# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
