Remove items from memory

Support Python Support

Hello!

How do you delete items from memory that were created via python and no longer needed?

Especially those two:

  • Bezier curves (bpy.data.curves)
  • Shape keys (bpy.data.shape_keys.values())

They stay even if the users have been deleted until I restart blender.

Cheers

Oh, just found this useful script:

import bpy

def cleanMemory( meshes = True, curves = True , materials = True ):

    n = 0

    if meshes:
        for datablock in bpy.data.meshes:
            if datablock.users==0:
                bpy.data.meshes.remove(datablock)
                n += 1

    if curves:
        for datablock in bpy.data.curves:
            if datablock.users==0:
                bpy.data.curves.remove(datablock)
                n += 1

    if materials:
        for datablock in bpy.data.materials:
            if datablock.users==0:
                bpy.data.materials.remove(datablock)
                n += 1

    print("cleanMemory removed %i data blocks" % (n))
    
    return(n)

cleanMemory()

Just don’t know how to implement shape keys right now…
