1.3.3 Update — Putty 3D

Hi everyone,

Here are the changes for update 1.3.3:

Fix for black photo rendering on iOS 11
Fix for STL export
Added support for binary STL export
Changed the way the flatten tool works, with it now being relative to the surface orientation and not the camera direction
Improvements to the way we handle video recording (unfortunately there seems to be an overall iOS video recording issue that might cause the first recording to save)
Initial support for iPhone X
Small localisation fixes
