Oh, that's one of the layer exports, isn't it? It's normally disabled for non-baking renders. It's enabled by adding “Add Baking Exports to Shader Layers (vm_bake_layerexport)” to the mantra node and setting it True. This setting can be expensive though, in some cases making renders take 2-3x longer. It might get better performance to export it manually be appending a bind export to the texture going into the principled shader's basecolor input.
See the attached scene for examples of adding the proper exports.
Thanks A lot Jonathan! that was what i am looking for, the first wsy is a bit too long to setup especially considering i have 40+ materials in the master scene but baking export should do the trick! thanks again
