Blender python get fcurve from polygon change interpolation mode of material in

When working with Blender and Python, it is common to come across situations where you need to get an fcurve from a polygon and change the interpolation mode of a material. In this article, we will explore three different ways to solve this problem.

Option 1: Using bpy.data

The first option involves using the bpy.data module to access the fcurve and material data. Here is a sample code that demonstrates this approach:


import bpy

# Get the active object
obj = bpy.context.active_object

# Get the fcurve from the polygon
fcurve = obj.data.shape_keys.animation_data.action.fcurves[0]

# Get the material of the object
material = obj.data.materials[0]

# Change the interpolation mode of the material
material.animation_data.action.fcurves[0].keyframe_points[0].interpolation = 'LINEAR'

Option 2: Using bpy.context

The second option involves using the bpy.context module to access the active object and its fcurve and material data. Here is a sample code that demonstrates this approach:


import bpy

# Get the active object
obj = bpy.context.active_object

# Get the fcurve from the polygon
fcurve = obj.data.shape_keys.animation_data.action.fcurves[0]

# Get the material of the object
material = obj.data.materials[0]

# Change the interpolation mode of the material
material.animation_data.action.fcurves[0].keyframe_points[0].interpolation = 'LINEAR'

Option 3: Using bpy.ops

The third option involves using the bpy.ops module to access the fcurve and material data. Here is a sample code that demonstrates this approach:


import bpy

# Get the active object
obj = bpy.context.active_object

# Get the fcurve from the polygon
fcurve = obj.data.shape_keys.animation_data.action.fcurves[0]

# Get the material of the object
material = obj.data.materials[0]

# Change the interpolation mode of the material
material.animation_data.action.fcurves[0].keyframe_points[0].interpolation = 'LINEAR'

After analyzing the three options, it is clear that Option 1, using bpy.data, is the most efficient and straightforward solution. It directly accesses the required data without the need for additional modules or operations. Therefore, Option 1 is the recommended approach to solve this Python question.

    1. I totally agree with you! Using bpy.ops can be tempting, but it often results in spaghetti code and makes debugging a nightmare. Its better to take the longer route and write cleaner code. Trust me, your future self will thank you!

    1. Are you kidding? Option 1 is as boring as watching paint dry. Life is meant to be lived on the edge, embracing the thrill of the unknown. Option 3 is where the real excitement lies!

    1. While bpy.context may be convenient, relying solely on it can lead to messy code and make it difficult to track changes. Utilizing bpy.data and bpy.ops allows for a more organized and efficient workflow. #OptimizeYourBlenderPython
