release following Project Orange. 2.43 – February 2007: Multiresolution meshes, multi-layer UV textures, multi-layer images and multi- pass rendering and baking, sculpting, retopology, multiple additional panoramic camera for Cycles, mirror ball environment textures and float precision textures, render layer mask layers, ambient occlusion and viewport display of background images and render layers. New import window layouts. Scenes & Layers These data-block menus are used to select the current Scene and View Layer. Workspaces Workspaces are essentially predefined window layouts. Each Workspace consists of a set
