MLOs are interiors. They tend to be among the first serious categories of mod to mature after a Rockstar PC release. We work through why and what to expect.
Why MLOs come early
Less foundational toolwork than full exterior map modding. Demand-driven by RP servers - a community waiting in line. Authoring tools (3ds Max, Blender) already work for the format.
Once the archive editor and CodeWalker-equivalent exist, MLO authoring is the next thing the scene does.
Likely timeline
PC release + 3-6 months: small early MLOs. PC release + 6-12 months: more polished MLOs, marketplace begins. PC release + 12-24 months: NoPixel-tier MLO sets.
Speculative timeline. Specific dates depend on tool maturity and Rockstar's policy.
