Meccha Chameleon Controls and Keybinds

Knowing the Meccha Chameleon controls is the difference between a disguise that fools every seeker and a blob that gets spotted in five seconds. The painting system is the heart of the game (sometimes searched as "mecha chameleon" with a single c), so this page walks through the key binds that matter most, how to tune your camouflage, and why your input device choice really matters.

The two controls that matter most

The whole camouflage loop runs on two default keys:

• Paint mode — F. This opens paint mode, where you sample colors and apply them to your body.
• Sample / eyedropper — Spacebar. With paint mode open, aim at a surface and press Spacebar to pick up that exact color.

Everything else (movement, looking around, interacting) uses the standard first-person layout you would expect. But F and Spacebar are the two you will press constantly, so commit them to muscle memory first.

HSV sliders for tuning

Sampling a color gets you close, but lighting in the room rarely makes a single sample perfect. That is where the HSV sliders come in. After you sample, fine-tune Hue, Saturation and Value to nudge your color so it matches the surface under its actual lighting.

Just as important, set your material properties: metallic and roughness. A glossy body shining against a matte wall (or a matte body sitting on a shiny surface) is an instant giveaway, no matter how good the color match is. Dial these in so your blob's finish matches whatever you are hiding against.

The painting loop, control by control

Here is how the keybinds fit into a clean disguise:

1. Pick your spot and pose first. Crouch, lie flat, curl into a ball or press against a wall before you paint, because pose changes your silhouette, which is the first thing a seeker scans.
2. Open paint mode with F.
3. Sample with Spacebar — grab 3 to 4 colors: a base mid-tone, a shadow tone and a highlight.
4. Paint in layers — broad base tone first, then shadow and subtle texture, then a sparing highlight. A single flat color is the number one giveaway.
5. Tune with the HSV sliders and set metallic and roughness.
6. Pose check and freeze — confirm it reads from the angles a seeker approaches (no unpainted back), then hold completely still.

The full breakdown with examples lives in the paint guide, and the practical tips page has more on shape, shadow and angles.

Mouse and keyboard vs controller

A controller is supported and tagged on the Steam page, but for serious play, mouse and keyboard are strongly recommended. Painting freeform camouflage demands precise aiming when you sample a surface and careful, controlled strokes when you apply color. A mouse gives you that pixel-level accuracy; a thumbstick simply cannot match it for fine work.

If you only have a controller, you can absolutely still play and have fun, especially in casual lobbies. But if you want your disguises to hold up against sharp seekers, plug in a mouse. This is also part of why the Steam Deck experience, while Playable, is harder than a desktop setup: trackpad input makes the precision painting more fiddly.

Tips for new hiders

• Spot before paint — pick where you will hide, then sample that exact surface.
• Never one flat color — always layer base, shadow and highlight.
• Set pose first — silhouette is what seekers scan before color.
• Match material, not just color — tune metallic and roughness.
• Check from multiple angles — do not leave an unpainted back.
• Once frozen, stay completely still.

For where to put all this into practice, study the maps and pick a game mode that fits your group. Plan your disguise with the free camouflage palette matcher.
