How to get the download size to 10mb for quest

[stickstick]

Hello, I'm stuck on 17.73 MB on an avatar. This is killing me mentally and physically.

Have you used Dark's optimizer? It merges materials, deletes unused blendshapes, edits the fx layer, etc into an optimized copy of your avi, while leaving the original untouched

ohhh!! i will try it thank you so much

[stickstick]

Hello! I'm sorry for the one-week delayed response.

To further optimize your model, you will need to use Blender in a destructive workflow.
This involves reducing the polycount, atlasing your textures, deleting or merging unnecessary bones, & removing unused blendshapes.
After these steps, you can use Unity plugins for more of a automated process, as these usually involve simple toggles.

In some cases, reducing texture resolution from 4K to 2K to 1K can significantly reduce file size.
I also manually adjust texture quality in Photoshop, lowering 8K JPEG quality from 100% to 87%, which greatly reduces file size. I then resize the textures back to 2K-4K in Unity of course.
I use several atlases for different texture types, such as one for normal paint textures & another for bump maps.

Scripts are another way to decrease file size.
If you know C#, optimize or delete unnecessary scripts.
For example, if a custom weapon has unused components, remove them to save space.

Also, consider using a different shader.
Poiyomi is very popular but often overcomplicated & bloated.
I recommend LilToon for most users as it's simple, & not as bloated.
However, for Quest, you might need to stick with the built-in Unity shader since that is the only shader that I know works.

If you're not interested in the learning process, & just want a Quest model, use the Unity plugins I mentioned.
Polytool can make a model Quest-compatible with a single click, although the result might not be visually perfect at times. Just make sure the polycount is reduced to 70K to avoid issues, & be mindful of any transparent materials on your avatar, such as blush.
Note 1: You can use [無料] Avatar Optimizer as an alternative to Polytool.
Note 2: Also, always use D4rkAvatarOptimizer before all your uploads.

I hope this helps!

Here's some paid Blender Plugin that many great Blender creators use:

• Quad Remesher. (Paid Blender plugin for reducing Polycount)
• SimpleBake. (Paid Blender plugin for Atlas textures)

Here's a Blender plugins I know most people use for their VRChat avatar:

• CATS. (Free Blender plugin, for like, everything, I swear.)

Here's a few Unity Plugins:

• PolyTool (Paid destructive plugin)
• D4rkAvatarOptimizer (Free Unity non-destructive plugin)
• [無料] Avatar Optimizer (Free Unity non-destructive plugin)

oh thank you for all the tips i will try this and update if it helps

You could also shrink the texture quality.
