Workflow

Unreal material workflow

Prepare browser-generated PBR maps for Unreal Engine with clear naming, normal compression, linear data maps, and material graph checks.

Export target

Channel setup

Import base color with sRGB enabled and connect it to the material Base Color input.

Set the normal map compression profile to Normalmap so Unreal treats the texture as tangent-space normal data.

Keep roughness and AO as linear data textures with sRGB disabled. Use metalness only when the material actually needs a metallic response.

Use height for parallax, displacement, or virtual heightfield workflows only when the target material graph supports it.

Export the aligned PBR map set and keep channel names visible so Unreal imports are easy to identify in the Content Browser.

Drag the PNG maps into the project folder, then set compression and sRGB options before building the final material.

Create a material, add Texture Sample nodes, connect base color, normal, roughness, and AO, and leave height disconnected unless the shader uses it.

Apply the material to representative geometry, adjust UV tiling, and test roughness under the same lighting family used by the level.

Disable sRGB for roughness, AO, height, and packed data maps or the material response will shift.

A normal map imported as a default color texture can create soft or broken lighting. Use the Normalmap compression setting.

Use the bundled orm.png where R=AO, G=Roughness, and B=Metalness; keep sRGB disabled on the packed map.

Yes. Roughness is scalar data, so sRGB should be disabled to preserve the intended material response.

No. The current export provides map files; the Unreal material or instance is still assembled inside the project.
