--------- Hi guys! I'm new to the SDK and have a short question. Is it possible to access tangent and binormal vectors from a C++ or Py4D plugin?
I can check if the normal channel of an attached material is true or false and I can access vertices, normals, texture coordiantes and indexes of an polygon, but I didn't found a way to access tangent vectors.
I'm currently writing an specialized exporter plugin and it would be really nice to export tangent and binormal, or at least tangent vectors.
Does anyone know how to access them?
Thanks in advance, nkei666

Do you need them in a material? If so you can use VolumeData::GetDUDV(). In case a VolumData is not avaible you have to calculate them on your own.
cheers, Matthias

Thanks for the answer. I guess I need to compute them on my own.
