For my project need to be able to change by scripting the materials properties.
Looking at Megascans as potential source for base materials I can use to derivate a new set, want to know where I'm starting from, so if there is any documentation about the base value used to create these materials.
Since Mixer it's not scriptable I wil need to change the materials in another tool, starting with them as base reference.
There is any structured materials parameters database from whom I can start from.
