In this video, Christopher 3D explores two new render features in Blender 4.3 dealing with improved physical accuracy. This is the new Oren-Nayar Diffuse Roughness slider in the Principled BSDF; and the new Metallic BSDF node that has a new Physical Conductor option for laboratory measured reflectance data of metals.
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
