no google search made any mention of this when it came to exporting with FBX.

I am doing a most basic blend shape animation: One sphere + blend shapes = A squashed version of the sphere. But no luck... UE4 do not recognizes it. This blend shaping has nothing to do with linear skinning or Dual Quaternion (And I do not know whatever these are) Could you please explain your pipeline for someone who has no brain at the moment.
