    Hi all, is there tip to load AO image in 3dsmax material? Sometimes I create my geometry inside 3dsmax and do textures in Substance Painter.PBR output is albedo+metal+rough+normal + AO channel.
    Regards

    It’s little tricky. I made an example for you. A Pure_Black material for imitation of ao.

    Thanks for the quick answer!
    It’a compositing…ok. But it’s not what i would like…I thought there was an AO channel …:(

    AO channel is important because if I want, for example, to change Albedo(color or texture) “realtime” by code, the AO channel will remain the same. Like standard PBR materials in substance, unity( in attachment), ec… Can i Put AO with code?

    As you mentioned the Verge3D engine based on Autodesk Phisical Material, so only they can add or remove any input. But you can use GTLF compatible material then you need to connect your AO to Base Weight Map input of the material and set checkbox
    GLTF 2.0 Compatible on each material, but it has a lot of restriction. I can’t understand whay you can’t change color of the Albedo or the texture by code with the solution I proposed you before?

    YESS IT WORKS!! I thought that 3dsmax materials are “baked” AO+Diffuse. With your trick, I can do what I want… but, what about performance? Here I have 2 materials blended with textures and not 1 material with an Ao texture(as my previous screenshot from Unity). Anyway, this can help for now. Many thanks.

    I think there’s no such a big difference.
