+This patch:
+- Resolves #554 The default_cloud.png texture used for items without an inventory image such as butterfly is a blank white square.
+- Resolves #539 Butterflies (each of the 4 butterfly textures) from codermobs has a false edge (cut curve) due to scaling.
+
+The model must be exported as follows to avoid bone orientation glitches:
+- Download and extract the special version of B3DExport from: https://github.com/minetest/B3DExport
+- Blender 2.8, Preferences, Add-ons:
+  - In the search box type B3D, expand any that appear, then click Remove.
+  - Install, choose the extracted py file.
+  - In the search box type B3D and enable the special version.
 
 To apply, set BUCKET_GAME then:
 cd EnlivenMinetest && git pull && rsync -rtv Bucket_Game-branches/butterfly_rearrange_patch-vs-220422-002/ $BUCKET_GAME
+rm $BUCKET_GAME/mods/codermobs/codermobs/projects/unused/butterfly_poikilos-blender3.0-nonworking.blend

+mv -v $BUCKET_GAME/mods/codermobs/codermobs/models/codermobs_butterfly.x $BUCKET_GAME/mods/codermobs/codermobs/projects/unused/
 
+Then exclude the projects folder from distribution to save space.
