I’m currently rebuilding core systems for an in-development MMORPG (Magickness™), focusing on long-term scalability rather than short-term implementations.

This phase has been centered around fixing and restructuring the character preview system — specifically how UI, meshes, and animation data interact inside Unreal Engine 5.4.


The Problem

The character preview system wasn’t behaving consistently:

  • Mesh alignment issues between MakeHuman base and Mixamo skeleton
  • Character preview rendering incorrectly in UI
  • Scale inconsistencies across imported assets
  • Animation mismatch due to skeleton differences

This created a chain reaction where UI preview, animation playback, and mesh proportions all conflicted.


What I’m Fixing

1. Mesh + Skeleton Alignment

Using a Mixamo-based skeleton with MakeHuman meshes required:

  • Rescaling mesh assets to match skeleton proportions
  • Verifying bone hierarchy compatibility
  • Ensuring consistent import settings across all assets

Small inconsistencies here break everything downstream.


2. Character Preview UI Issues

The preview system itself needed adjustment:

  • Camera positioning inside the UI
  • Mesh anchoring and offsets
  • Consistent scaling so characters render correctly across all customization states

This is one of those systems where visual bugs often come from underlying data inconsistencies.


3. Animation Pipeline Stability

Animations imported from Mixamo required cleanup:

  • Verifying retargeting settings
  • Adjusting animation playback within UE5
  • Ensuring animations match updated mesh proportions

This is especially important early — animation pipelines become painful to fix later if the foundation is wrong.


AI-Assisted Workflow

I’ve also been integrating AI (Claude) into the workflow — not as a game feature, but as a development tool:

  • Reviewing system logic
  • Identifying inconsistencies in setup
  • Accelerating iteration when debugging pipelines

Used correctly, it acts more like a second set of eyes than a replacement for engineering.


Why This Matters

This is part of a broader foundation phase.

Instead of building forward on unstable systems, I’m:

  • Fixing pipelines early
  • Standardizing asset behavior
  • Building systems that can scale as the project grows

It’s slower upfront, but prevents exponential problems later.


Project Context

Magickness™ is a discovery-driven MMORPG built around:

  • System-based progression (not predefined classes)
  • Player experimentation and mechanic combinations
  • Emergent gameplay systems

This stage is focused entirely on making sure those systems can actually support that vision.

If you’re working with UE5 + Mixamo + custom meshes, I’d be interested to hear how you’re handling pipeline consistency — especially around preview systems and scaling.
