What's New in Viewport 3D
1.0.2
July 17, 2026
AR, large-file, iPad, and rendering improvements: • Fixed textures appearing distorted or stretched on some glTF/GLB models. • Sharper surface detail — normal maps now stay locked to the model as you orbit. • Improved stability and memory use for very large GLB files. • Rebuilt AR placement with a clearer target, steadier surface placement, realistic shadows, and improved model sizing. • Added Real World and Studio lighting options in AR. • Added full iPad support with adaptive layouts and multitasking. • Fixed the final Recent Files row being cut off. • Clearer message when a file has no displayable surfaces. • Improved initial model framing so objects open fully visible. • Improved stability when switching or closing models while background preparation is running. Thanks for using Viewport!
