Space Viewer doesn't open on (older) mobile devices

Issue

The Space Viewer will not open on (mostly older) mobile devices, instead an error message is shown.

Cause

RAM of mobile devices are limited so especially older devices can not load the space and show an error. 

Solution

To solve this problem set the mobile texture size to 256 and the mobile max. texture size to 512, by adding this at the end of the url of the Space Viewer link:

&mobile_texture_size=256&mobile_max_texture_size=512
