Reflection and gloss maps

[carlcox62]

Where do i plug these 2 maps into ai standard surface shader, i cant find something about that on the internet. The gloss map i would plug into roughness channel under the specular tab?!

Where did these maps come from?

Glossiness would probably go to specular roughness.

And I don't think you need reflection

If is glossiness, then you need to invert it to use as roughness.

This maps are from a bpr texture, such as normal,height,gloss,reflect,albedo or base color and 8k resolution, pretty heavy.

The Specular map is if you are working on a PBR Specular\Glossiness workflow. Arnold uses Metalness\Roughness. There is a Substance PBR guide that will help you understand when and where to use those maps.

You can also convert those textures to TX files and that will speed up the rendering.
