Project Description

godot-blender-exporter is developed intend to create a better workflow from Blender to Godot Engine. It is designed to support directly exporting mesh, armature and animation to godot scene, besides it is expected to have a support for exporting blender cycle materials to godot materials.

Completed work

• skeleton
  • commit:export armature node
  • commit:fix zero bone weight issue
  • commit:exclude control bone
  • commit:fix exclude control bone lost parent-child relation
• bone attachment
  • commit:support bone attachment
• shape key
  • commit:support shape key
  • commit:fix shape key incompatible with non-applying-modifier
• animation
  • commit:support transform animation
  • commit:support value animation of shapkey, light and camera
• constraint
  • commit:support automatically baking constraint to action
• material
  • PR: support cyle material
• document for godot-blender-exporter
  • commit: basic instruction for godot-blender-exporter
  • PR: add workflow instruction for exporting multiple actions

Prove of work (screen shots)

material

Known issues

1. shape key exports to a very excessive size output file issue#58
2. animation constrait not implement in the most efficient way issue#67

Future work

1. have support for new blender2.8 working in progress
2. Cycle Material exporting has no support for Generated Texture Coordinate and noise texture yet
3. Cycle Material exporting has a very poor result for glass bsdf shader
4. Cycle Material exporting has no support for custom node groups
5. Cycle Material exporting has no support for true displacement
6. The exported godot shader code has some redundant assignment code, need some optimization (maybe implement in godot side)
7. The Blender shader distribution forumula multiscattering GGX is not very well supported (maybe implement in godot side)
