I’m trying to get an FBX file with tangent space information in it (Vertex tangents and bitangents). FBX is the format supported by the tool I’m using (Uno, a beta development tool). I’m not having any luck: my exported files lack any tangent information.
I’m new to modeling and blender. The FBX reference for blender says it exports tangents I assume I’m just doing something wrong. I’m looking to fulfill just a basic use-case now:
- Create a basic model (or rather, import one)
- Create the UV mapping (this I can do)
- ? generate tangent space ? (am I missing something here?)
- Export to FBX
- Import into target platform and apply texture
I’m not looking to create textures in blender now. I just want basic objects exported to which I can apply other textures. I have normal maps for these textures and the pipeline has tangent space calculations.
How do I get the tangent information in the exported FBX file?
