Technical Feedback: Broken Modding Pipeline & Destructive Culling Standards

System Specs for Context:

CPU: Ryzen 7 5800X3D

GPU: AMD Radeon RX 9700 XT OC

OS: Nobara Linux (KDE Plasma)

Current Version: v0.8.0 (UE 5.6)

The Issue:
I am writing to address a significant regression in the quality of the current modding ecosystem. While inZOI was marketed as a next-gen, modular simulation game, the current community standard for “optimization” is destructive and technically redundant for high-end users.

  1. Destructive Mesh Culling vs. Transparency Masks
    99% of modded clothing currently on CurseForge utilizes “destructive culling.” Instead of utilizing UE5’s capacity for Transparency Masks or Material Overrides, modders are deleting the underlying body mesh geometry entirely to avoid clipping.

    The Problem: This creates “hollow” characters. If a user attempts to layer items (e.g., placing modded or even vanilla underwear beneath a dress), the geometry is simply gone.

    Hardware Waste: On a high-end system (RX 9700 XT), there is zero performance benefit to deleting these few thousand polygons. We have the overhead to render layers. Forcing a “low-end” mobile optimization standard on the entire player base kills the immersion of a next-gen sim.

  2. Incorrect JSON Slotting & Data Architecture
    Many modders are incorrectly slotting “Inner” garments (Underwear/Lingerie) into the GarmentBottom or FullBody slots.

    Result: This triggers the engine’s default culling for those slots, effectively “blocking” the InnerUnderId and InnerTopId layers. This is a fundamental misunderstanding of the inZOI layering system that leads to unnecessary mod conflicts.

  3. The CurseForge Feedback Vacuum
    The in-game CurseForge integration is currently “read-only.” There is no way to provide feedback to modders regarding these technical failures (hollow meshes, mis-slotted items) without leaving the game and navigating a clunky web interface. This has created a vacuum where modders assume “high download counts” equal “high quality,” despite their assets being technically broken for layering.

Requested Solution/Toggle:

Official Toggle: Please provide a "Force Render All Layers" or "Disable Default Underwear" toggle in the graphics settings.

ModKit Standards: Update the official ModKit documentation to discourage destructive mesh deletion in favor of vertex-paint masking.

We finally have a “Sims-killer” running on a world-class engine. Let’s not let it be dragged down by 2014-era modding shortcuts.
