From 68d1f091583168dce4e52d3c7378b9b0359e903a Mon Sep 17 00:00:00 2001 From: Jeroen Bakker Date: Tue, 27 Aug 2019 15:47:30 +0200 Subject: Shading Modes: Material and Render Preview This change implements the basics as described in {T68312} for the shading modes. * LookDev shading mode is renamed to Material Preview. It always uses Eevee as renderer, and is intended to provide a fast material preview suitable for texture painting, and texture and material setup. * Rendered shading gains "Use Scene Lights" and "Use Scene World" options similar to current Material Preview. These will be enabled by default. When Use Scene World is turned off, HDRIs will be used for lighting instead. These options are available for EEVEE and Cycles. * Renderers will be able to customize the shading settings panel and add additional settings.
