Blender 2.83: Python API

Compatibility

  • Add-ons: in bl_info, wiki_url was renamed to doc_url. wiki_url is now deprecated. (a0ea0153c2)
  • Custom shaders need to be patched using the function blender_srgb_to_framebuffer_space. This ensure the output color is transformed to the correct color space. (21c658b718, T74139)

Example of a patched fragment shader:

out vec4 out_color;

void main() {
  vec4 srgb_color = vec4(0.5);
  out_color = blender_srgb_to_framebuffer_space(srgb_color);
}
  • Blender version numbers changed to standard MAJOR.MINOR.PATCH format. Most scripts will continue to work without changes.
    • bpy.app.version now returns (MAJOR, MINOR, PATCH). The PATCH version is 0 for the first stable release and increases for every bugfix release. Sub-version numbers or letters are no longer used.
    • bpy.app.version_string now includes Alpha or Beta for releases under development, for example 2.90 Alpha.
    • Add-ons compatible with Blender 2.83 should set "blender": (2, 83, 0) in bl_info, or lower if compatible with earlier versions.

New

  • Nodes: new bl_icon on custom nodes to display an icon in the node header. (120a38c120).
  • New foreach_set and foreach_get methods on array properties like image pixels. This is significantly more efficient than accessing individual elements. (9075ec8269)
