Light an MMD scene with Ray-MMD

Start from a working scene and add light and materials in stages while keeping a way back.

PRACTICE OUTCOME

Two comparable before-and-after stills and a saved Ray-MMD scene.

STEP BY STEP

01

Make a no-effect reference

Open the scene copy, keep a fixed camera and render a starting still. Note areas already too bright or dark.

Check: You have a baseline image to compare.
02

Load the basic system

Following the project wiki, add ray.x, the controller and an appropriate skybox. Save another copy before assigning materials.

Check: The scene reopens without errors and the controller is present.
03

Assign materials and ambience

Apply main.fx where appropriate according to the official guide. Add ambient light before increasing exposure; do not fix a black scene by stacking effects blindly.

Check: The character separates from the background without major blown-out areas.
04

Compare and troubleshoot

Render the same camera, compare with the baseline and disable one effect at a time if something fails. Keep a list of files and settings used.

Check: You can reproduce the result and return to the no-effect version.

IF SOMETHING FAILS

Quick checks

  • If the scene is black, check MME, main.fx assignment and ambient light before adding more effects.
  • If performance drops, simplify the scene and test a still.
  • If a model looks wrong, inspect its materials rather than assuming every PMX uses the same setup.
