I started with cubemap images of 2560x2560 but some devices displayed black.
I changed to 1024x1024 and 720x720 both worked with all devices but one.
Ran Webglreport on device and report said browser supports it but it is diabled possibly driver update needed. Now in process of doing several OS updates on the device.
In short, after changing resolution my problem seems to now be isolated to out of date device.
I will try and experiment with devices and resolution that causes error and get webglreport.
If in fact images are being resized automatically by PLAYCANVAS what would be optimal settings?
Image size uploaded should probably match image size used (or is it scaled for different devices), what is that size? 512x512 1024x1024
Is PNG format better to use than JPG?
Should image compression be used or no compression?
I was just starting to look at the model viewer kit, but didn’t occur to me that my cubemap viewing might be better with that starting point. Thanks for pointing that out!
