@KoikatsuBlendlet3 years ago If you're using V4.2.0 or higher the KK plugin will try to separate the Bonelyfans and Shadowcast automatically when you click the "3 separate body" button, so you might be able to skip to ... 8

@Kikuflare3 years ago I discovered a way to fix the shapekeys that affect accessories/hair without going through the trouble of re-exporting model again in Koikatsu.
Through some testing, I found that after separating the clothes and hair as described at and onwards in this video, the shapekeys will also become separate. This means you can just click the Clothes or Hair group, go into the shapekeys list and delete all the shapekeys (highlight the shapekey and click the minus icon on the right) for these two groups and it will preserve the shapekeys in the Body group. ... 3

@YEDPG2 years ago Thanks for making this tutorial. I ran into a snag though. When trying to clean armature, I get key error "bpy_collection[key]: key "Armature" not found. All previous steps worked with no issues. Anyone know how to fix this? ...

@galbatorixiv3 years ago I'm having an issue where it wont import the textures it just puts me in the folder the textures are in. I tried selecting all the texture to import but just gives me a python error saying location unknown.
@

@kylekrafter89323 years ago Hey! Thanks so much for putting this together. When I run step 3, the cf_m_hitomi iris parts go into the clothes instead of the body, and that's been giving me a lot of trouble down the line since there's no option for eye position and the like... Wondering if you know what could cause that, as I've already tried re-exporting. Thanks again! ...
@

@cifer33273 years ago When I import the textures, it somehow messes with the form of the hair and makes it impossible to apply shaders correctly... Why could this be happening?

@Daemon8fx3 years ago Great Tutorial! I had an issue where the face was transparent, some issue with alpha apparently after i imported the textures, stil trying to fix that particular issue but the rest has been working nicely. 1

@Okralk3 years ago I've been following your tutorial step by step (it's rather good by the way!) and I have encountered a Blender issue where I could not import the textures (7 on KK Panel).

@Aelethil3 years ago So upon separating the hair It proceeded to double the mesh and cause a weird static/ screen door effect on me. I am going to attempt to leave them combined with the clothes as it only happens upon separation. Was wondering if there was a knwon fix for this lest I pivot to my old method for this specific step. ...

@nikolipwn3 years ago Seems that the shape keys are screwing up for me. Whenever I import the textures the mouth opens a noticeable amount rather than staying closed. I've tested it on multiple characters and can't seem to find what's causing this problem. ... 1

@ymah21253 years ago I'm stuck 1 minute into this part where I am supposed to select the bonelyfans and standard material, I cannot see them in the list in my Material Properties tab. Could I have missed something or exported something wrong? Maybe I forgot to import something? I'm going really slow, but I'll start from part 1 again just in case. ...
@

@lizzyamaranth41413 years ago Hiya again! I'm having an issue that some of the textures for my character are loading on the wrong clothing. From what I see it seems anything I separated off into groups got their textures alright, but the big bunch of textures in the "clothing" collection seemed to get jumbled up. (Occurs after using the 7th "Import Textures" step). ...
@

@rarecreature48623 years ago I do not know why, but first time I've tried I got to part 7 of the tutorial (the color shading) however I've done some mistakes on the model and thought I'd start from scratch. Now for some reason I'm getting the same error about: "Teeth_i_small_cl" not found. The only change to the model I've done was remove 3 accessories that were attached to the neck for some reason. ... 1
@

@KDenero3 years ago hello, i'm having an issue in the step 7, when I import the textures, my girl looks a messed up (the black and yellow are there, but her face looks horrible, her eyes are not visible and her torso is gone, clothes are okay but her skin is the issue) I also run into two different errors, one of them saying template body outline not found and the other is genMat.material.node_tree.nodes['KKShader'].node_tree.nodes['GeneralOut'].inputs['Alpha'].links[0] index out of range.
What do you think it could be the issue? I've tried running the latest Blender version and the one you used in this video (2.91.2), I tried two different versions of your KK Shader Pack (latest being 4.1.2 and then the one you use in this video), my HF Patch version is 3.8, and my grey mesh exporter is 1.0.2.
I sent this comment before but I think it was deleted for containing links, would it be possible to get a different way to contact you and provide images of my issues? Like a discord account or anything, I've been trying different things for hours but I don't know what to do anymore. ...
@

@BlitzProGaming13 years ago Is Bonelyfans necessary? Idk why, I've followed the instructions to a tee, but my model doesn't have it. Also whenever I separate the body, the shadowcast clips through portions of the model. any help would be cool

@akronhym15863 years ago Hi
i am kind of stuck in the "Import textures" step, when i hit the button everything goes fine until the following error shows up:

@

@ct30003 years ago I get an error when I click import textures, so for some reason my model didn't export textures into separate folder it threw them into the models which was fine for the tutorial so far. Once I hit import textures pointing to that folder though it errored that it wasn't the Textures folder. I tried renaming it "Textures" but then I get an even more scary error... ...
@

@ShinichiMechazawa3 years ago I kept crashing on step 6 using KK Shader Pack 4.3.1. I went out on a limb and tried skipping to step 7, which brought up an error message but didn't crash, at least. Step 6 worked after that, so I reran step 7, causing the model to render in black and yellow, like in the vid. I guess everything's working now? Here hoping I can follow along from here without a hitch.
Regardless, thanks for the tutorial! ... 2

@electr0monkey3 years ago Hi, I see here that you help the community in comments section, so I have one problem too.
When I try to import material templates I get this error message:
"", line 80, in execute body.material_slots['Template General'].material = tongueTemplate
KeyError: 'bpy_prop_collection[key]: key "Template General" not found'".
I also get similar error in Import Textures step: "", line 101, in execute newNode = hairMat.material.node_tree.nodes['HairTextures'].node_tree.copy()
KeyError: 'bpy_prop_collection[key]: key "HairTextures" not found'
Any idea how to fix it and go beyond that points? Thanks for the awesome tutorial and being so helpful! ...

@ivanshiny_3 years ago Hey, quick question, idk if you can help
I do everything that's in the videos, but when I go to import the textures to the model, the eyes appear completely black, even after moving to the shaders, and importing textures from there doesn't works.
Do you know what may be causing this? ...

@AnimeGirl65613 years ago Whenever I try to fix shapekeys Blender always crashes. I'm using the latest version of Blender and the latest KK plugin V4.2.2 3
3 years ago I got this error message, did I do something wrong? Or what's the problem?
Or can it have something to do with the fact that I renamed the textures accordingly before I loaded them into Blender?

@

@elsantko3 years ago Edit and resolution: I did not get the Gentex error when I redid this part of the tutorial and separated less objects.
If there's anybody in this comment section, I've run into an error when attempting to import textures that I didn't get before but I'm unsure what's different this time.
Python: Traceback (most recent call last):
File "C:\Users\USER\AppData\Roaming\Blender Foundation\Blender\2.91\scripts\addons\KK-Blender-Plugin\", line 126, in execute
newNode = genMat.material.node_tree.nodes['Gentex'].node_tree.copy()
KeyError: 'bpy_prop_collection[key]: key "Gentex" not found'
location: <unknown location>:-1
I can't seem to figure out how to fix this, I've tried the good ol' restart and changing the version of the KK Pack, could this be the script failing to find mask/maintex files for accessories on my character that do not have any?
Edit: the accessories without texture masks do disappear entirely with the Gentex error, I think my interpretation of what's happening in the script is sort of correct? Can someone clarify?
Plus I get all clothes textures a void black half the time but that hopefully gets fixed along with this, could the void be caused by the Bone/Shadow collection?
Edit: the clothes turning void black is fixed by entirely disabling the Bonelyfans/Shadowcast collection, the Gentex error is still a mystery. Is it safe to continue with the error?
I'm using Blender 2.91.2, KK Blender Pack 4.0.6, CATS 0.18.0. Thank you... ...
@

@MarvayVT3 years ago For others: When importing a male character, the body goes on the clothes layer. You need to separate that from the clothes too and then merge it by selecting the separated layer and "Body" and pressing ctrl + J

@Sahfiel133 years ago I want to cry. I want to cry so bad, I tried another tutorial way back and this tutorial was going so well. I thought things would be different this time and stuff would work. Then this stupid error thing pops up when I try to import textures. Everything seems fine until this point. I ~~think~~ it might be that the file browser when I try to select the folder doesn't seem to select the folder like how it does for you. Like, I click the folder and it goes inside instead of selecting it and when I click it seems to wanna run based on whats at the bottom of the screen. It might be selecting the folder correctly but it displays differently than when you selected the folder. This is the error.
