How should texture import settings be configured for albedo, normal, and metallic maps to achieve a good PBR result?

• A. Albedo textures use sRGB color space; Normal maps require a normal map type; Metallic/Roughness should be set as Non-Color Data; adjust compression and max size appropriately.
• B. Albedo textures use sRGB color space; Normal maps require a Normal map type; Metallic/Roughness should be set as Color Data; adjust compression and max size appropriately.
• C. Albedo textures use Linear color space; Normal maps require a Normal map type; Metallic/Roughness should be set as Non-Color Data; adjust compression.
• D. Albedo textures use sRGB color space; Normal maps require a Normal map type; Metallic/Roughness should be set as Color Data; set compression to high quality.

Answer: (A)

In PBR texture work, you want albedo to be sampled in sRGB color space because it represents visible color and should go through gamma correction to match how we perceive hues and brightness. Normal maps must be imported as a Normal Map texture type so the engine decodes them into correct tangent-space normals for accurate lighting interaction. Metallic/Roughness maps contain grayscale values that describe physical properties, not color, so they should be treated as Non-Color Data to prevent any color-space or gamma adjustments from altering those values.

Together, these settings preserve the intended color, lighting response, and material properties, giving a faithful PBR result. If you instead mark the metallic/roughness map as Color Data, or use Linear color space for albedo, or otherwise mishandle the data, you’ll distort how metallic and roughness affect specular highlights and shading, or you’ll dull colors and misrepresent textures. Adjusting compression and max size helps balance detail and performance without changing the fundamental data interpretation.
