I’m wondering how should I figure this out.
I need to have multiple texture maps combined together and injected to PBR Material’s texture slot.
For example. I need to create brushed stainless steel shader. In this case, we have two different maps from two different projection types. Brushed_normal.jpg which follows the planar mapping, to add details for models we use Object_details_normal.jpg which follows Unwrapped UV layout. Now we need to combine these two maps together and inject them to PBR normal map texture slot. I could not find a straight answer to this question.
