YMAP vs MLO: choose the right starting point
They are not competing map formats. Understand the distinction before choosing a simple prop map or a structured interior.
CodeWalker, Blender and Sollumz: who does what?
Give each tool a clear job and stop asking the viewport to prove that the entire asset pipeline works.
Legacy and Enhanced: plan two build targets
Separate source from target-specific exports, follow current conversion guidance, and avoid claiming compatibility you have not tested.
Start with one object.
