Sketch 3D is a tool for designing 3D models from your fingertips. You could download models from others, and could also share your great designs with other users by saving models in Public space. New Feature: Integrated MaterialX library into the app. Mesh object can be applied with materialx documents. When Saving and Loading with material, the document relative path is stored as a diffuse map entry, similar to the way of handling movie textures. Other features like material adjustment and graph editing are not supported yet. User could download free material documents from public websites and import those zip files with this app, using ShareTo or AirDrop. Feature: Use True Depth Camera to capture face model. Feature: Support using video as model texture. You could use video clips from Photo Album, or from Internet URL (YouTube URL not supported), and then apply it onto a model as texture map. Feature: Capture movie from the 3D scene. Note! If your device could not capture movie, then, could try out a smaller output resolution (by tapping the control pane). However, arbitrary output size may stop capturing prematurely. Feature: Design 3D model animation with skeleton structure. You could design a skeleton structure by placing bones in hierarchical relation. Attach model to the skeleton, and then moving the bones to define different poses. Each pose represented as a keyframe in the timeline view. And animation sequence is produced by playing interpolation between the keyframes.
