i bought the viewer just to see it crash with my latest model. using an ipad  mini MF084LL/A with IOSv 11.0.2 here... what are the minimum specs and what are the limits for geometry / textures etc?

From my understanding there is not a set "size limit" when loading files in the viewer because it varies on the hardware of the iOS device.  For example a 512gb iPad Pro will handle a larger file that a 64gb iPad could not, but this device would be able to handle a file that a 16gb iPad Mini 2 could not handle.

yes that's what i mean: what are the limits for given ipad models? is a file with 1.3 million faces totally far from being handled on an ipad? the demo files rather suggest this is a viewer for logos, small objects only. wish i did not pay 10 EUR for a toy...

I don't believe there is any set formula between the file size and iPad model because there are too many variables to consider.  Two different models with 1.3 million faces will likely have two very different file sizes, accommodating for textures, lights, clipping planes, etc.  

 

Also, since there isn't any dedicated RAM in any iPad so the size of the file depends on exactly how much room is available on the iPad.  An empty 64gb will open larger files than a 16gb iPad with 1gb free because it has more space to allocate for "memory."

 

Not sure if this helps but I just opened a 130mb file on an iPhone 6S with ~10gb storage available (running iOS 11.1) without any issues.

sounds good, as my file was even smaller than that. maybe other issues made it crash. i don't know if the developers get log files and crash reports automatically from the app. i will try again with other files as soon as i have more time - but the first impact was: application just quits, no error report, nothing.
