    This was a very helpful video, thank you so much for taking the time to walk us through each step :D
    P.S. For anyone having issues with atlasing materials, make sure to complete these steps before you begin the atlasing step:
    ( File > External Data > Unpack All into Files > Use files in current directory )
    Now atlasing the materials shouldn't break your model anymore XD
    Also, if your textures aren't embedded in the fbx. model file when you export it to unity, import the atlas png. file into your materials folder. Then click on the texture file, and in the side menu, drag your atlas png. file into the *Albedo selection box, and it should update your model with your textures. You may have to do this for each texture file that your model has

    I ran into some issues with the CATS "Fix Model" feature. In case anyone else has these problems, here's my solutions.
    First, "Fix Model at the beginning of the video deleted my shoes. I fixed this by deleting the hidden body meshes (including the feet) and just doing "Fix Model" later on. Second, "Fix Model" deleted my irises. To fix this, I had to uncheck "Combine same Materials". You combine materials again at the end anyway so it was not a big problem. Other than that, everything worked great!
    Thanks for the helpful tutorial.

    Thanks, this helped me a lot!
    I'd like to note that I also had issues when merging to Atlas. But Found on Reddit a comment saying to go to Files -> External Data - > Unpack All into Files -> then whatever was the first option on the pop up. This allowed me to merge materials however I wanted but also made my model's colours off in Blender. HOWEVER I was easily able to get the colours back once I imported the model into Unity through shaders.

    ATLAS ISSUE FIX: There's a materials tab in optimization settings in the current version of VRoid Studio. Click the dropdown to change it from "Default" to "2" Materials. VRoid Studio will automatically do what CATS Atlas tool does. However with this fix, you will need to do most of your model editing in VRoid Studio (which, like Fazzie says is actually easier, use "E" to select the eraser tool). But you will perfectly get one material for your body and one for your face using this method!

      I'm no Picasso of 3d but you might want to consider using something called a toon shader in order to convey that outline (Toon shading will let you do cel shading and outlines, or just one or the other). I reccomend MrTriPie's toon shader tutorial to learn the very basics of how to do that shader.

    Could you just import the FBX file into unity and then use it as a traditional model for like a game instead of VR chat? jw. all the previous steps seem like a good way to cut down on poly and make it midpoly which is much better for performance.

    • @fazziesan5931

      You can combine all your clothes textures into 1 material, all your face parts textures (eyes, eyebrows, tongue, teeth etc) into 1 material, your skin textures into 1 material, and your hair textures into 1 material. So in total, 4 materials. Still more than 1 materials, but a lot less than 20++ materials

    • @fazziesan5931
      @fazziesan5931  3 роки тому

      Hi! Thank you for your kind comment, and I'm glad you found this helpful ^^ As for your question, did you combine all your textures into one material atlas? That can cause for it to look like that when imported into Unity. Also the type of shader that you use on the material atlas will change how the material look on the inside. The inside of my skirt is black when I use the VRM/Mtoon shader with cutout rendering type, and transparent when I use the VRChat/Mobile/MatCap Lit shader.
      Maybe if you want the inside of your skirt and sleeves to not be transparent, don't combine them into the material atlas - leave them as separate materials on its own. I haven't tried out this solution myself, but I suggest that you try it out in your case ^^ Do let me know if it fixes your problem!

    • @OLBarbok
      @OLBarbok 3 роки тому +1

      Some shaders have a "cull" option that disables either front or out, look for it in your shader or use poiyomi where it is under "Rendering options" if you want the inside and outside to show you have to turn cull off.

      I did leave the dress separate, but it still didn't work.. After a loooong while of experimenting, I actually fixed it by taking a duplicate of the dress separate and "flip" it, then put it back in my models materials, and "join" it with the original dress. This made the top of the dress show on the inside as well. Maybe not the best way, the "cull" option sounds much easier though, wish I knew that before hahaha, will definitely try that next time!

AND MAKE A GOD DANG VIDEO ON HOW TO OPTIMIZE A VROID MODEL IN BLENDER FOR VRCHAT THAT ISN'T OUTDATED! !
    Honestly, I can't find a single recent video tutorial that is up to date on this subject & all the videos now have TONNNNNNNNNNNS of issues. Particularly with this whole bullsh** Cats Plugin that doesn't work for sh**. There is always some error, or visual issue with the fix model button, & believe me, i've installed like 20 diff versions of both blender & the cats plugin, & even material combiner & the vrm add-ons, & some non-sense always happens. Line errors, avatar turns white or clothes disappearing after hitting that "Fix Model" button. That "Fix Model" button has given me PTSD. That Cats plugin is some Todd Howard sh**. "It Just Works"..... MY A********! !
    ...Or at the very least. Say FAK the Cats plugin, & do a tutorial on how to optimize a vroid model in Blender for VRChat MANUALLY without the dang add-On/Plug-In. PLEEEEEASE! ! Be the ONE faking person that hops on this sh**. I mean, there is a faking Creator Companion now. None of these tutorials even mention that. U don't even NEED Avatars or Worlds SDK anymore OR the VRM add-on. It comes with the dang Creator Companion app now lol... Someone has got to do something about this outdated BS bra. Real sh**.
    Pardon my language, but i'm pissed off at how ridiculously hard it is to send a custom VROID Model to VRChat. Wayyyyyyyy too many steps, & many of those steps have aged cracks in them. You follow a tutorial & you fall through the damn woodwork. I've been doing this for about 2 weeks now & I still have yet to succeed.

      I have this exact issue and I'm using the same version of blender as in the video, was there a solution to this? Edit; nevermind, I watched How to Import Vroid Studio 3D Avatars into Blender 3.4 and basically just using newer versions of everything, there were no issues. - blender 2.9 and newest version of addons
