AttributeTypes
AttributeTypes()Enumeration of attribute types in Blender.
Each attribute type has a specific data type and dimensionality that corresponds to Blender’s internal CustomData types. The dtype values use explicit NumPy types (e.g., np.float32, np.uint8) that match Blender’s internal storage precision.
Notes
All float types use np.float32 (not Python’s float or np.float64) as this matches Blender’s internal 32-bit float storage. BYTE_COLOR uses np.uint8 (unsigned) as it corresponds to Blender’s MLoopCol struct which stores color components as unsigned char values (0-255 range).
