Rough ↔ Gloss

Roughness and gloss describe the same thing from opposite ends. Roughness 0 is a mirror, gloss 0 is completely matte. Unreal and glTF say roughness, Unity says smoothness, older pipelines say glossiness.

Moving an asset between them means inverting the map. If a material looks like polished plastic when it should be raw concrete, or everything went matte after an engine switch, this is usually why.

Is smoothness the same as glossiness?

For this purpose yes. Both are just 1 minus roughness.

Does it need a gamma step?

No, and adding one would be a bug. Roughness is a plain value, so this is a straight inversion of the numbers.

All tools

Edge Padding: Bleed UV island colors outward into empty space so textures stop showing dark seams at lower mip levels. Runs in your browser.

ORM Packer: Combine ambient occlusion, roughness and metallic maps into a single packed RGBA texture, with control over which map goes in which channel.

Tiling Checker: Preview a texture tiled 3x3 with the seams highlighted, plus a half-offset view, so visible edges and obvious repetition show up before the asset ships.

Material Preview: Preview albedo, normal and ORM maps together on a lit sphere or cube, without exporting into Unreal or Unity to check how a material looks.

Height to Normal: Convert a height, bump or displacement map into a tangent space normal map, with adjustable strength and a choice of DirectX or OpenGL output.

Combine Normals: Layer a detail normal map over a base one and keep the detail from both, instead of averaging them into something flatter than either.

Normal Strength: Scale how much a normal map bends the light, without rebaking it. Keeps the map valid instead of breaking it the way a contrast slider would.

Levels: Set the black point, white point, midtones and inversion of a roughness, AO, height or mask texture, with a live preview.

Flip Green: Invert the green channel of a normal map to switch it between DirectX and OpenGL, which fixes normals that light inside out.

Renormalize: Restore a normal map after resizing, blurring or compression has weakened it, without changing which way any of it points.

Material from Photo: Generate albedo, height, normal, roughness and AO maps from a single photo, as a starting point you then tune.

Seamless Maker: Turn a photo or texture into one that repeats cleanly, by shifting it by half and blending the mismatched edges away.

AO & Curvature: Get ambient occlusion, curvature and cavity maps out of a normal map, with no high-poly mesh and no baker, for edge wear and dirt masks.

Channel Split: Split a packed ORM, RMA or mask texture back into one grayscale map per channel, exported individually or as a zip.
