As I've been learning Blender and practicing a PBR workflow, the general consensus I get from others here and on different communities is this:
- Keep the specular value to 0.500 for most objects.
- Utilize a node group to convert IOR to the appropriate specular value.
What I'm really after though is a happy medium between the above two approaches. Sort of "general guidelines" to follow. What kind of materials generally have high, or low specular values? Is this something I can look up for both dielectrics and metals?
Any guidance would help. Thanks.
