What is a PBR texture map?
A PBR texture map supplies surface data to a physically based material. Base color describes color, roughness controls highlight spread, metallic distinguishes metal response, and a normal map adds shading detail without changing the mesh outline. Objectify lists these maps in its texture workflow. Their correct interpretation depends on the shader and import conventions.
Choose the right starting point
Treat a material as a set of inputs rather than one painted image. In a metallic-roughness workflow, base color and numeric surface data have different roles. A normal map changes lighting response, not physical thickness or silhouette. If the object shape is wrong, repainting maps will not repair the geometry.
Work through the handoff
Identify each map and connect it to the corresponding shader input. Check whether metallic and roughness are separate images or packed into channels. In glTF's packing convention, roughness uses green and metallic uses blue. Check normal orientation and color-space settings in the receiving tool instead of assuming filenames fully describe the data.
Limitations and failure cases
Not every renderer uses identical material conventions or extensions. A packed image connected as a base-color map will produce the wrong result. Normal maps cannot close holes or add real relief for printing. Exported material support must be checked against the importer rather than inferred from a convincing preview render.
Acceptance checklist
Inspect the asset under neutral lighting, then compare rough and polished regions. Verify that metallic areas are intentional, base color is not used as numeric data, and normal detail does not appear inverted. Disable maps one at a time to isolate the fault. Keep a record of channel packing and shader adjustments.
