Hi! I have a question regarding how to use <morph> properly. Collada docs says that only input sources in <vertices> are morphed, but every single exporter I have tried so far only exports POSITIONS inside that tag.
This is not very nice, because in almost all cases, normals (and potentially binormals/tangents) need to be morphed too. I want to implement being able to morph more fields, but it’s not clear at all how this would work in an actual DAE file.
If VERTEX is mapped to POSITIONS , how would I know how anything else is mapped to the <vertices> tag? I can’t find much info about this (examples) and the specification isn’t clear.
