Certain sRGB values for one workflow, IOR values for the other workflow, depends on what you choose.
It seems to me that what you mostly need to stick to is to the 'measured data'. What do you think about the best option? Next Wednesday will be on the location of a construction I want to map the materials, to develop a version of his simulation with maximum similarity (there will be also other versions more relaxed in term of realism).īased on current PBR workflow a better way will be use the photos just as reference and use product such as Mixer to achieve the result 'mixing' other available Megascan materials and decals, or better use the actual photos and products such as Materialize to create the final material, as from the beginning of the thread.
