From: seungho Date: Fri, 15 Apr 2022 08:31:41 +0000 (+0900) Subject: Use default PBR shader to the scene-loader X-Git-Tag: dali_2.1.21~10^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3699bd6bb292750152ea1a19f702a641f50c9867;p=platform%2Fcore%2Fuifw%2Fdali-toolkit.git Use default PBR shader to the scene-loader - glTF uses built-in shader for rendering. - glTF features of Emission and Ambient Occlusion are added.
