You need to know this about Specularity in Blender 4.0

The upcoming Blender 4.0 currently in development has made an important change to how the Specular function in the Principled BSDF operates. This video talks about that and how to use this important change. NOTE: It’s possible the Principled BSDF UX may change by the time the final release comes out, but I’m pretty sure this functionality will remain as is. You can also watch my video on other improvements to rendering in 4.0 here. 00:00 Introduction 00:17 Basics of Specularity 00:43 Index of Refraction 01:33 The basic change made 03:11 Specular Neutral 03:18 Specular & bitmaps 05:07 Specular & Dialectrics 07:03 Creating diffuse-only surface (important!) #specular #blendertutorial #fresnel #refraction #ior
