Lots of changes and updates are being made to the SketchUp Mobile viewers. I wanted to open a topic for common issues and their fixes on iOS devices.
Models Are Blank:
This particular issue is recent AND troublesome because I still haven’t pinpointed exactly why this is happening to some users. We do not currently have a fix for this, as I am still collecting data. This item is a top priority. If this is happening to you, please share the following information:
-SketchUp Viewer Version
-Screenshot of any errors you might be seeing
EDIT If you are using an older, 32bit device on iOS version 10.3.3 that is no longer receiving updates from Apple, there is a chance it is using an older version of OpenGL that is not compatible with SketchUp Viewer 5 (the current version). The development team is looking into adjustments in the future to allow SketchUp Viewer to run on these retired devices. The OpenGL incompatibility between iOS 10.3.3 and newer versions appears to be the cause of the Blank or White screen when viewing models.
Slow Responsiveness / Crashing While Loading Large Models:
Currently, SketchUp Mobile Viewer is built to view models up to 10mb in size. I’ve seen examples of successfully viewing models 20 or 30mb in size, but it becomes less reliable as the size increases. There are workarounds, creating scenes and turning off unneeded layers (layers that are not currently being viewed in a scene), reducing complex textures, using entourage components (chairs, foliage, vehicles) with simpler geometry. Possibly using extensions like CleanUp3, or following tips from the Agile Modeler’s Guide. If you have a technique that works for you, share it with the community!
