KKBP 7.2.1

See the readme for installation and usage instructions

Changes for V7.2.1

• Fixed crashes when creating a material atlas!
  • This feature will now use atlas generation scripts borrowed from the material-combiner-addon
  • You will have to install pillow by clicking on the button in the KKBP panel (this uses pip, so it requires an internet connection)
• More headmods will now import thanks to @VickyFrenzy!
  • The plugin expected all body materials to be present, but some headmods either remove or rename these materials, causing errors. Now it will skip some materials if they don't exist, allowing the headmod to at least import so you can fix it manually
• Chinese translation fixes and updates by @AnalogKnight!
• Backported the plugin to work in Blender 3.6
  • Only the import features work, so no exporting from 3.6
• Added a button to revert all of your finalized materials back to the -ORG / "heavyweight" version of the material
• Foot IKs will finally work on taller characters
• The "prep for target application" button will now allow you to simplify the KK and PMX armatures
• Add back linux / mac support (again)

KKBP 7.1.0

See the readme for installation and usage instructions

Changes for V7.1.0

• Blender 4.2 LTS support!
  • Please note you need the new version of mmd_tools
• Koikatsu Sunshine exporter bugfix by @Guerra24!
  • This fixes colors not showing up on KKS exports that had their material set to "Koikano"
• Replaced Generated Face Normal smoothing with a new geometry nodes setup from @MoriMorinya! (original node group by aVersionOfReality)
• Added a button to import a single ripped animation from the game onto your model!
  • This feature requires Rokoko studio live plugin to be installed
  • This supports Mixamo animations too thanks to @hsxfunc
• Import KeyError fixes by @justturniphead!
• Chinese translation updates by @AnalogKnight!
• Normal maps are now loaded into the optimized material thanks to @FrankV724!
• The KKBP plugin can now generate a material atlas by itself!
  • The plugin also automatically generates a copy of your model that uses the atlas
  • This feature does not have a pixel limit, so if the atlas is too large, you can split up your objects and re-generate it
• Streamlined the KKBP main panel!
  • There's now only one button for importing, one for optimizing materials and one for exporting
  • If a button in the panel cannot be used, it will now be grayed out. Some features (like the animation import feature) require you to use the Rigify armature, and other features (like the prep button) require you to use the KKBP armature
• The plugin will now attempt to give you progress information during very long sequences, like when finalizing materials or bone simplification
• Generating dark colors and textures can now be skipped to slightly speed up import times
• Blue pixels on textures should now be fixed
  • This appeared to be an issue on certain blender versions. The textures are now generated by a python script, so this issue should not happen again.
• Updated the colors in the KK Shader to look good in the default "Blender dark" theme
• Updated the plugin to be a Blender 4.2 extension (it is no longer a legacy addon)
• Renamed the folders inside of the exporter zip to be clearer
• Added decompiled source code for the KKBP_Exporter.dll to the exporter zip (thanks to @Guerra24)
• Moved wiki and usage instructions to a github pages site: https://flailingfog.github.io

Click to show the V6.1.1 changelog

• Rigify armature updates by an anonymous contributor! (Changelog copy-pasted below)
  • 'Rigified' the new rigged tongue;
  • Moved the eyes and rigged tongue bones to their own layers to reduce clutter in the face layers;
  • Fixed the skirt bones alignment when converted, and also added the sixth bone (cf_j_sk_##_05) to the chains, just in case;
  • Characters without skirt bones are now supported;
  • Connected hair/accessory bones in the same way the CATS plugin does, and changed their widgets from 'circle' to 'limb' type, so the connections with their MCH parents are more apparent;
  • Enabled a small new Rigify adjustment to the toe bones for Blender 3.2+ (this one: https://www.youtube.com/watch?v=H80AjLWgECY );
  • Enabled a small new Rigify feature to the limb bones for Blender 3.3+, which allows you to scale the arms and legs uniformly by scaling the gear control bone at their base;
  • Now the script that is run after the Rigify conversion automatically changes parents and armature modifier targets to the generated rig for all mesh objects in the scene that are related to its metarig; it does it without relying on object names so it should be safe even with multiple characters in the same scene (it detects its metarig from a common bone with a random alphanumeric string in its name). In other words, there's no more need to parent objects with empty groups.
• Multiple bugfixes by @MediaMoots!
  • See #266, #257, #281
• Basic Cycles shader support!
  • This will make the KKBP materials work in Cycles
• Basic Lightning Boy Shader support!

  • If Blender crashes during the baking process, the baking process will now resume where it left off instead of trying to bake everything again
• Added addon preferences
  • These won't reset when blender is closed

Changes for V6.0.0

Huge feature and usability updates by @MediaMoots!

• The KKBP exporter now works in Koikatsu Sunshine!
• The KKBP Blender plugin now works in Blender 3.1+!
• All outfits are now exported!
  • These are automatically exported from Koikatsu
  • These are available as hidden objects after the model is imported into Blender. They are parented to the armature
  • If you don't want to use these, you can shorten your import time by deleting the "Outfit ##" folder from the export folder
• Alternate clothing states (shift / hang state) can now be exported!
  • Export these by checking the "Export Variations" box in Koikatsu
  • These are available as hidden objects after the model is imported into Blender. They are parented to the outfit object
• Hitboxes can now be exported!
  • Export these by checking the "Export Hit Meshes" box in Koikatsu
  • These are placed in their own collection when the model is imported into Blender
• The tears object is now exported and available as new shapekeys on the body object!
  • These are parented to the body
  • The tears material also has settings to allow minor color edits
• The eye gag object for heart eyes, firey eyes, etc is now exported and available as new shapekeys on the body object!
  • These are parented to the body
  • The shapekeys will automatically hide the eyes and eyeline materials when active
  • The swirly eye rotation speed, heart eye pulse speed and cry/fire eye animation speed can be changed in the Eye Gag materials
• The animated tongue is now exported!
  • This is parented to the body object and hidden by default
  • The rigged tongue doesn't use shapekeys like the rest of the face does
• Shapekeys are more accurate than before!
• The heart and sparkle Eye overlays are now exported
• Eyewhite shapekeys are fixed on the exporter-side now!
  • This means Blender is less likely to crash when importing the model
• Small fangs are now exported!
• Accessories are now automatically linked to the correct limb bone!
• Eye and overlay textures are now scaled automatically!
• Hair shine, eyeshadow, nipple and underhair UVmaps are now exported!
  • Thanks to that, these items no longer need to be set and scaled manually for each character
• Converted Normal Maps for use in Unreal and Unity are now exported
• Separated objects can now be exported with the "Export separated meshes" button
• A lot of character info is now exported
  • Check the .json files in the export folder for info on materials, accessories, objects, renderers and bones
• Exported character heights are 4% more accurate
• Texture suffixes are shortened
  • Image names over 64 characters long would cause blender to cufoff the filename, so this means long texture names are less likely to cause issues during import
• The Koikatsu / BepInEx console will now be print out each mesh being exported. If the exporter is not working for a specific character, accessory or clothing item, you can use this to track down what is causing the exporter to fail.
  • These messages are prefixed with [Info : Console]

Rigify armature updates by an anonymous contributor!

• Better Penetration bones will now be placed in the "Torso (Tweak)" layer when converting to the Rigify armature
  • You need to use the Better Penetration armature type in Koikatsu for these bones to appear

Unity normal blending and mirrored blush scaling by @poisenbery!

• Unity normal blending is an alternative normal map detail blending method that can be accessed in the "Raw shading" group
• Mirrored blush scaling is an easier way to scale the blush and eyeshadow if the texture is symmetrical. This can be accessed in the "Blush positioning" group on the Face material

Better face normals using shader nodes!

• The face now uses a bastardized version of the Generated Face Normals setup described in this post by aVersionOfReality
• This setup is disabled by default for performance reasons. Enable it by going to the face material > swap the "Raw Shading" node group to "Raw Shading (face)"
• This setup only works in Blender
• The GFN Empty position and scale can be edited by unhiding it. It's parented to the armature
• The GFN options can be edited in the node group called "Generated Face Normals" inside of the the "Raw shading (face)" group

Plus some misc changes to the Blender plugin:

• Added a one-click option for importing models!
  • Hair is now separated from the model automatically, so the entire import process has been reduced to a single button
  • The behaviour from V5.0 (where you can separate objects as you please) can still be accessed by changing the "Don't pause to categorize" option on the upper right to "Pause to categorize", then pressing the "Finish categorization" button when you're done.
• The main plugin UI can now be fully translated!
  • Current languages: English, Japanese (日本語)
• Material baking is now done through the use of Geometry Nodes!
  • This works with multiple UV maps, so you no longer need to create a new mesh for hair highlights or anything that uses a separate uv map
  • You can also speed up the baking process by skipping the dark and normal bakes if you don't want them
• Exporting can now be done without installing the CATS addon
  • Material Combiner is still required if you want a material atlas
• Added a simplification choices menu to the export prep button
• Removed the vanilla armature type toggle in favor of a menu
  • There's four options to choose from. Check the tooltip for a brief description of each option
  • The ability to switch between armature types after import was removed
• Shapekeys on clothes and hair objects are now deleted
  • Shapekeys only affect the face, so these weren't needed anyway
• The Eye, Eyebrow, Eyewhite, Eyeline and Nose materials are now marked as freestyle faces by default (for freestyle exclusion)
• Lipstick and Flush textures are now loaded into the face material
• Added a safe for work mode toggle that probably works
• The permalight/permadark texture has been merged into one file
• Python errors are now copied to the KK Log in the Scripting tab on the top
• The import directory string listed in the KK Log is now censored if it detects your Windows username
