Spell playback. A new Spells tab plays an RF force's cast, projectile and impact effects on the model, with looping.
Weapon effects. RF weapons, shields and held items show their particle effects, effect meshes and glow, with a +0 to +7 upgrade selector, and sit in the character's hand.
Armour effects. A dressed RF character shows the effects and glow of every armour piece and weapon it wears, with the same +0 to +7 selector in the Dress tab.
Monster effects. RF creatures draw the particle effects attached to their bodies, listed in the Scene tab with a toggle to hide them.
Shadows. Characters and creatures cast a soft shadow, with a Shadow toggle under View. Transparent screenshots never have one.
AI assistant control. Start gommoart.exe -mcp from an AI assistant and it can search and open models, dress them, play animations and spells, move the camera, take screenshots and captures, and export.
Town backdrops. On a game map the model stands in that map's town or start point, on open, level ground clear of water, walls and props.
Helmets and hair. Bellato and Cora keep their hair under a helmet and Accretia does not, matching the game. On RF Online 4.55 each helmet hides hair, face or both as the client does.
Orbit camera. The camera opens on the side of the model holding its weapon.
Hot reload on packed GTH clients. Reloading on a packed Gate to Heavens client is near instant, and files inside the client's packs take priority over loose copies.
Signed updates. Updates are signed, GoMMO Art refuses one that is not, and a downloaded update is only applied if it is newer than the running version.
