Certainly! Exporting tangents in Blender 2.80 using Python can be useful for various tasks such as transferring animations or shading information between different software or pipelines. Here's a step-by-step tutorial with code examples to guide you through the process:
Before you start writing the Python script, make sure you have a Blender scene with a mesh object. This tutorial assumes you have some basic knowledge of Blender's interface and Python scripting.
Ensure that the Blender Python API (bpy) is available for scripting. Open the Blender Scripting workspace, create a new text file, and save it with a .py extension.
In Blender, tangents are part of the loops within a mesh. We'll iterate through the loops of each polygon to access and export tangent data.
This script retrieves the tangent information for each loop in the active mesh object and prints it. You can customize this part based on your export requirements.
Now, let's modify the script to export the tangent data to a file, for example, a CSV file.
Replace "/path/to/your/exported_tangents.csv" with the desired output file path. This script exports tangent data to a CSV file with columns for X, Y, and Z components.
Save the script and run it in Blender. Ensure you have the correct mesh object selected before running the script.
This tutorial provides a basic example of exporting tangents in Blender 2.80 using Python. Depending on your specific needs, you might need to adjust the script or explore additional Blender Python API functionalities.
