Blender 2.60 Python Updates


Various callbacks, to replace scriptlinks as existed in 2.4x. Example on how to use:

def stats_call(context):
    print("Thanks for calling!")
bpy.ops.render.render(animation=False, write_still=True)

Currently available callbacks:

  • frame_change_pre, frame_change_post
  • render_pre, render_post
  • render_stats
  • load_pre, load_post
  • save_pre, save_post

GLSL Shader Export

New gpu module with export_shader(scene, material) function to export GLSL shader. This returns the GLSL shader that blender generates to produce the visual effect of material in scene for the purpose of reusing the shader in an external engine. This function is meant to be used in a material exporter so that the GLSL shader can be exported entirely. The return value is a dictionary containing the shader source code and all associated data. (TODO documentation link goes here)


  • Modified behavior of Vector() * Matrix() multiplication, this is now implemented as (row * vector) multiplication - r39445, r40360
