So I have been playing around with node materials and am using a PBRMetallicRoughness node. What I would like to do is plug in a light map for my over all lighting but I am struggling on how best to do that. I have worked a fair amount in the past using PBRMaterial and setting up a light map for those is pretty straight forward. However, as I don’t see a light map attribute for PBRMetallicRoughness I am not sure how best to go about setting things up.
Anyway, I am hoping that someone may be able to point me to an example of how best to take advantage of lightmaps using the node material and PBRMetallicRoughness.
