Material Preview

Texture maps are hard to judge flat. A normal map is a sheet of pale blue and a roughness map is a gray smear. Neither tells you much until a light hits it.

This puts your maps on a lit sphere or cube so you can look at the material as a material. Load whichever maps you have, move the light around, and the usual problems show up straight away: normals pointing the wrong way, roughness so flat that everything looks like plastic, AO so strong it reads as dirt.

My normal map looks inside out here.

That is the DirectX and OpenGL green channel difference. Run it through Flip Green and load it again.

Which maps do I have to load?

None in particular. Empty slots fall back to neutral values, so you can preview a normal map on its own.

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.

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.

Rough ↔ Gloss: Convert a roughness map to glossiness or smoothness and back, for assets moving between engines that expect one or the other.

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.
