I'm testing the PiStage1.2.0 version. I made a simple rigged file named “boy_setup”. This file is simply skinned with the default skeleton tool of Maya. When I previewed the “boy_setup” with Piview, I found that the geometry was hard edge display. Please see the following picture. I have found that as long as the model is rigged, hard edges will appear in Piview. I would like to ask, for rigged files, in order to display soft edges in Piview, what kind of setup work do I need to do ahead of time? Thank you very much.
This issue sometime appears because the vertex tangents are computed by default engine.
It could be solved by the following steps:
1. Check out your rigged asset "boy_setup" from content list of PiManager.
2. Open UE, then double click "boy_setup" to open skeletal mesh editor in UE4 content browser.
3. Set the item Import Normals and Tangents in comboBox of Normal Import Method in Import setting panel.
4. Click Reimport Mesh, then the mesh display should be updated as it in Maya.
5. Save it in skeletal mesh editor.
