"Texture has zero width or height" when importing fbx file.

Hello there @ArcaneGel2!

The "zero width or height” is usually tied to a corrupt FBX, or missing content inside, like an assigned texture. There are also calls to missing smoothing groups, and payload. Let’s test some methods for resolution in Blender:

  1. Check the Shading tab, ensure that an image file is tiend to the Image Texture node, and check for any empty or broken nodes

  2. Make sure any texture under use is saved somewhere in your machine (Image > Save As)

  3. When exporting again, enable “Apply modifiers”, enable “Smoothing”, and set it to either “Face” or “Normals”

  4. Also, check “Export Normals”, “Export Tangents”, and use FBX 2014 format
