PBR Map Generator for Unreal Engine Materials FAQ
Does one-click Unreal export create a native Material asset?
No. Select Unreal and click Unreal ZIP once to download the target-oriented package. You still import the textures, choose compression and sRGB settings, build or adapt the Material, and test it inside the project.
When does packed ORM get included?
Packed ORM is included when ambient occlusion, roughness, and metallic maps are all present in the generated set. If one is missing, the package should preserve that fact instead of hiding it.
What channel order does PLAYTEX AI use for Unreal ORM?
PLAYTEX AI uses the common Unreal-oriented convention R = ambient occlusion, G = roughness, and B = metallic for its packed ORM output.
Why does Unreal need the DirectX normal preset?
The current PLAYTEX AI Unreal preset uses the DirectX Y- convention. A mismatched green channel can make raised detail appear recessed, so keep the preset selected and still validate the imported normal under moving light.
Which Unreal texture maps should have sRGB disabled?
Technical data such as ORM and other grayscale masks should normally use linear sampling, so disable sRGB when the material expects raw values. Base Color is ordinary display color and usually keeps sRGB enabled.
Why does the imported Unreal normal look inverted?
Confirm the Unreal preset used the DirectX Y- convention, the texture is imported as normal data, and the material samples it correctly. A green-channel mismatch can make raised details appear recessed.
