# What is the correct naming convention when importing PBR maps with one click?

The PBR material system contains two sets of workflows, the metallic/roughness system and the specularity/glossiness system, which D5 supports belongs to the metallic/roughness workflow. The texture imported by the user should conform to the suffix naming rules of this workflow in order to correctly identify the material effect.

The Metallic/Roughness workflow mapping suffix naming and mapping slot corresponding rules are as follows:

  * \[ Base color \] slot：\_color（\_col） /\_base color /\_basecolor /\_albedo

  * \[ Specular \] slot：\_specularLevel

  * \[ Metallic \] slot：\_metallic / \_ metalness

  * \[ Normal \] slot：\_normal（\_nrm） /\_bump

  * \[ roughness \] slot：\_roughness(\_rough)

  * \[ AO \] slot: \_ambient occlusion(\_ao)

  * \[ Opacity\] slot：\_opacity

  * \[ Height \] slot：\_displacement(\_disp)/\_height

Other mapping suffixes may cause incorrect effects or failure to import, so please correct them yourself. Among them, the normal mapping format used by D5 is Direct X.
