we are trying to convert our materials to gltf-compatible, to cut down on loading time.
most of our materials are a pricipled shader + ambient occlusion mixed in.
usually mixed into base color + specular (see attachements), or mixed to black via a shader mix node (this has some issues with the gamma beeing different in the browser though).
now, verge3d-3-4-for-blender-released states that
Finally, there is now possibility to use external occlusion maps in gltf-compatible materials (before AO had always to be packed to the ORM texture).
but, it is not described how this can be done.
docs/manual/en/blender/GLTF-Materials
also does not mention this.
how can we set the nodes up, so that the ambient occlusion is used in a gltf material?
also, part2: some of our material have the ambient occlusion baked into vertex colors, is there a way to use these?
.
