cant get an alpha from a specular material
Moderators: ChrisHekman, aoktar
i need to deliver a rendering of a bottle with an alpha channel so i can be composed on several different backgrounds. i cant manage to get a transparent alpha channel or object ID pass for the glass out of octane. Its always completely solid as it would be with an opaque material.
Octane_material->Common->Affect_alpha is your friend.
